Vacheron Constantin 1136

Caliber 1136 is an automatic chronograph manufactured by Vacheron Constantin. Introduced in 1990, it features a three-register layout for elapsed time measurement and is based on the Piguet 1185 movement. Though based on an external architecture, the caliber served as the chronograph platform for several Vacheron Constantin models in the 1990s and early 2000s before being discontinued.
