This listing is for a Baume & Mercier / Frederic Piguet Caliber 21 movement being sold strictly for parts or repair. This is a vintage, high‑grade ultra‑thin movement used by many prestigious Swiss brands.
The movement is missing the stem and crown and has not been tested. The balance wheel moves freely with an air blower. It also appears to be missing the hour‑hand center gear. Everything is shown clearly in the photos.
Being sold AS IS for watchmakers, restorers, or collectors needing parts.
A full service is recommended due to age and long‑term storage.
The Frederic Piguet 21 (FP21) is one of the most iconic ultra‑thin hand‑wound movements ever made. Many prestigious brands have used the FP21 as a base movement, often rebranding it under their own caliber numbers.
Other brands using FP21 without rebranding:
