Mine clasp was is also stamped 93250 with round 3. The cornet looks decent. The bracelet is stamped 93150 but has a round 3. It feels nice though and cant see the numbering anomalies when on the wrist.
I'm wearing mine as i type. I had a folded link bracelet but decided to try a rep 93150 (from cartell) about 6 months ago and havent gone back since. Albiet more accurate (7836) the 93150 feels more secure and a bit beefier. Just my 2 cents... Enjoy your MC and looks fantastic!
