ArmourLite IsoBrite Eclipse Tritium Watch

ArmourLite IsoBrite Eclipse Tritium Watch

The ArmourLite Isobrite Eclipse belongs to the latter. This is the kind of watch you strap on when the lights go out, the weather turns sour, or the plan changes—and you still need to know exactly where you stand in time.

Built like a piece of issued kit and finished with quiet confidence, the Eclipse is powered by ArmourLite’s legendary Isobrite tritium illumination—a steady, self-powered glow that doesn’t ask for sunlight, batteries, or permission. Day or night, desert or deck, blackout or backcountry, it’s always readable. Always on.

The case is tough without being loud, purposeful without pretending. The sapphire crystal shrugs off abuse that would leave lesser watches crying in pieces, while the 200 meters of water resistance means rain, surf, sweat, or bad decisions won’t slow it down. This is a watch made for people who value reliability over flash, clarity over complication.

The Eclipse doesn’t care if anyone notices it. It’s not here to impress. It’s here to endure.

To easily tell the time in any lighting environment, the watch features 18 self-powered tritium markers by trigalight®. These are the same constantly glowing tritium markers that are used in weapon sights.

For the ultimate protection of the dial, the shatterproof Armourglass crystal can withstand up to 6,000 Vickers, whereas most watch crystals can only withstand about 700. Using the same technology as bulletproof glass, we have achieved a crystal that won’t 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 715Li quartz movement. The movement also features a legible date display at the 4:30 position on the dial. In addition, a 60-clicks unidirectional ratcheting diver bezel helps keep track of elapsed bottom time when diving.

Key Features

• SWISS TRITIUM ILLUMINATION: ArmourLite watches have tiny glass tubes that are filled with tritium gas and then hermetically sealed. The electrons of the gas continuously react with phosphorescent paint resulting in a radio luminescent light source that glows constantly for several decades. No external power source or charging-by-light is necessary to maintain the glow. The glow is completely self-powered.
• SHATTERPROOF ARMOURGLASS: The watch is protected by shatterproof Armourglass crystal that can withstand up to 6,000 Vickers, whereas most watch crystals can only withstand about 700. Using the same technology as bulletproof glass, we have achieved a crystal that won’t shatter even when one layer is compromised
• SWISS RONDA MOVEMENT: The watch is powered by a reliable and accurate Swiss-Made Ronda 715Li quartz movement with a battery life of 10 years. Ronda is one of the most respected makers of quartz movements and strictly adheres to an ISO 9001 quality control system to ensure that every movement meets the most rigorous standards.
• ULTRA LIGHTWEIGHT: The watch features an ultra lightweight and extremely durable carbon fiber reinforced case with a diameter of 43.5mm. The double-gasket push-in crown on the right side of the case is protected by two side shields. For keeping track of elapsed dive time, the case has a unidirectional ratcheting diver bezel.
