Urwerk - UR-210 Black Platinum

Comunicato Stampa disponibile solo in lingua originale. 

Geneva – January 2018

Once they’ve seen it in action, nobody can deny the appeal of the UR-210. To appreciate it fully you have to keep your eyes glued to the dial as the minutes hand approaches the end of its hour. Don’t blink, because if you do, you’ll miss a display of controlled energy in the lighting return of the retrograde hand as it snaps back to the start of the next hour.

Today #urwerk presents the extraordinary UR-210 in a black platinum version, in keeping with a tradition held since its foundation. The Black Platinum model is the most select and exclusive of the UR210s, and as such, irresistible. 

It’s a few seconds to the hour and time holds its breath as it prepares to return the minutes to their starting point. The action is too swift for the eye but you hear the sharp click that announces the arrival of the hand exactly on zero. 

The spectacular combination of the revolving satellite complication and retrograde minutes is seen nowhere as in the UR-210. The prominent three-dimensional minutes hand acts as a high-tech cowling that encloses the hours and carries them in turn smoothly across the scale of minutes. The lightning speed of the flyback— less than a tenth of a second — depends on three key factors: 

-The central hub ensures that the mechanism remains stable. Turning on ruby bearings, it constitutes the rock on which the entire complication rests. A cylindrical spring of the type used in marine chronometers along the shaft accumulates the power for the retrograde action. 

-The unusual minutes hand that acts as a cowling to transport the hours has equally uncommon dimensions, machined to the hundredth of a millimetre. The 22.29mm long metal structure, with a width of 8.03mm and a height of 7.3mm, weighs only 0.302 grams. Machined in aluminium, it is perfectly balanced by a brass counterweight. 

-A double coaxial cam in the shape of a star governs the retrograde action. Its gearing and then its rotation determine the trajectory of the minutes hand.
