I found a decent 176.007 at a local pawn shop. Not mint but attractive, wearable, recently serviced and priced right. Anyway, the bracelet clasp isn't stamped with a reference. My understanding is that these originally came on 1170/653 and the modern OEM replacement would be 1162/172. I've also found some old threads that indicated that 120 end links were also original, though less common than 653. Mine has 120 on the end links. So what are your thoughts, is this bracelet original and legit?

 

The 120 endlinks were an option. I believe the bracelet is an american produced Omega bracelet (given the 12 on the clasp).

 

Thanks, based on this I've just spent the evening researching US produced Omega bracelets and it seems that these "no. 12" clasps are common enough that I feel comfortable that this is original to the watch. Thanks again!

 

This is the exact bracelet that my 176.007 has... same exact markings on the clasp and the end links.
Awesome pick up.
Wear it in good health.

BTW, dose anyone know which bracelet this one is as it is missing the reference marking? is it american produce 1170 equivalent? what is the exact reference number?
Any info would be much appreciated.
