Unknown caliber

Hello, can somebody please inform which caliber is this and if it has interchangeable parts with any other known caliber?

It has a stamp with the no 1340 on the dial side.

Thank you in advance


This is a movement made before the 1938 JLC and VC "joining"

It has been the topic of a few recent posts, though I don't know its official calibre # (or if it even has an official cal. #).  It should have been made in the 1930s.



Did you notice the import code?

Appears to be "VXC" engraved on the balance cock, definately not VXN.  But according to Pritchard's there wasn't such code; VXB, VXN, VXO, VXT, VXX and VXZ.  Maybe a badly imprinted VXO which was for Transit, a maker entirely unknown to me.  I suspect these ebauches were provided by outside suppliers, if only for the non-V&C 4-digit manufacturer's serial number engraved on the back side.  Yours is #1340 and the earlier post "V&C Tank" featured #1280.   See my reply there for more discussion of tonneau movements.


Seems as VXO to me :) (nt)

Transit Watch Co. Ltd. was a Swiss ebauche maker that has mostly disappeared from the historical records.  The few examples I've found were good quality form calibers for ladies watches sold under private label.

the last movement has import code LOZ, which is non-existant according to Swiss Timepiece Makers 1775-1975.  Time for an aspirin indecision
