I'd like to know what bracelet reference this is. I think I have the endlinks somewhere, but the bracelet is not signed.

 

I posted a similar inquiry a while back:

The No. 12 stamp seems to indicate that it is a US produced model. I have read elsewhere that these were pretty much exactly the same as the Swiss/European counterparts that were stamped with the correct bracelet reference. Yours is similar to mine (the equivalent of 1170) but the clasp design is slightly different.

 

Looks like mine. Not identically marked but No. 12. With help we determined it was a 1175, although Andy's looks similar too.

Looks similar to this BCT, for Seamaster --- using 19mm #48 end links?

 

Thanks for the aid, guys. Gives me a lot to go off of.
