Omega Tissot Ref CK 679 Help

DHKNOLA · Sep 6, 2022

I won this off ebay and have gotten the message that it has passed authenticity from ebay. I went to get Omega.com to obtain the extract and it seems the movement serial does not have enough numbers for Omega.
Here is the watch, can anyone help me out with where the seven digit serial would be?

Thanks in advance,

Have you checked the Tissot serial numbers charts? https://millenarywatches.com/tissot-serial-number/

It's a Tissot movement. Caliber 27 I think, which shares some parts with the Omega cal 26.5.

I'd like to see the markings inside the case back.

That's because your watch is a Tissot, not an Omega. Both Tissot and Omega produced the "marine" in the 1930s, with the Tissot version using the double-signed Omega-Tissot brand. The Tissot movement is a caliber 19.4, commonly used in their ladies watches from that era.

Another Tissot marine is shown in this thread: https://omegaforums.net/threads/omega-marine.16385/
