Hajime Asaoka: Chrono and Kurono, Bunkyō Tokyo

Hajime Asaoka’s more-affordable watches define the current trend of “must-have” limited-edition watches. An AHCI watchmaker, Asaoka-san launched a line of affordable watches in 2018 for the domestic market in association with the TiC TAC retail chain. These watches, labeled “Chrono Tokyo”, soon proved irresistible to the international watch collecting community, so a companion line, “Kurono Tokyo”, was launched the following year. In this article, I will walk through every Chrono and Kurono watch through 2021, providing some context and clarification for collectors worldwide.

Hajime Asaoka, Watch Craftsman

Too often, Hajime Asaoka is credited as “The Japanese Philippe Dufour”, comparing him to an independent watchmaker revered in his home country more than any other. While I’m sure that Asaoka-san is flattered by the comparison, it is not appropriate to focus on his work through the filter of his nation or origin. Hajime Asaoka has earned the respect of the watchmaking world not by being the best in Japan but by being one of the top craftsmen of watches in any country. This is why he was quickly accepted in 2015 into the Académie Horlogère des Créateurs Indépendants (AHCI).

There are three “true” Hajime Asaoka models, but none are mass-produced or even really series produced. The three-handed Tsunami, Project T tourbillon, and chronograph are built by hand by Asaoka and a small team of watchmakers in his studio. From the beginning, each piece was truly custom-made, a process which Asaoka himself likened to “playing a game of chess with my clients” in a 2018 Europa Star interview. Thus, his watches are traditional but filled with unexpected twists, restrained but exceptional.

These watches are in such demand that they are essentially unattainable today. Like Dufour, Asaoka has a years-long waiting list and produces just a few examples a year. While his output has likely grown beyond the 19 watches he had produced as of that 2018 interview, it is impossible for an independent watchmaker to meet the demands of a global audience without compromising quality or switching to mechanized production. In 2020, it was revealed that Asaoka had produced just “4 Tsunamis, 2 tourbillons and 1 chronograph.”

I strongly suggest following @HajimeAsaoka on Twitter! Although his feed is in Japanese, it is a marvel of photos and information for watch nerds!

Hajime Asaoka created the Chrono Tokyo line as an affordable alternative to his atelier watches. He explained that he did not even have one of his own watches to wear, since they take so much time to build and he focuses on the needs of his clients. And he expressed sadness that ordinary people could not purchase and wear his watches.

Chrono Tokyo First Series, October 2018

TiC TAC is something of an institution in Japan, a retailer of the watch lifestyle as much as of watches themselves. Since 1984, the store has stocked more obscure and interesting brands, including Ikepod, Junghans, Lip, Mondaine, Mühle Glashütte, Nomos Glashütte, Stowa, and Seiko’s Astron, Presage, Prospex, and Spirit. The company has expanded, with themed stores in many cities.

In early 2018, Asaoka revealed that he was working on a new watch, produced in volume with an off-the-shelf movement. The Chrono Tokyo line was introduced in April 2018, for sale exclusively at TiC TAC in batches of 50 examples at a time. The prototypes used Miyota’s 9015 movement, a respected automatic watch movement from the Citizen subsidiary introduced at BaselWorld in 2010, though production models use Cal. 90S5. Asaoka clarified that this eliminates the date function, which the watch does not need, and improves the swing angle of the balance.

Through his Twitter account, Asaoka discussed the development and creation of the watch, including the special hands he designed and constructed. Production of the watch was outsourced, but Asaoka’s Precision Watch Tokyo Co. handles most aspects of design, ordering, final inspection, and shipment. Asaoka’s Twitter feed shows how intimately he was involved with every aspect of the watch, from the packaging to the strap to the dial to the brochure. In a tweet of the final Chrono Tokyo manual photograph, he said “today I’m taking a picture of my soul.”

The first Chrono Tokyo series was released for sale on October 12, 2018. Two references were produced, with champagne or gray dials, each with contrasting accents. The initial production run was 50 watches across both color ways, with 26 champagne and 21 gray examples produced.

