In the 1960s, Tornek-Rayville beat out several better-known brands to win the contract to build the U.S. Special Forces' first combat dive watch. That focus on rugged reliability shines through in the TYPE 7B BLAKJAK GMT Watch. Based on a 1990s military timepiece, this rugged field watch has a highly legible black dial with white numerals and Super LumiNova-filled markers and hands. A DLC-coated stainless steel bezel inlay is engraved with 12-hour markings, rotating to keep track of a secondary time zone. At the same time, the day/date complication has both English day abbreviations and Roman numerals, the latter for when it's more important to know how many days have passed than what day of the week it might be. A Japan-made automatic movement powers the watch, which comes with three strap choices: a quick-change steel bracelet, rubber dive strap, and Maratac Mil Series black nylon strap.
