In my opinion this movement is not JLC produced.

This is, indeed, a JLC (LeCoultre) 493 movement from around 1953 (based on the serial number). This movement was introduced in 1951 and was the first rotor-based automatic caliber produced by JLC. It's a 9 ligne (20.3 mm) automatic movement running at 18000 BPH with glucydur balance, Nivarox hairspring and Kif-Protechoc shock protection. Based on the import code on the balance bridge, VXN (Vacheron Constantin - LeCoultre), this movement would have been placed in a U.S.A. market watch.

Hi Jimh,
Thank you very much for your extensive informations.
At a first glance it looked to me rather primitive, beeing a cheap movement of the "dark JLC times" produced by A.Schild or somebody else.
