Baume & Mercier BM13750

The BM13750 is a chronograph movement based on the legendary ETA/Valjoux 7750 caliber, one of the world's most widely used automatic chronograph movements. Features day and date complications alongside the chronograph functions with 12-hour, 30-minute, and running seconds sub-dials in the classic tri-compax layout. Used in various Baume & Mercier chronograph models. Due to ETA restrictions on non-Swatch Group brands, newer chronograph models may use alternative movements.
