Edited, since it has arrived.*

So the bracelet that came on my new 145.022-74 is marked 1171 with an 11 in a circle. However the Omega logo on the outside is in a square, not a trapezoid, and the removable links have screws.

I was under the impression (mostly from searches here) that original 1171s always had the logo in a trapezoid.

My thinking is that only the clasp outside piece was replaced at some point. Thoughts?

That style of clasp is definitely on a Mark IV. Screwed links on an 1171 is ok.

I’m not sure when the trapezoid logo switched to square, but I’d say a -74 should have a trapezoid logo. It’s not a huge difference in value though so I wouldn’t worry too much

Thanks. This is evidently a very late production transitional - 74 that appears to have been made in the summer of 77.
