Timex Expedition Pioneer Titanium Automatic

TW2Y63600 / TW2Y63800

The Expedition Pioneer Automatic is the dive-bezel sibling of Timex's Pioneer GMT: the same 41 mm barrel-shaped titanium case, but with a unidirectional ratcheting bezel marked for elapsed time, which makes it a proper diver. The case and bracelet are Grade 2 titanium, 13.5 mm thick and 48 mm lug to lug, with 200 m of water resistance and an anti-reflective sapphire crystal. The black dial is sand-blasted metal with a date window and lumed hands and markers. A Miyota 8215 automatic runs it, visible through an exhibition caseback, and the bracelet has quick-release spring bars for swapping to the rubber strap Timex also sells it on. On the titanium bracelet it lists at $579.
