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.

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.
