Tritium-filled gas tubes give this lightweight diving watch unrivaled visibility in the darkness.
Traditional photoluminescent compounds — even the gold-standard Super-LumiNova — require light to charge the paint before it will glow. Unsatisfied with this solution, the founder and former owner of Luminox Watches returns to the technology he pioneered beginning in 1989, a self-powered lume that involves filling micro gas tubes with tritium gas. The resulting glow lasts for decades, is 100X brighter than conventional photoluminescent lume, and is the signature feature of his ProTek brand of watches. The PT1001 Carbon uses it to light its hour markers, hour, minute, second hand, and bezel pip, making the watch visible in any light condition including complete darkness. Its 42mm case and tight 60-click unidirectional timing bezel are crafted from carbon composite, with a 316L embossed stainless steel screw-in caseback and crown. It's powered by a dependable Miyota quartz movement with a 10-year battery, has a date window at 3 o'clock, and sits on a genuine rubber strap with a signature steel buckle.
