First launched in 2012, the UR-210 features the what’s come to be regarded a classic display of contemporary independent watchmaking. Three four-sided minute hands act as cowls that transport the displays of the hours as they traverse a linear minute track. The architecture of the system remains open to view through the large sapphire crystal cover. But the signature feature of the UR-210, the one that sets it apart from other Urwerks, is its winding-efficiency indicator, whose output is a calculation of energy flow in the watch. Is it putting out more than it’s taking in? Or, more to the point, are you moving around enough to keep your watch wound? Taking this data, the wearer can then adjust the sensitivity of the UR-210’s winding mechanism via a nob on the back of the watch. A sedentary lifestyle would call for a very sensitive rotor and winding system; an extremely active one would call for something less sensitive. And if you want to stop automatic winding altogether, that’s another option this UR-210 allows. You can essentially turn it into a manually wound watch.
