Hello all, I recently picked up the watch pictured below. I know that it is a 342 automatic dated to 1949 in a Dennison made solid 9ct case, ref 12308. When I tried to look this up on the Omega database I ran into problems because of the Dennison case reference. The only similar watches were the Tresor range. These are solid gold, date from 1949 onwards, did have the 342 movement, among others, and the case styles are very similar, have a look at Omega cases 2643 or 2659. I know Tresor were usually 18 or 14ct but were Dennison asked to make a 9ct version in the UK? Tresor watches don't seem to be marked as such so what would set apart a Tresor as opposed to any other Omega watch? I am really happy with the watch, runs like a charm, just trying to get as much info together as I can so anything anyone else can offer about these early bumpers is gratefully received. Thanks.
