Name: Blancpain 1185 Fifty Fathoms Tech (or related 1185-based model)
Brand: Blancpain
SKU: 1185

Ref. 1185

The reference 1185 is associated with Blancpain’s historic **Cal. 1185** movement, a groundbreaking automatic chronograph caliber introduced in 1988. This movement was renowned for its **3Hz frequency (21,600 vibrations/hour)**, **40-hour power reserve**, and **vertical clutch column wheel**, enabling continuous chronograph operation without draining the power reserve. The 1185 was a precursor to the legendary **split-seconds chronograph (Cal. 1186)** and became a benchmark for high-end watchmaking, later adopted by brands like Audemars Piguet and Cartier. The movement’s technical sophistication and durability cemented its place in watchmaking history.
