IsoBright by Armourlite Eclipse Blackout Watch with T100 Blue Tritium, ISO201


  • $445.50

Amourlite's IsoBrite Eclipse Watch, model ISO201 is a very rare T100 tritium illuminated, Blackout Designed watch with all these features: a lightweight polycarbonate case, a 10-year battery life, an ultra scratch resistant sapphire crystal, two tritium markers on the unidirectional bezel, and 200 meter (660 feet) water resistance.

The key feature, of course, is the ultra bright T-100 power Tritium gas illumination, four times brighter than the tritium used in Luminox and most other tritium watches.  The dial is brighter, easier to read and the Tritium will glow longer (up to 50 years) than T-25 watches.

The Armourlite IsoBright Eclipse Blackout Watch offered here, model ISO201 is the nearly identical twin to the Military version, ISO203MIL, also offered by Time4Tritium.  The difference? The ISO203MIL has the crown on the left hand side of the watch, near the 9 o'clock position.  The ISO201 has the crown in the conventional right hand side, near the 3 o'clock position.  Otherwise the two models are identical.