The hand set is differentiated but complementary, with the minute hand’s fountain pen style particularly striking. And the case is mirror polished. The entire package resembles the classic dress watches of the late 1950s, notably the obscure Japanese brand Takano, which was the foundation for Ricoh’s watchmaking in the 1960s.

The dial is a fresh interpretation of a classic design, with applied markers at the four cardinal points above a concentric inscribed grooves. It is a so-called cylinder dial, with a raised center requiring curved markers and hands. This was difficult to source, with the company claiming that only one company in Japan was able to produce it.

The “champagne” dial has a creamy color to it in some images, and is a refreshing change from contemporary stark silver dials. And the gray has an organic slate hue that provides a nice contrast to the polished markers and hands. It is not entirely clear what straps were finally used, as Asaoka frequently shows the watches on a wide variety of straps. But I prefer a supple leather for a streamlined watch like this.

The gray dial version would be reissued the following year as part of the international Kurono Tokyo edition (see below).

Chrono Tokyo Second Series, June 2019

It would be almost a year before another Chrono Tokyo watch was released. The second series appeared in mid 2019, with a June 2019 release date. These were quite similar to the first series apart from different dial colors.

The first Chrono Tokyo prototype in April 2018 featured a blue dial, but this was not included in the first production run. Thankfully, the second series rectified this omission! The second new model had a creamy “vanilla beige” dial that did more for the polished markers and inscribed grooves than the original champagne.

Unlike the first series, which included just 50 examples combined, the second series included 50 of each color. Both models would be reissued under the Kurono Tokyo brand that same month as well.

Kurono Tokyo First Series, June 2019

Although the Chrono Tokyo models were intended only for the domestic market (indeed, they include the TiC TAC name on the case back) they received a great deal of attention from watch collectors abroad. For this reason, Asaoka created an “export” brand to serve international collectors via e-commerce.

Unlike the classic boxed “CHRONO” logo on the domestic models, the international brand was “Kurono”. These names are effectively identical to a native Japanese speaker, since the Katakana version of “Chrono” is “クロノ”, or “Kurono” in “Romaji.” The international models also add “Bunkyō” to “Tokyo”, the name of the special ward in which the Asaoka workshop is located.

The first series of Kurono Tokyo watches included three references: “Mystic Gray” (Ref. CB001G) was similar to the first-series Chrono Tokyo CT001G and “Midnight Blue” (Ref. CB001B) was similar to the second-series Chrono Tokyo CT002B. The price was $1,750. 50 examples of each were produced and sold online, launching the Kurono Tokyo brand. Additionally, “Eggshell White” (Ref. CB001E) was issued for Sincere Fine Watches of Singapore and is similar to the other second-series Chrono Tokyo model, CT002V.

The first series of Kurono Tokyo watches was announced for sale on June 3, 2019. The Gray model sold slower than the other two, remaining available for over a month. This would be the last time a Kurono Tokyo watch was available for regular e-commerce purchase. Deliveries of the Blue and Gray watches were delayed due to an issue with the quality of the dials, so the Eggshell model was the first Kurono Tokyo watch to be delivered. Regular shipments started in September.

Kurono Tokyo “Reiwa” Second Series, November 2019

Coinciding with the third series Chrono Tokyo watches, Kurono Tokyo released their “Reiwa” editions. The name refers to the current era of Japan’s official calendar: The Reiwa era began on May 1, 2019 as Naruhito ascended the throne as Emperor of Japan. So 2019 is known as “Reiwa 1” in the calendar.

These are essentially international editions of the third-series Chrono Tokyo watches with the Kurono Tokyo dial branding. Interestingly, the descriptions were changed for the international market: The Classic “Steel Gray” became the Reiwa “Silver”, while the Classic “Bronze” is known as Reiwa “Copper”. But the colors appear very similar, so it is likely that they are identical.

The Reiwa models shipped with a genuine crocodile leather strap. It is a “square scales” leather in matte black.

