Here's one that comes up from time to time. Likely you know all about it, an understated tool watch. Just in case though here's a bunch of information.

Comes with box and papers, plus an open warranty card from watchmann. Seldom worn, condition is excellent. There are no marks I can find as might be expected considering the case hardening and sapphire. $1150
