Ultra Bright T100 Tritium Markers in a 39.5mm Midsize Case

At 39.5mm in diameter, this Swiss Made midsize watch is the smallest model we’ve ever made with the ultra-bright T100 tritium markers.

The watch features 28 ultra-bright T100 tritium markers that will glow for many decades. A combination of green and orange tritium markers makes it incredibly easy to tell the time in any lighting environment.

To ensure uninterrupted service, a reliable Swiss Made Ronda 505 quartz movement powers the watch. The movement also features a legible date display between 4:00 and 5:00.

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 a tritium marker will help you keep track of elapsed bottom time.
