LUMINOX is »SWISS MADE« Quality for maximum demands on robustness and excellent readability. Each watch contains tiny self-luminous elements developed by the Swiss world leader in tritium lighting components. These luminous elements (borosilicate glass capsules) are firmly embedded in the hands, the hour markers and, if necessary, on the bezels of the watches. Whether in the morning twilight or while diving and even in complete darkness. The current-independent lighting shows the time at a glance - regardless of the lighting conditions, without being charged by daylight, without pressing a button. With your new Luminox wristwatch of the Bear Grylls Survival Chrono w. compass 45mm series and the model number XB.3741 the price/performance ratio is simply right.
