Automatic watches were hot in the 1950s, and chronographs were cool in the 1960s. But bringing these technologies together was not at all straightforward! Three different automatic chronograph movements were launched in 1969, and the story of their creation reflects the state of the industry at that time as well as the inevitability of technological progress.
I’ve got a thing for classic dress watches in general and Patek Philippe Calatravas in particular, so I get excited when I see a real classic come up for auction. Such is the case with this Ref. 5015 Moon Phase Power Reserve: It’s not technically a Calatrava, but it features all the best elements of that line. Starting at just €7,000, who’s bidding?
Continuing my quest for the perfect Patek Philippe Calatrava, I turn to the other main branch of the family. In 1973, Patek Philippe added “Clous de Paris” guilloche to the bezel of a straight-lug Calatrava and a new legend was born. Today, many people think of this Ref. 3520 rather than the clean, flowing original when they hear the name! Is this the perfect Calatrava?
