This 47mm blue and gray accented Swiss made watch features 18 ultra bright T100 tritium markers that will glow for many decades. A mix of green, blue, and orange tritium markers make it incredibly easy to tell the time in any lighting environment. To ensure uninterrupted service, the watch is powered by a reliable and accurate Swiss made Ronda 715Li quartz movement. The movement also features a legible date display between 4:00 and 5:00. A long-lasting, 10-year lithium battery ensures more time on the wrist and less time getting serviced. Constructed out of carbon fiber reinforced polycarbonate, this lightweight watch weighs in at only 3 ounces. The dial is well protected by a scratch-resistant sapphire crystal with an anti-reflective coating. When your adventure involves water, this watch is ready to accompany you diving down to 200 meters. While in the depths of the sea, the unidirectional ratcheting diver bezel with two tritium markers will help you keep track of elapsed bottom time.
