Hello again! Finally own another Speedmaster again after looking for a decent deal on one. Found a great example and am loving it already. C
Are seems to not have been polished and runs great so far all day today.

The only thing puzzling me is the bracelet and clasp. Omega logo on the clasp exterior, nothing on the endlinks though and the inside of the clasp is...lacking...on info. Possible it’s a later service bracelet? Or a fake? Would love your opinions...pics attached!

 

Congratulations for your Mark II!
That should be a holzer bracelet. These were used to be made in Mexico.
The clasp exterior looks good to me, but the interior should have a j/m engraved.

Ah! Thank you for that! Makes total sense as I did purchase it from someone in Mexico City. There is no J/M or other markings in the bracelet though. I’m going to see is I can find any other silliest iterations now that you’ve pointed me in a good direction!
