Just saw it, or them, thanks to a give away A Blog To Watch is having.
Seems like the watch has a Ploprof-like feel, along with 50mm stainless steel
case, 2000m WR, a single domed sapphire crystal, helium escape valve, black
dials with luminous hands, and markers. Plus black, or orange aluminum bezel
inserts, stainless steel bracelets, and Seiko NH35 automatic behind nice case-
back.
A few pics for you...
