This page contains the original documentation that came with my Buren Calibre 82 wristwatch, along with English translations of the original German text.
The first BUREN Edition with the legendary “Calibre 82”
1 Two barrels. 2 Minute wheel.
3 Oscillating system. 4 Kif shock protection. 5 Fine adjustment.
Edition No. 55
1 Winding the watch
Before first use, the watch should be wound by turning the crown clockwise by hand to ensure adequate preload is achieved. The automatic movement is then kept in operation while wearing the watch through the bidirectionally winding rotor.
2 Correction of the minute and hour hand (time setting)
After the winding crown is pulled out, the desired time is set by turning the crown clockwise (fig. 2) To ensure accurate hand position relative to the time, the second hand has a locking mechanism.
If you pull out the crown, the second hand stops, so that it is possible to set the watch to the second. At the sound of the time signal on the radio – and the position of the second hand at the 12 – the watch can be restarted by pressing on the crown again.
Do not forget: To prevent the penetration of moisture, the crown must be pushed back firmly against the case when the adjustment is complete with the crown pulled.
3 Setting / date setting
The calendar is programmed for 31 days. If the month has fewer days, the date must be manually corrected. If the month has 31 days, the date display is switched automatically.
Pull out the crown. Turn the crown counter-clockwise to increment the date (Fig. 2). The date disc begins to advance after a few turns of the crown, which is not a technical mistake, but by design.
Please note that the date should not be corrected between 21:00 and 3:00 in the morning, because the automatic date switch is already in process. A manual adjustment during this time may damage the mechanism.
This is especially observed when the watch a long time has not been worn and is stopped. In this case, first by turning the crown (clockwise) move the hands / time and make sure that the Calendar Attendant further switches / Midnight at 24:00 clock. If it goes further, you should imagine the hour hand still until 3:00 clock and correct until (= outside the automatic switching phase) the date by turning the crown counterclockwise manually.
Do not forget: To prevent the penetration of moisture, the crown must be again pressed down firmly against the housing when the setting is complete with the crown pulled.
1 Crown for winding the watch, and for correcting the minute-/hour-hand and to correct the date. 2 Minute hand. 3 Hour hand. 4 Seconds hand. 5 Date window.
The properties of the BUREN “Calibre 82”
The former of the chief engineer and technical director of the manufactory BUREN, Hans Koeher, described in his celebrated contribution to the magazine “Classic watches’ quality characteristics of the” Calibre 82 “had not only in 1971, the year of production, but also still be valid.
Nevertheless, there may be individual works, not temporarily reach when wearing the watch due to lack of optimal conditions not mentioned by Hans Koeher or the ideal values. As the main reasons for that are eg temperature variations, external effects / impact on the case of a name for the plant which is particularly disadvantageous angle and uneven spring lift due to different motor impulses to the rotor.
If after running the plant (about 1 month) yield a constant deviation from ± 5 seconds per day, this can be corrected by an appropriate adjustment.
One would like to recommend to meet the BUREN-watch and her legendary “Calibre 82” not only with an embossed by quartz movement and atomic clock claim, but also with some leniency.
The care of the BUREN “Calibre 82”
The warranty and service support for all editions of Swiss watches in the Hans-Peter Schmitz-Dedert GmbH launched watches are made by a master craftsman. The service address can be found in the warranty and service certificate.
Please leave any service orders for the BUREN “Calibre 82” of the master watchmakers at Swiss Watches – run editions. There you are particularly familiar with the work of this watch.
Like any machine, even the fine mechanical automatic movement this BUREN-watch needs a bearing lubrication. Fine traces of high-quality oil reduce friction in the pivot bearings. Hardened and used oil promotes the wear and impairs the accuracy.
The exceptionally high oscillation frequency (36000/2 vibrations per hour) of the “Calibre 82” made for the transition region a special lubrication system required.
Despite the uncomplicated design and manufacture of this work, its relatively easy transition regulation and thereby justified long maintenance-free periods, recommended, due to its high value and its irrevocability every 5 years a precautionary check by a watchmaker of Swiss watches – Editions.
Although the housing of the clock was up protected to a water pressure of 5 atm because of the uniqueness of the work by the manufacturer, one should not carry the clock for safety reasons for swimming, showering or in the sauna.
Basically, That the water tightness or protection from moisture at a clock can not be assumed to be a permanent feature. Crystal, crown and seals are subject to wear and aging. As long as the housing a clock provides protection against moisture, depends largely on the nature of his stress. For example, after only one – usually not noticed – something heftigerem shock / blow to the crown, the seal will be damaged. Also strong temperature changes can affect the sealing material. It is therefore desirable to have each year TESTING precaution, whether the seals of the watch has not been damaged by any outer influences (mechanical or chemical).
Visible condensation under the glass is an indication for moisture to evaporate. Optimum protection against it only offers the regular review of the watch. A review of the water tightness leads the service department of Hans-Peter Schmitz-Dedert GmbH or any good specialty store through for you.
If you look at the BUREN “Calibre 82” as a collectible and never or only occasionally wear the clockwork every 3 months should be installed, so that the oil does not thicken.
