Best of The Hour Lounge: Vacheron & Constantin Tonneau Wrist Watches

Inspired by the Harmony watches of fellow Vachonistas and the piece unique American 1921 recently introduced, I've reached into the vault for this feature on shaped watches. But first, an explanation of model numbers.

Image credit Vacheron Constantin unless otherwise noted.

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Photo reference were superseded in 1938 with production-based model reference numbers, commencing at 4000.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.

Great post Dean +++++

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 ...

Calibre 1001

By: Tick Talk : May 29th, 2021-15:29

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 he...

A clever design to accommodate the larger automatic movement while still looking like a classic dress watch. ...

Thanks for a terrific and very informative writeup Dean, always a pleasure to learn from you on all things Vacheron! I cross-posted it to "Editors Picks"👍

Any chance you can post that beauty on the Front Page where these are posted-please?

This is a thread on tonneau shapes

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?

OK...I have spoke with Alex

Hard to believe it's going nowhere

Excellent! Good to see the movements, too. I didn't know green gold existed!!!

I don't understand the size of the movement

By: teacher Sun : May 30th, 2021-03:01

7’'' 17 - 24 I guess 7’'' is the length of the movement What does 17-24 mean? ...

By: Tick Talk : May 30th, 2021-16:18

Great question but I can only give you a partial explanation of the movement descriptions for these shaped calibres. There were industry conventions to describe movement sizes and we are all familiar with the ligne of 2.256mm used to indicate the width of...

page 409. "movement in use until date indicated", I must to make sure about the exact meaning of this statement. Whether to describe the time when caliber stopped producing, or when it stopped using.Its important because I found a new model . How do you t...

My reading

By: Tick Talk : February 1st, 2025-15:01

Is that the movements were in production until the dates noted. But I wouldn’t take their information as a certainty, knowing as we do how V&C often repurposed old stocks long after production ceased.

So my initial understanding was wrong.

By: teacher Sun : February 1st, 2025-21:34

English is not my native language, which makes it difficult for me to read and study. this model sold by artcurial, case shape looks like photo ref.3793. the 7"' caliber were in production until 1938, but consider case number, it was still use until early...

And of course

By: Tick Talk : February 2nd, 2025-05:13

in the days before internet, influencers, and other marketing efforts made VC products available to a worldwide marketplace, V&C sometimes had to wait years before a buyer came into a boutique and spotted a watch they had to have. It was particularly chal...

Thank you very much. A really comprehensive post on VC tonneau shaped case.

Perhaps it is an interpretation

I think you have a point there as i still couldn’t find a close enough ancestor.
