60’s Seamaster Cosmic Original box

Wetworks

I'm a bit of a Cosmic fan, and I can't ever remember seeing that kind of Cosmic dial (sparkle, I like). Got any more pics of the watch?

As for the bracelet, I used to have mine mounted to an 1173 with straight links, but you can mount it to any strap. I forget if the lug width was 18mm or 19mm, but I would lean towards the latter. Boxes are tough to source sometimes. I have one for my Seamaster from this era, but that was a birth year watch and was the only reason I even bothered.

I just bought it going to change the strap, unfortunately didn’t have have the box hence the post. Absolutely love it. It’s been worn, as it should be, abs that shows on the case back but what do you expect after years

Are you looking for an Omega branded NOS strap? If so, that's going to be a tough find for this model/era.
There are a number of reproduction straps available (a few even listed here on OF in the sale forum) that look very similar to original straps that these were originally fitted with when new, that you could pair with a vintage OEM buckle.
