My Dad gave me my Great Grandfathers watch for my wedding. It looks like an Omega Marine but in books and online I cannot find a similar watch that has both Omega and Tissot logo on it. The inside of the case reads:
1st line - Tissot
2nd Line - Swiss
3rd Line - Strybrite
4th Line - BTE + 146310
5th Line - BTE S GDG 710316
6th Line - British Pat 365356
7th Line - U.S.A. Pat 1907700
8th Line - D.R.P. 567213
9th Line- 684441
The strap is not the original, but can please give me insight on what I have. I feel like it's rare or counterfeit.

 

Thanks! Do you know the range of value? Not looking to sell, but want to know if it should be locked up or if I should only wear on special occasions. Pretty much want to know what I'm dealing with, I'm a novice at this.

 

Nice watch. Congrats.

Mine says hello :

 

looks like the read deal there!!! congrats and enjoy. Do you still have the original deployant clasp? those are not available anyway...

the other interesting thing is the straps... originally, these came on seal skin straps.

I'm assuming it's not waterproof anymore... anyway, still very very nice!
