To mark the 70th anniversary of the British North Greenland Expedition, TUDOR is presenting the Ranger model, 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.
It was on 8th July 1952, that the British North Greenland Expedition left Deptford, an area on the banks of the Thames in London, for a two-year scientific mission studying ice sheets in Greenland. Equipped with the brand-new Oyster Prince model, TUDOR’s first watch that was both automatic and waterproof, the members of the expedition, mainly British scientists and sailors, conducted in-depth glaciological and seismic surveys at several sites. TUDOR also asked them to gather performance data for the 30 Oyster Prince watches that would be worn under extreme conditions. It is the adventurous spirit of these pioneers of arctic exploration that the latest addition to the Ranger line celebrates, offering an affordable combination of state-of-the-art watchmaking technology and historic aesthetics.
THE RANGER SAGA
The history of the Ranger name dates back much further than the British North Greenland Expedition. Although the TUDOR watches used by its members from 1952 to 1954 never bore this inscription on their dials, subsequent Ranger models have perpetuated the concept of the expedition watch born at TUDOR during this time. That of a robust, practical, and affordable instrument.
The origins of the TUDOR Ranger family date back to 1929. This was the year when Hans Wilsdorf registered the “Ranger” name, just three years after registering the “The TUDOR” trademark. At the time, the name was not used to indicate the model specifically, but instead to add an adventurous aspect to certain watches in the TUDOR collection. The aesthetics that we now recognise as the Ranger didn’t appear until the 1960s, with its large Arabic numerals, generously coated with luminescent material at 3 (for models without the date), 6, 9, and 12 o’clock, as well as its uniquely designed hands.
THE SPIRIT OF A TOOL WATCH
The new Ranger model indeed 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, in particular a high-performance Manufacture Calibre and a TUDOR “T-fit” clasp with rapid adjustment system. It continues, within the TUDOR collection, the tradition of the expedition watch, born with the Oyster Prince watches used by the members of the British North Greenland Expedition. The tradition of a robust, practical, and affordable instrument.
To echo this functional heritage, the 39-millimetre case and the bracelet of the Ranger are satin-brushed, creating an overall matt finish, in the purest spirit of a “tool watch”. Some elements, however, are polished to strengthen the lines of the case, including the inner edge of the bezel. As for the dial, an attentive eye will notice a detail of historic influence, hour markers painted in luminescent material. Beige in colour, they perfectly contrast with the grained, matt black dial and match the tone of the TUDOR shield logo and inscriptions. The arrow-shaped hands, rounded for the hours hand and angular for the seconds hand, are characteristic of Ranger aesthetics, with a novel touch, the tip of the seconds hand in burgundy.
The Ranger is offered with an entirely satin-brushed steel bracelet, with the TUDOR “T-fit” clasp equipped with a system for rapid length adjustment. Easy to use, requiring no tools and offering five positions, this practical system allows wearers of the TUDOR Ranger to carry out a fine, instant adjustment of the total length of the bracelet along an adjustment window of 8 mm.
MANUFACTURE CALIBRE MT5402
The Ranger model is equipped with Manufacture Calibre MT5402. Its construction has been designed to ensure robustness, longevity, reliability and precision due to its variable-inertia balance, which is held in place by a sturdy traversing bridge with two points of fixation. Thanks to this balance and the non-magnetic silicon balance spring, the Manufacture Calibre MT5402 has been certified as a chronometer by the Official Swiss Chronometer Testing Institute (COSC), with its performance going beyond the standards set by this independent institute. In fact, where COSC allows an average variation in the daily running of a watch of between -4 and +6 seconds in relation to absolute time in a single movement, TUDOR insists on between -2 and +4 seconds’ variation in its running when it is completely assembled.
Another notable feature is that the power reserve of the Manufacture Calibre MT5402 is “weekend-proof”; that is to say about 70 hours, which enables the wearer to take the watch off on a Friday evening and put it back on again on Monday morning without having to wind it.
