Lightweight Automatic Watch with T100 Tritium Markers

This 44.5mm Isobrite Squadron Series watch features 16 ultra bright T100 tritium markers that will glow for many decades. A combination of green, ice blue, and orange tritium markers makes it incredibly easy to tell the time in any lighting environment. The 12:00 position is even more noticeable with a photoluminescent glow-in-the-dark triangle with 2 dots.

To ensure uninterrupted service, the watch is powered by a reliable Japanese NH35 mechanical movement with 24 jewels and a date display. The movement features both manual and automatic winding, as well as a power reserve of about 41 hours.

Constructed out of carbon fiber reinforced polycarbonate, this lightweight watch weighs in at only 2.7 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 60-click unidirectional ratcheting diver bezel with a tritium marker will help you keep track of elapsed bottom time.
