Che Tissot & Fils Automatic Watch Movement – 21 Jewels – Believed ETA 2550 Family – Marked 743 – With Crown & Stem

📌 Description

Vintage Che Tissot & Fils automatic watch movement. The movement is not marked with a caliber number, but based on the plate layout and the “743” marking under the balance, it is believed to be from the ETA 2550 family. (Reference only — buyer should verify.)

The rotor is signed: “Che Tissot & Fils – 21 Jewels”. Includes the crown and stem. No hour wheel is included.

When wound, the movement showed signs of running, and the balance moves freely. Due to age, it is offered strictly as a parts or project movement.
