Jurry's recent post highlights the exceptional long-term performance of his Vacheron Constantin perpetual calendar chronograph, showcasing its remarkable accuracy after three months on a winder. His experience underscores the enduring precision and reliability expected from high horology, even when a timepiece is not in daily wear. This discussion delves into the specific movement powering such impressive results and the broader context of Vacheron Constantin's horological prowess.

the base Lemania 2310 that is. Aside from VC, it was a stalwart for Patek, Breguet, Dubuis, Omega and many others. FWIW, Richemont obtained the rights to produce the 1142 version back in 2008 with its acquisition of Roger Dubuis. Dubuis also routinely had these chronographs certified at Besançon Observatory so clearly they were capable of great timekeeping! Wei Koh documented the fantastic history of this movement, posted at Revolution and worth checking out.
and your collection..lol This watch and your 1921 are on the top of my grail list! Thanks for sharing -D-
I’m glad you like them so much. The 1921 is a special model as well. So much character and history that makes it unique. I mean most brands feature a perpetual calendar chronograph with moon and many of them were based on the same Lemania movement. But that 1921 is something only at VC So yes I agree it is a great brand. Thanks for looking
