This escape wheel is a generic aftermarket replacement for the Vacheron Constantin Calibre 1137 and the Frédéric Piguet 1185 automatic chronograph movement (part number 1180‑30.040.L). As the last wheel in the gear train, it delivers precisely timed energy impulses to the pallet fork, regulating the escapement for accurate timekeeping. This steel component is ideal for restoring original chronometer performance when the original escape wheel is worn or damaged.
Cross‑caliber compatibility – Fits VC 1137, FP 1185, and other 1185‑based movements (e.g., AP 2385, Blancpain F185).
Precision steel construction – Durable, wear‑resistant, and anti‑magnetic.
Escapement accuracy – Ensures stable amplitude and precise rate regulation.
Drop‑in replacement – Exact fit for the original escape wheel, no modification required.
Cost‑effective alternative – Affordable solution for servicing high‑end chronograph calibres.
