Nite watches feature a highly-specialised illumination technology called GTLS (Gaseous Tritium Light Source). Until recently this was only ever used in advanced military hardware or pioneering safety equipment, where a guaranteed light source was needed for safe operation in all hazardous environments and conditions. Fitted to watches, the result is a dial that can be read quickly and easily in all light levels and NEVER NEEDS RE-CHARGING from another light source. There's no fiddling about with buttons or worry about running the battery down; they will glow all night (and day, but you can't see it!) for a guaranteed 10 years - and typically last 20. Nite watches are Swiss-made to very high standards using the best quality components and movements (also from Switzerland), protected by extra strong cases with anti-reflective coated sapphire crystals. The Nite MX20 has a gunmetal black PVD case with matching polymer strap, featuring a uni-directional safety bezel - if knocked you will think you have been underwater longer, not shorter.

Water-resistant to 660ft.10 year battery. Case diameter 45mm, weight 100 grams.
