Description

Urwerk UR-210Y "Black Hawk" wristwatch, featuring the self-winding Calibre UR-7.10 movement with a 39-hour power reserve; black dial with hours, minutes & markers painted in Super-LumiNova; satellite complication showing wandering hours with three-dimensional minutes hand; power reserve indicator at 1 o'clock; winding efficiency indicator at 11 o'clock; winding regulator on case back visible through a sapphire-crystal window; and 53.6mm x 43.8mm, titanium & AlTiN-treated steel case on a Baltimora black technical fabric strap secured by the Urwerk buckle.

Urwerk UR-210Y The Black Hawk features a satellite complication display with wandering hour and retrograde minute indicators. The watch is equipped with a winding efficiency indicator, which is the world’s first complication of its kind. This practical addition to the watch movement enables the wearer to see if the watch is running on stored energy, or if the wearer’s movement produces enough kinetic energy to wind the spring. In addition, to the winding efficiency indicator, located at 11 o’clock position, there is also a traditional power reserve indicator, placed at 1 o’clock.

The winding efficiency indicator is pointing into either green or red zone, depending on whether the watch is using more or less energy than what the wearer is generating. If the watch indicates an insufficient supply of energy, the wearer can react by placing the winding efficiency selector on the back of the watch to “FULL” to signal the rotor to transform even the slightest movement into stored energy. On the other hand, if the wearer is more active, the winding efficiency selector should be positioned to “REDUCED,” which triggers the rotor damping system. There is also the “STOP” mode in which the winding system is disabled, and the watch runs on power reserve.
