Ladies' Éye (bauche) for the Horological Guy: c. 1055

In a number of discussions and  articles in The Hour Lounge and elsewhere, I keep finding that the Vacheron Constantin caliber 1055 is used in the ladies' version of several watches. However, in the men's version of the Vacheron Constantin 1972 Asymmetric the c. 1055 is used as well. Indeed, the watch is smaller than some of the other men's watches, but I take it to be an evolutionary pattern. My 1972 seems to fit me quite well, and the time it keeps is spectacular.

1972 Asymmetric on the Wrist

This may seem a bit small for the larger wrist of say, a Neanderthal or gorilla, but it fits me just fine. The small ébauche is no doubt due to the narrow (26 mm) of the watch. In fact, the c. 1055 is the smallest mechanical movement that Vacheron Constantin makes (as far as I know.)

This photo of my c. 1055 was taken though a loupe to give it a larger (more manly) appearance.

Caliber 1055 in 1972 Asymmetric

I consider the watch and its calibre as an evolutionary phenomenon, and I can imagine that earlier models of the human kind looked forward to the next steps in the evolutionary ladder.

Apologies to 44mm watch-wearers.

Love it

The honor of "smallest" VC movement currently available belongs to the 7-ligne 1005 bagette, which is also the caliber with the longest production history.  Although no longer offered by VC, the 1055 was based on the 7-ligne Frederic Piguet caliber 6.10 introduced in 1993.  Before this, V&C had several 7-ligne movements based on JLC ebauches; the cal. 446 tonneau, 1426 round, 1005, and 1050 cushion-shaped.  Smaller still was the diminutive 5 1/2 ligne backwinder caliber 446!

Love it

Mrs TT enjoys the 6.10 in her Daniel Roth lady's watch and it was most popular for those very small cases.  One reason VC may have selected it for the MCMLXXII was thinness; as you can see there is still plenty of space for a larger movement but with small also comes skinny, which complimented the slim lines of your watch.  While it is true the 9-ligne caliber 1003 was thinner, it was also more limited and expensive.  Regardless, the 6.10 has withstood the test of time and is well appreciated by the brands that used it.

Love it

As one with skinny wrists, I share your preference for the smaller cases.  You will find many wonderful vintage V&C pieces that may also suit your palette.

Love it


Great-looking vintage VC

That Vacheron Constantin looks great on your wrist.

I love smaller movements which are also used in ladies' watches.

Cal.1055 is right size and it operates at good frequency.

I didn't know you're a poet! ...She beats in beauty,... nice one.

By the way, it turns out that my MCMLXXII may not be so small after all. It was made in 2000, and compared to my 1991 Audemars Piguet  mens Day/Date Moonphase, it actually looks bigger.

With my penchant for placing flying saucer-sized watches on Neanderthals and gorillas, I neglected to point out that the calibre 1055 is also on Vacheron Constantin's Heures Créatives line of striking ladies' watches. My favorite is the Heure Discrete (ref. 37530):

It is nice to see a line of ladies Vacheron Constantine watches that include a mechanical ébauche rather than one with a quartz-based movement and an Ever-ready bunny hopping around inside. (If you pronounce "quartz" in a similar key as the word "croak" it sounds more appropriate in this context.)

I didn't know, thanks smiley.  Long live the 1055, although with VC's stated goal of all inhouse movements I wonder how much longer it has?

At the prices for the collection pieces, it may be a while. Like the 1311 (GP) and 1055 (Piaget?) I like to think of these ébauches as adopted and part of the VC family. Sort of a Prince and Pauper story....

When VC presented Heures Creatives collection last year,

I was so surprised to know cal.1055 is still used.




LOL :-)

They LITERALLY advertised the new Navitimer as simply "Now Bigger".  Made me laugh a bit.  Apologies to anyone who likes modern Breitlings.

Too funny.

I actually thought you were going to discuss their target demographic.  Nope.  I do get that different folks like different watches, but when the actual offered value proposition is simply that it is now larger, I have to shake my head a little.  I now know who the go-to member is for photoshop work.
