Lemania 2320

The Lemania 2320 is a refined variant of the legendary 2310, featuring a swan neck regulator and 4 additional jewels (21 total). This higher-grade version was developed for premium watch applications and served as the ebauche for chronograph movements from prestigious manufacturers including Vacheron Constantin (as Caliber 1141/141/141q), Breguet (as 533.2), and others. Like the 2310, it features column wheel chronograph control and the distinctive 'wishbone' bridge design.