Kurono Tokyo issued 50 examples of each reference, for a total of 100 “Reiwa” watches produced. These were announced on November 20, 2019, went on sale on November 25 at 13:00 PM JST. The Copper model sold out in 6 minutes, with the Silver version lasting just 16 minutes. Shipments began in March, 2020, despite the pandemic.

One curious appearance of the Kurono Tokyo “Reiwa” Silver is in the 2020 film, The Invisible Man. Actor Aldis Hodge chose to wear the watch during the film out of respect for Hajime Asaoka, according to Quill & Pad.

Kurono Tokyo released a urushi lacquer box on March 19, 2020 as a separate purchase. Priced at $187, the box was limited to 80 pieces. The box sold out in less than a day and has become a popular accessory for the Reiwa and other Kurono Tokyo models, drawing “flippers” just like the watches. Delivery of the boxes was delated due to the pandemic, however.

Curiously, the first five Kurono Tokyo references are no longer listed on the official website. And Hajime Asaoka assiduously avoided showing images of the Kurono models on his Twitter account. The Kurono Tokyo Instagram and Facebook pages are written differently, commonly referencing “Hajime-sensei” but not in his words.

Chrono Tokyo “Classic” Third Series, December 2019

Asaoka created a new dial in 2019 for the third series of Chrono Tokyo watches. Known as the “Classic” dial, it is an evolution of the original with a black center section and dynamic colored outer track. From Asaoka’s Twitter feed, it seems that these dials were more difficult and expensive to produce than the original, but it makes a dramatic difference in the look of the watch. Yet the design of the dial remains much the same, apart from the colors.

The “Steel Gray” model has a champagne outer track similar to the original CT001W. The center section is similar to the dial of the original CT001G, making this reference a combination of both original Chrono Tokyo models. But the combination is a thorough transformation of the original, making the Classic one of the most desirable Chrono Tokyo references.

The other third-series Chrono Tokyo model features a stunning new bronze dial, completely changing the look of the watch. The outer section is like a neon sign in the dark when compared to the glossy inner dial, and gives it a chocolate brown hue. The contrast between the bronze dial material and cut grooves along the edges adds a deep visual detail not seen on any previous model.

50 examples of each reference were created, bringing the total number of Chrono Tokyo watches to date to 250.

Kurono Tokyo Chronograph 1, April 2020

The first all-new model appeared on April 28, 2020: The Chronograph 1. This was the first time that an affordable watch was announced and released for sale first under the international Kurono Tokyo brand rather than the domestic Chrono Tokyo label.

The Chronograph 1 uses the Cal. NE86A, a two-subdial variant of Seiko’s Cal. 8R family. This is an upscale column wheel chronograph movement with a novel vertical clutch system operated by a three-pointed reset hammer, so the chronograph function works especially smoothly. The Kurono Chronograph is modified to remove the hour register at 6:00, replacing it with a date window. It includes a 30 minute counter at 9:00 and running small seconds at 3:00. This movement is produced by Time Module, Inc. which is Seiko’s OEM movement arm.

Although it is not a modular movement, Cal. 8R is not an especially thin watch movement, measuring over 7 mm thick. This means that the Kurono chronograph is quite a bit thicker than the previous slim time-only models. Asaoka’s case de-emphasizes the bulk using a thick caseback below the central case band, but it still sits quite high on the wrist. This is made worse by the use of a boxed crystal, which Asaoka prized as it helps magnify the outer tachymeter track and helps exemplify the classic styling. The minutes counter includes a special hand shaped like a traditional Japanese “kyūdō” arrow.

Two references of the Kurono Tokyo Chronograph 1 were released in 2020, with black-on-white and white-on-black dials. Each was priced at $3,680, the most expensive to date. These were issued in a limited edition of 68 pieces of each, for a total of 136 pieces. Sales began at 10:30 PM Japan Standard Time on May 1, 2020, and sold out almost immediately. Production was delayed due to the pandemic, but deliveries began in October, 2020, almost two months before the Chrono Tokyo version was released for sale.

In the months before the release of the Chronograph 1, Kurono Tokyo clarified that there would be no waiting list for any product. Instead, the company would focus on global ordering, with a pre-order period for collectors and supporters.

