Tick Talk, a respected voice in the WatchProSite community, delves into the fascinating history of Vacheron Constantin's tonneau-shaped wristwatches. Inspired by contemporary releases like the Harmony and American 1921, Tick Talk unearths vintage examples, providing crucial context on Vacheron Constantin's historical numbering systems. This deep dive offers invaluable insights for collectors seeking to understand the lineage of these distinctive timepieces.
By The Numbers
Vacheron & Constantin employed three formats over the years to identify timepieces: photo reference numbers, catalog numbers, and model reference numbers. From 1904 to 1937, V&C photographed certain watches of interest and assigned them photo reference numbers in sequence from 1 to 3800. These were internal identifiers, unrelated to the catalog numbers used in printed materials for dealers and customers.
Photo reference were superseded in 1938 with production-based model reference numbers, commencing at 4000. Note, however, that series 5000, 8000 and 9000 were not used. Until 1950, model reference numbers were used for internal purposes and were not inscribed on timepieces. After 1950, model reference numbers replaced catalog numbers and were inscribed on the inner case back, along with hallmarks and case serial numbers.

The Patek Philippe Calatrava reference 5000, introduced in 1996, is notable for its distinctive asymmetrical dial layout, a departure from the more traditional Calatrava designs. This reference features a small seconds sub-dial positioned between 4 and 5 o'clock, giving it a unique aesthetic that sets it apart within the Calatrava collection. It represents a period of design exploration for Patek Philippe, offering a contemporary interpretation of their classic dress watch.
The watch is housed in a 33.4 mm case, available in 18k yellow, white, or rose gold. It is powered by the ultra-thin self-winding caliber 240, known for its integrated micro-rotor, which allows for a slender profile. This movement provides a power reserve of 48 hours. The watch is fitted with a sapphire crystal and offers water resistance up to 30 meters.
For collectors, the reference 5000 is appreciated for its limited production run and its unique dial configuration. It appeals to those seeking a Patek Philippe Calatrava with a less conventional design while retaining the brand's horological integrity. The various gold variants, including the 5000G (white gold), 5000J (yellow gold), and 5000R (rose gold), offer collectors choices in case material, each contributing to the reference's distinct character.
I love the minimalist design of the ref 6589 produced in 1961. Do you have more details (size, 1001 movement) I also like the "cathedrale" hands ;-) All the Best, Patrick
Thanks Patrick The 1001 is a very elegant movement with classic finger bridges, introduced in 1951. Based on the JLC 818 ebauche, it measures 9 lignes across with a height of 2.94mm. 18,000 vph and 17 or 18 jewels depending on variant. The one pictured here, bearing the Geneva Seal, has both Gyromax balance and Kif-flector shock protection, perhaps the ultimate evolution. The Calibre 1002 was a development of this movement with centre seconds. As far as the case size, this image from the web mig
A clever design to accommodate the larger automatic movement while still looking like a classic dress watch.
Any chance you can post that beauty on the Front Page where these are posted-please?
there is no logical connection here, nor with Front Page as far as I can see. You have such a deep interest in this one piece, perhaps contact Alex directly?
Hard to believe it's going nowhere
