Seiko Marinemaster Professional Automatic 1000m. With a single piece Titanium case with TIHC hardened coating, anti-reflective sapphire coated crystal, and classic rubberized bracelet with Titanium buckle, this is one way cool watch. Unfortunately, it's a "Japan only" model, meaning it's not available for sale outside of Japan. At over three grand, it's a moot point anyway. For me, at least. Neat watch, though.