Kurono Tokyo Anniversary Green “森:Mori”, May 2020

Kurono Tokyo celebrated the first anniversary of the brand on May 22, 2020 with the release of a special model with a bright metallic green dial. The watch is named “森:Mori”, a Japanese word meaning a forest or woods, and appears to have been chosen to celebrate the deep green dial. The Kanji “森” is pronounced “mori”. Although the watch went on sale in May, it was meant to celebrate the anniversary of the brand, which was set to June.

The Anniversary Green “森:Mori” watch was announced May 11 and went on sale at 10:30 PM JST on May 22, 2020. It was priced at $1,790. 50 examples were promised, but sales were so strong that the series sold out in 42 seconds, and their ordering system had issues completing sales. The company decided to reopen sales at 12:30 AM JST for 10 minutes, allowing additional orders for those that had missed out on the first run. After eliminating duplicate orders and cancelling orders from known “flippers”, the company ultimately produced 288 pieces. Shipments began in June, 2020.

Due to the “overtly meticulous” inspection of Hajime-san, 17 of the initial 50 Mori watches were rejected before being shipped. An additional 3 watches were reported to be imperfect by customers and returned. The company communicated proactively with customers, improved packaging, and switched shippers to protect the watches in transit.

The success of the 森:Mori model lead Kurono Tokyo to implement stronger limits on sales. The company spoke out against “fake accounts” and “known traders.” During “Mori Mania,” the company cancelled orders with “incomplete/dubious information” in order to limit customers to purchasing one piece for their own use only. This caused a great deal of anger in the community, both from those who claimed to have been unfairly excluded and those defending the rights of buyers to re-sell watches as they pleased. Over the next months, Kurono Tokyo stuck to this philosophy and continually refined their sales processes to limit orders to buyers they considered to be genuine enthusiasts.

The Anniversary Green “森:Mori” was pre-selected by the Grand Prix d’Horlogerie de Genève in the “Challenge” category. This includes watches priced under CHF 4,000. The Chronograph 1 was also pre-selected in the Chronograph competition. Although neither was selected for the win, this dramatically raised the profile of the brand.

In June, 2020, Kurono Tokyo announced that they would be offering a free “provenance extract” service to owners. Once per ownership, owners can request an extract from the archives using the company’s website. No doubt this was also implemented to tamp down on “flippers”, which had become the bane of the company’s success.

July 2020 saw the announcement of a special coffee table book of contributed photographs. The book, Celebrating Collectors, quickly sold out but is available as a digital edition for free on the company’s website.

In August, Kurono Tokyo announced that they would send a special bracelet to all Kurono owners as a sign of appreciation. These went to 2020 Kurono buyers and were included with watches that shipped later.

A second set of collectible boxes was announced in September 2020. These were based on a historic ukiyo-e piece by Hiroshige acquired by the brand. Priced at JPY33,800 or $319, the boxes were released for sale on October 7, 2020 and quickly sold out.

A leather strap featuring the Hiroshige poem was announced two days later. Released for sale on October 9, 2020, it sold for $129 and quickly sold out.

Chrono Tokyo “Bullseye” Fourth Series, June 2020

The final series of Chrono Tokyo time-only watches were released for sale on June 16, 2020, though Asaoka had shared images of this dial even before the third series was released.

The so-called “Bullseye” model dispenses with the inscribed grooves found on all previous Chrono Tokyo models, opting instead for slim Arabic numerals. The outer track is similar to the previous models, and the hands are the same, but most other elements are quite different. The strap is made of “goat leather”, an unusual material for a watch strap.

These two references can be seen as a reflection of the original Chrono Tokyo models, with Champagne and Field Gray dials. The Champagne model has a classic look, with the dark outer band contrasting strongly with the center of the dial. But the Field Gray is radically different, with orange printing on the dial and outer track. It retains the glossy hour track, which provides more contrast and interest to the gray dial.

50 examples of each color were produced, bringing the final total production for time-only Chrono Tokyo models to 450.

