Dear OF,

I’ve owned this 1967 manual wind 33mm diameter 9 carat watch for some time but would appreciate your expertise on deciphering the snap on caseback, particularly the following markings;

DS & S
Baume (as in why is Baume stamped in a Longines caseback) and
63880

Thanks in advance of your responses

 

Baume was th importer of Longines in England and DS&S ( David Sutton & Sons) is the case manufacturer.

 

Thanks, I didn’t know that
