The Ranger model was launched to mark the 70th anniversary of the British North Greenland Expedition. It is a tool watch celebrating the spirit of this daring adventure, complete with Manufacture Calibre MT5402, a 39-millimetre case and a clasp with rapid adjustment system. The Ranger model respects the aesthetic standards established in the course of its history, especially its dial with Arabic numerals at 3, 6, 9 and 12 o’clock, whilst incorporating new state-of-the-art technical elements. It continues, within the TUDOR collection, the tradition of the expedition watch.
