The self-wind­ing UR-111C is Urwerk’s lat­est ex­er­cise in com­plex mi­crome­chan­ics, none of the in­di­ca­tions of the UR-111C are con­ven­tional, the min­utes are shown lin­early for aes­thet­i­cal rea­sons and dig­i­tally for pre­ci­sion. Never has a roller on the case per­formed the func­tions of the crown, nor have the run­ning sec­onds me­an­dered across a clus­ter of op­ti­cal fi­bres. Nor would it be an authen­tic Urwerk watch if its case didn’t look as if it had been de­signed by a Sci-fi pas­sion­ate. And in­stead of a con­ven­tional crown at the end of the stem, a roller is in­te­grated into the top of the case above and par­al­lel to the wind­ing stem. Rolling the long fluted cylin­der to wind the watch is in­deed a new sen­sa­tion, but mak­ing it pos­si­ble re­quires minia­ture gear­ing, com­plex ar­tic­u­la­tions and in­ter­me­di­ate wheels to con­nect the con­trols to the wind­ing stem. The same ap­plies to the orig­i­nal way of set­ting the time. In­stead of pulling out a crown, swing out a lever from the side of the case and turn the roller in ei­ther di­rec­tion. The hours and two ver­sions of the min­utes are dis­played within glass sap­phire cov­ers along the side of the case, so they are vis­i­ble at a glance with­out turn­ing the wrist or let­ting go of the steer­ing wheel. Again, con­vert­ing the hor­i­zon­tal move­ment to a ver­ti­cal time dis­play re­quired pre­cisely an­gled trans­mis­sion with minia­ture bevel gears. The jump­ing dig­i­tal hours and pro­gres­sive min­utes are dis­played on ro­tat­ing trun­cated cones left and right of the ret­ro­grade lin­ear in­di­ca­tion of the min­utes.
