WHAT IS LUMINESCENCE MADE OF AND HOW DOES IT WORK?

Luminescence, the emission of light without significant heat, lies at the heart of a dive watches' ability to glow in the dark. This phenomenon occurs when certain materials absorb and store energy from external sources, then release it as visible light in low-light conditions. Dive watches commonly employ two types of luminescent materials: Super-LumiNova® and tritium.

WHAT IS SUPER-LUMINOVA®?

Super-LumiNova® is a photoluminescent material that absorbs and stores light energy, subsequently emitting it as a glow. This compound is strategically applied to the hands, hour markers, and bezels of dive watches. Bremont's Supermarine collection employ up to as many as 15 to 20 coats of Super-LumiNova®, providing a vibrant and long-lasting luminescent effect that stands the test of time.

WHAT IS TRITIUM?

In contrast, tritium gas tubes utilize a radioactive isotope of hydrogen to create a self-powered luminescent effect. Tritium-filled tubes are placed on the watch's dial and hands, continuously emitting a soft glow without requiring exposure to external light sources. While Bremont does not currently utilize tritium gas tubes in their Supermarine collection, they have played a significant role in the evolution of luminescent technology within the watch industry.

The journey of luminescent technology in dive watches spans decades, with continuous advancements pushing the boundaries of visibility in low-light conditions. Early dive watches employed radioactive radium-based luminescent material, which proved hazardous due to its toxicity. The subsequent introduction of non-radioactive compounds, like Super-LumiNova®, offered a safer and brighter alternative.

Bremont's commitment to innovation is exemplified in their Supermarine collection. By harnessing cutting-edge luminescent materials, Bremont has elevated the legibility of their dive watches to new heights. The Supermarine models incorporate the latest Super-LumiNova® advancements, ensuring an unmistakable and enduring glow that captivates even the most demanding of explorers.

Bremont's Supermarine collection showcases the meticulous attention to detail that goes into applying luminescent materials. The vibrant luminescence of Super-LumiNova® illuminates the rotating bezels, allowing for quick and accurate time referencing, while the bezel's luminescent markers enable precise measurement of elapsed time during dives. You can read about what to look for in your next dive watch and why they have rotating bezels in our previous articles.
