Armourlite Operator Series Tritium Watch Black/Black/White 43.5mm. By combining our shatterproof Armourglass crystal with a carbon fiber reinforced case we have achieved a watch that is both ultra tough and ultra lightweight. To easily tell the time in any lighting environment the watch features 14 green and orange self-powered tritium markers by trigalight. For the ultimate protection of the dial the shatterproof Armourglass crystal can withstand up to 6000 Vickers whereas most watch crystals can only withstand about 700. Using the same technology as bulletproof glass we have achieved a crystal that wont shatter even when one layer is compromised. This crystal was previously only available in our ArmourLite watches with a stainless steel case. To ensure uninterrupted service the watch is powered by a reliable and accurate Swiss Made Ronda 515 quartz movement. The movement also features a legible date display at the 3:00 position on the dial. For the underwater explorers this dive-friendly watch offers a water resistance of 100 meters (10 atm). In addition a 60-clicks unidirectional ratcheting diver bezel helps keep track of elapsed bottom time when diving.
