Vintage Vacheron Constantin used a wide range of hand‑wound calibers over the 20th century, and any list will be partial rather than truly complete. The calibers below focus on classic, time‑only, hand‑wind movements collectors most often encounter in vintage dress pieces.
After much searching, I have finally got this 35mm Vacheron in Stainless steel.
1940s–1960s standard manual
• Cal. 453 (sub‑seconds) – manual, time‑only, based on a Jaeger‑LeCoultre ébauche, widely used from the 1940s into the 1960s.
• Cal. 454 (center seconds) – manual, time‑only, center‑seconds version of the 453 with a thicker mainplate to support the extra gearing.
• Cal. 1007/BS (sub‑seconds) – chronometer‑grade, manual, essentially an uprated 453 for Chronomètre Royal, with hacking (balance stop).
• Cal. 1008/BS (center seconds) – center‑seconds version of the 1007/BS with similar chronometer‑oriented upgrades and hacking.
Thin hand‑wound calibers
• Cal. K1001 – thin, manual, sub‑seconds, produced from the 1950s into the late 1970s, derived from a dedicated Jaeger‑LeCoultre base for Vacheron Constantin.
• Cal. K1002 – thin, manual, center‑seconds variant of the K1001, with an extended gear train for the central second hand.
• Cal. K1014 – later thin, manual sub‑seconds movement (about 1970s onward), simplifying the K1001 bridge layout while retaining a slim profile.
Ultra‑thin hand‑wound
• Cal. 1003 – ultra‑thin, manual two‑hand movement (hours and minutes) originally based on the JLC 839/849 family, around 1.64 mm thick and historically one of the thinnest hand‑wound movements ever made.
