Master Carbon SEAL Automatic 45 mm, Military Dive Watch - 3875 The Master Carbon SEAL Automatic combines all the details for which Luminox is famous – toughness, luminosity, extreme water resistant, legibility – with a Swiss Made SELLITA SW 220-1 automatic movement that also features a day and date window.For the first time, Luminox is introducing an automatic movement in a CARBONOX™™+ case, which is three times lighter than titanium. There is always something special about a mechanical movement, the way the pieces and parts come together to bring the movement alive, the balance wheel turning and driving the hour and minute hands. Reliable and tough, this automatic movement is a joy to watch in motion.The bezel of the Master Carbon SEAL Automatic is stainless steel with an IP black plating, and the bezel markings are in a very cool steel color. Of course, the Master Carbon SEAL Automatic is equipped with our Luminox Light Technology, making sure the watch is totally visible in low or no light conditions, never having to rely on an exterior light source.