Kurono Tokyo Grand:Akane, November 2020

The final release of 2020 was an all-new watch, different from any previous model. The Grand:Akane features a unique urushi lacquer dial in bright red. The pattern, known as Hamon (刃文), is finished with a traditional chemical treatment known as Niiro (煮色). Finally, a layer of transparent lacquer (suki-urushi) is used to fix the pattern. The indices are metal and resemble the “Bullseye” Chrono Tokyo model, but the overall look is completely new.

The name refers to the deep red color of the dial (“Akane” in Japanese) and the character printed above 6:00 is the associated Kanji character (茜).

The Grand:Akane was announced on November 16, 2020 and released for sale at 11:30 PM Japan Standard Time on November 25. The first truly international Kurono Tokyo model, the Grand:Akane was priced at JPY 350,000 or $3,320. The entire stock was sold in 1.5 minutes globally, with 70% of stock released to the public and the remaining 30% reserved for “contributors” and “collectors” who expressed their interest via email by November 18. In the end, only 8 of 12 offered to “Contributors” were claimed, so four were returned to the public pool. 144 were sold to the public, 48 to Collectors, and 8 to Contributors. Five “scalpers” were detected and their orders later cancelled.

The urushi dials proved challenging to manufacture. Kurono Tokyo revealed that over 50% of the initial batch were rejected by Asaoka, stretching delivery times. But subsequent batches improved, with 80% acceptance rate. The first shipments began at the end of February, 2021.

In 2021, the company revealed the Kurono Tokyo Grand series of watches. These “signature” models would feature Hajime Asaoka’s signature on the case back. Judging from the Grand:Akane, it is likely that they would be higher-cost models with special dials.

Chrono Tokyo Automatic Chronograph, November 2020

In August, 2020, Hajime Asaoka began talking about a Chrono Tokyo version of the Chronograph 1. This would be the final product of the Chrono Tokyo brand, which was retired in January 2021.

The Chrono Tokyo Automatic Chronograph was essentially identical to the Kurono Tokyo Chronograph 1, which was introduced in April. It included the same dial design and colors and the same functions and hands. The only notable differences were in branding: The “CHRONO” logo on the dial and the caseback. Two references were released, white-on-black and black-on-white. Curiously, the reference numbers, CH001K and CH002W, respectively, include a different digit. But the models were designed, released, and shipped together. Later reports suggest that the white dial models are labeled CH001W, so perhaps this initial numbering was an error.

Sales of the Chrono Tokyo Automatic Chronograph started November 20, 2020, with deliveries in November. 50 examples of each were produced.

On January 3, the Kurono Tokyo Facebook page revealed that “effective from 2021, all global and domestic markets will be consolidated under the #kuronotokyo brand name.”

Kurono Tokyo Chronograph 2, February 2021

The next announcement after the cancellation of the Chrono Tokyo brand was the global Chronograph 2 model. The design was teased with an image on the Kurono Tokyo Facebook page on January 3, along with the announcement that all future models would use the Kurono Tokyo brand. But it wasn’t until February 10, 2021 that the Chronograph 2 was officially announced.

The Chronograph 2 features a new dial design with a brown center and orange accents, somewhat reminiscent of the “Bullseye” Field Gray model. All other elements of the watch are similar to the previous Chronograph 1, including the special hands, the case, and the strap.

The Kurono Tokyo Chronograph 2 was released for public sale on February 20, 2021 in two batches: Public international sales began at 11:30 PM JST, while domestic sales started at 12:00 PM. The model sold out in under 3.5 minutes despite the large 500 piece production run. The watch was priced at JPY418,000 or $3,993, the highest for any Chrono or Kurono model to date. 20% of the stock (100 pieces) were reserved for the domestic market and for Kurono Contributors.

Deliveries of the Chronograph 2 began in early April, with mine arriving in the United States on April 12, 2021.

A new line of Hiroshige straps were announced in January 2021. The new strap is made of yellow calf leather(karashi-iro or Sahara) and was priced at JPY13,850 or $129. These were sold starting on January 20, 2021 and were sold out by January 26. The company also announced their own logo strap tool, which was included with strap orders.

