EMC Time Hunter Desert Sage

Style serving function
The EMC Time Hunter Desert Sage belongs to the UR-Chronometry family, which encompasses URWERK watchmaking concepts dedicated to outstanding precision. They indeed offer the unique possibility of measuring and adjusting the rate of their movement. An EMC Time Hunter is essentially a dual measuring instrument. Like a compass, a sextant, a machine tool, its appearance and even its surface all signal its nature. The EMC Desert Sage is crafted from steel and its caseback from titanium. Its aesthetic is not round, square or cushion-like, nor indeed any of URWERK’s signature indefinable shapes. This hyper-technical “machine” hugs the contours of the ‘motor’ inside and submits to the constraints of its various organs. It is not symmetrical, regular, flat or curved, yet remains aesthetically pleasing and distinctive. EMC’s design obeys its function, transcending existing rules to create a unique personality. Moreover, its stainless steel ‘hood’ is micro-beadblasted and then given a hard, matt ceramic lacquer-type treatment. As a result, the surface of the EMC Time Hunter Desert Sage has a grainy finish reminiscent of military equipment.

Legibility
The same functionalism reigns supreme on the dial with its matt black surfaces. Each indication zone has its own clearly marked space. Each unit is painted with fluorescent green Super-LumiNova®, a neon-type colour frequently used by URWERK due to its perfect contrasts. In addition to the main dial with its chequered hand grenade pattern, which displays the hours and minutes, the EMC Time Hunter features a small disc-type seconds hand at 1 o’clock, graduated in five-second increments and located at 1 o’clock. It is complemented by a power-reserve indicator at 7 o’clock, which provides information on the state-of-wind of the hand-wound movement offering a maximum 80 hours of autonomy.

The indications linked to the chronometric (precision timekeeping) monitoring function are concentrated at 11 o’clock and indicated by the “EM Control” marking on the screw-down bezel. The rate accuracy is graduated from -15 to +15, using seconds as the measurement unit for the daily rate deviation. The amplitude ranges from 180 to 330, measured in degrees.

Heart and brain
At the very heart of the EMC concept lies a hybrid electronic/mechanical system that makes each of these timepieces totally one-of-a-kind, bestriding two worlds. It is an entirely mechanical watch, optimised with the help of an electro-optical circuit. On the one hand, its hand-wound movement stems from the mind and hands of URWERK. Designed exclusively for the EMC collections, the UR-EMC2 calibre is entirely crafted, finished, assembled and adjusted by URWERK. On the other hand, it incorporates an electronic module whose function is to measure the rate of the mechanical part. It has its own power source, separate from the rest of the movement. Positioned on the side of the case, a large retractable lever raises a dynamo which feeds the control micro-circuit. Thanks to its laser diode, it is able to collect two essential data relating to the movement. Pointing towards the balance, it reads its amplitude (an indicator of the movement’s state of health) and the rate deviation (which is an indicator of accuracy), while comparing them to an internal clock. The latter takes the form of a processor operating at a frequency of 16 MHz and serves as a reference oscillator, i.e. a benchmark. On one side, the ‘engine’; and on the other, the control unit. Yet these two entities are not sealed off from each other, quite the contrary. They are integrated, nested and URWERK has created a means of access to both that makes EMC Time Hunter the world’s only truly wearer-adjustable watch. A timing adjustment screw makes it possible to manually fine-tune the oscillation speed of the balance and thus to correct the variations in rate that inevitably appear over time and are intimately dependent on the use made of the watch by its wearer. This corrector is located on the back of the watch and is duly indicated by the engraving “Fine Tuning”. It manages the behaviour of the movement at its very heart, by modifying the length of the regulating balance-spring.
