Calibre 1001
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 might give an idea. Small by today's standards, of course.
FWIW I know that style of hands as "bâton". Cathedral style was named for a resemblance to church stained glass windows, with open segments often filled with enamel or luminous material.
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 unle...
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 ...

I was quite excited by the Ref 6984
A clever design to accommodate the larger automatic movement while still looking like a classic dress watch. ...
Ok but does not compare to Alex's Wedding Cake dial VC ...
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?
Thank you for sharing.
This is a learning garden for vintage VC's enthusiasts. I find a variant of ref 6627 ...
I don't understand the size of the movement
7’'' 17 - 24 I guess 7’'' is the length of the movement What does 17-24 mean? ...
Systems for measuring movement size and thickness
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...
the calibers on book 《The World of vacheron constantin geneva》,
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
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.
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
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 for sharing.
Today is the fifth day of the Chinese New Year. I hope health and wealth will be with you.
Thank you very much. A really comprehensive post on VC tonneau shaped case.
I looked at every picture and narrative, trying to find the ancestor of my historique 1912, but still unsure. Which one do you think? ...
Perhaps it is an interpretation
Rather than an direct copy. After running through the more extensive World of VC reference photos, I cannot find an exact match for the lugs. Photo #908 comes closest in terms of shape and date. World of Vacheron Constantin ...
