It's a little hard to date this one because it doesn't have a serial number inside. Seller said it was 18k and it does have the French early 18k mark in the middle of the case back.

There are lots of watchmakers service dates inside the case that look like they might date to the 1940's but since it has Geneve on the dial I would assume it's from the early fifties. I was wondering when 18k was implemented as the gold mark vs some of the earlier methods. That might help date it. The movement is marked Breitling and is running but is dirty and will need a good service and the case has wire lugs which require an open end strap so it might be an earlier piece. Also have a new strap on the way as this one is in the trash already.
