Make sure the clasp is suitable for the environment you will be wearing it in
Color: G9901: Black band & Black dial
I don't know if I didn't look closely at the clasp pick, or if I just didn't see one, but the clasp is a bit weakly designed for everyday wear. It's come unclasped twice in the 2 weeks I've been wearing it
