News: Presenting the URWERK UR-210Y 'Black Hawk'. A Limited Edition of Only 75 Pieces.

URWERK continues to wow the watch industry with their stunning complications and forward thinking design. After unveiling the fascinating EMC timepiece at the end of August of 2013, this time, URWERK has taken another big step unveiling the UR-210Y Black Hawk. A watch available in a limited edition of only 75 pieces in Titanium and AlTiN-treated steel.

This new timepiece, just like all other URWERK watches is not your run-of-the-mill watch. The UR-210Y tells time through a satellite complication display located at the center of the dial and fitted with wandering hour and retrograde minute indicators. Yhe UR-210Y’s satellite complication with retrograde minute is both highly original and totally explosive. The principal feature is a high-tech, oversized, three-dimensional retrograde minute hand. Its function is to enclose the hour satellite and indicate the time as it transverses the 0-to-60-minute scale. This one-hour journey through time, tracing an arc of 120°, is smooth and fluid. But the true nature of the piece is revealed at the end of the 59th minute. Then a sharp distinct “click” signals the return of the minute hand to its starting point. In less than 0.1 of a second the hand flies back to dock with the next hour satellite. This high-speed retrograde system is based on three key elements. A central axis set in ruby bearings provides excellent stability for the satellite/retrograde complication. A cylindrical marine chronometer type spring runs vertically around the axis and generates the optimal tension required for the retrograde minutes flyback. A minute hand, which also forms a frame for the hour satellites, displays the time in an extraordinary way. Milled from aluminum to exacting tolerances of approximately 3 microns, the whole structure has a total weight of just 0.302 grams and is counter balanced by a brass weight. This three-dimensional cage offers rigidity as it transfers energy from the
cylindrical flyback spring in the top center of the carrousel to the double-star gear underneath. Lastly, a double coaxial star-shaped cam regulates the retrograde mechanism through its gearing and its rotation defines the trajectory of the minute hand. When the minute hand reaches 60, the double star trips a (one of three) hockey-stick shaped spring under the mechanism, which liberates the minute to fly back to the next hour satellite at 0-minutes.

Equipped with a winding efficiency indicator —a world's first— on the left top corner of the dial —11 o'clock position—, the display lets you see if you are active enough to replenish the watch movement with enough energy via its automatic winding rotor, or if the watch is just running on stored energy. The watch also lets you change the winding efficiency of its rotor so that it matches your daily rhythm, and I can even let you switch to manual winding mode if that suits the wearer better. This indicator will measure the winding efficiency over the last two hours. If the wearer's activity has been good enough to replenish the UR-210Y’s energy levels, the efficiency indicator will point emphatically to the green zone. If the wearer has not generated enough energy, the winding efficiency indicator will point to the red zone.

Once the UR-210Y indicates an insufficient supply of energy, the wearer can then position the winding efficiency selector at the back of the watch to “Full” and then the rotor will then convert the slightest movement into stored energy. In this configuration, a turbine connected to the rotor provides smooth, unimpeded power. But if the wearer is more active, then that may provide more power than required and unnecessarily wear the mechanism. In that case, the wearer would position the winding efficiency selector to “Reduced” to engage the rotor damping system. An air turbine compressor mounted on ruby bearings spins and creates internal resistance —enough friction to slow down or dampen the automatic winding rotor. In the “Stop” mode, the automatic winding system is disabled completely and the UR-210Y runs off reserve power and may require manual winding.

Because of its black color, the watch has earned the nickname “Black Hawk”. The massive case measuring 43.8 mm wide, 53.6 mm long and 17.8 mm thick, is made of high-tech titanium and AlTiN-treated steel, which increases its resistance to scratches and acids. The watch is also fitted with an oversized winding crown that takes the center stage as it is the norm on most of the URWERK creations. Additionally, for the first time in the history of an URWERK timepiece, the watch is fitted with a black nylon fabric strap.

The caseback offers a limited view of the URWERK Caliber UR-7.10 fitted with 51 jewels, mono-metallic balance, spring flat balance, turbine equipped self-winding mechanism and which provides a power reserve of 39 hours when fully wound. On the back we also see the winding efficiency selector, as well as a small plate where the limited edition case number is engraved. The watch is waterproof to a depth of 30 meters.
