Traser P67 Officer Pro Automatic Watch

Tritium is a radioactive isotope of hydrogen that glows in the dark for decades without exterior power. Though it’s not used too frequently in watches, it can make a serious difference for anyone who puts emphasis on legibility. That’s just what you get with the Traser P67 Officer Pro: a 45-millimeter automatic field watch built with the best of the best. Featuring tritium tubes in the hands and hour markers, plus large Arabic numerals at the cardinal hours, it reads easily day or night. The hour hand is thicker than anything else, and even the seconds hand has a small tritium tube at the end for visibility. A stainless steel case and sapphire crystal make for excellent durability—not to mention a water resistance rating of 100 meters.
