The Tudor Ranger is back to celebrate the 70th anniversary of the British North Greenland Expedition. The watch returns with a revamped design that now features a 39mm case in satin-brushed 316L stainless steel. The grained domed dial features Super-LumiNova-painted markers and "Ranger" hands with the same material. The watch will be available on a 316L stainless steel bracelet, a striped Jacquard fabric strap, or a hybrid rubber and leather strap. Powering the watch is Tudor's own MT5402, a COSC-certified automatic movement with a a silicon balance spring and a 70-hour power reserve.
