Tritium overload best describes this new 64-tube Swiss Made T100 tritium automatic watch by Isobrite. It is a masterpiece of colors, design, and function. There are 60 tritium tubes on the dial to mark each minute/second, 3 tubes on the hands, and one tube on the unidirectional diver bezel to keep track of elapsed time.
Equipped with a reliable and proven ETA 2824-2 Swiss automatic movement, the watch does not need a battery to power the movement or the illumination. Constructed out of 316L stainless steel and protected by a scratch resistant and anti reflective sapphire crystal, this watch feels solid, rugged, and utterly comfortable.
From dressy to diving to night activities, there is no need to swap out watches. Moreover, the screw down crown ensures a water resistance of 300m (990ft), perfect for diving into the deep. The watch also has an exhibition caseback to allow you to enjoy the workings of the mechanical movement.
Why do T100 watches last so much longer than T25 watches?
The Isobrite T100 watches contain approximately four times the amount of tritium gas as the T25 watches do (i.e.: Luminox, Traser, MTM). The higher volume of tritium gas results in a much brighter visible illumination combined with a much longer life span of illumination. The Isobrite T100 watches will have a life span that is approximately twice as long as the T25 watches. Plus, at 25 years the T100 watch will have the same visible illumination that the T25 watch started out with. By that point the tritium in a T25 watch would have become fully decayed and barely visible. On the other hand, the T100 watch will continue to glow for approximately 50 years.