A bamboo (green) leather strap featuring the Hiroshige poem was announced on April 28, 2021. Released for sale on April 30, 2021, it sold for JPY14,800 or $135 and sold out in a few days.

Kurono Anniversary Coral 朱鷺:Toki, May 2021

On May 14, 2021, Kurono announced the second anniversary watch. Known as 朱鷺:Toki, it features a coral radial sunburst dial in the style of the previous Anniversary 森:Mori watch. The strap is black calf leather with exposed stitching.

The name, 朱鷺:Toki, refers to the Japanese Crested Ibis, which has a partially bare head with red skin. This endangered bird species was introduced back into Japan in 2008, with the first chicks hatching there in 2012. The bird’s distinctive coral-colored head inspired the name and dial color. The dial is officially described as “coral” on the Kurono Tokyo website.

As an Anniversary model, Kurono Tokyo promises to produce as many watches as are sold in 10 minutes, starting at 23:00 JST on May 21, 2021. The company’s Instagram account later clarified that there are limits to the numbers that can be produced, though they claim to have calibrated production capability to expected sales. Shipments are promised in mid-June, 2021. The Anniversary Coral 朱鷺:Toki is listed at JPY189,900 or $1,738, excluding taxes. This is slightly less than the previous anniversary watch.

Kurono Tokyo Bluish-Green 青磁:Seiji, September 2021

On August 24, 2021, Kurono announced a surprising release: The 青磁:Seiji was aimed specifically at women, with a blue-green lacquer dial and white strap. The launch was contentious, with some objecting to the initial offer for sale only to women as well as the the “men won’t get it” tag line. These restrictions were soon modified, with the company apologizing for the controversy but sticking to the concept of drawing more women into their community.

The 青磁:Seiji was only the second lacquer dial watch from Kurono, following the Grand:Akane of the previous year. But the 青磁:Seiji features the classic Kurono dial rather than the simple applied numerals of that Grand model. The white leather strap and blue-green lacquer, which many compared to the colors of New York jeweler Tiffany & Co., gives the watch a feminine look without resorting to tropes like hearts, jewels, or yellow gold. It also made the watch attractive to men, who are increasingly interested in such gender-neutral designs and softer colors.

The initial August pitch would have included 388 examples of the 青磁:Seiji with sales limited to women. Three tranches were to be offered: 10% to 2021 Kurono contributors, 50% to existing watch customers, 10% to existing accessory customers, all with an application form on August 26, and the remaining 30% open to the public in a sale starting at 22:30 JST on September 3. It would have included a “nomination” process whereby men could nominate women to buy the watch, and verification of gender using social media profiles.

After much backlash, this concept was scrapped, with an August 25 announcement revising the release to 500 examples, 50% of which were allocated to contributors (38) and existing watch (172) and accessory (40) customers and the remaining 250 released to the public with no restrictions. Fulfillment was also modified, with the original 388 examples delivered in October and the remaining 112 in January. The price was JPY197,000 or $1,793 excluding taxes.

Hiroshige 三色: Sanshoku is the name for a trim-color Hiroshige strap offered for sale on January 31, 2022 with sales starting February 4. The price was JPY18,300 and it did not immediately sell out, with orders still available in mid-February. Deliveries were promised in March at first but were later scheduled for April and May.

A Complete List of Chrono Tokyo and Kurono Tokyo Models

A note on Kurono Tokyo reference numbers: Chrono Tokyo models are consistently described on the TiC TAC site using a simple reference numbering system. With the exception of the Chronograph, it is an easy way to understand the order of each model. The Kurono Tokyo models also have a consistent reference numbering system. Although this is not widely used in official materials, the reference number makes up the first 6 characters of the serial number.

As of February, 2021 and the Chronograph 2, total production of Chrono Tokyo models is 450 pieces, 100 of which are Chronograph models. Total production of Kurono Tokyo is 1,374 pieces, 636 of which are Chronograph models. Grand total production is 1,824 pieces, excluding prototypes. This page will be updated with production numbers for the Anniversary Toki once sales are completed.
