URWERK UR-112 Aggregat Limited Edition

The UR-112 Aggregat is the latest addition to URWERK’s Special Project collection.

Driven by a complex mechanical movement, Aggregat offers fully digital time displays, from hours down to seconds. The hour and the minutes are displayed on triangular prisms operating under transparent cylinders, which appear as levitating mechanisms to be admired through the crystal.

On the left, the digital hour display. Each of the 12 numerals is engraved then filled with Super-LumiNova. The transcription of time takes the form of a sign display switching sharply to a chronometric rhythm. On the right, the same system displays the minutes. Minutes free from the strain of the singular and instead jump in 5-minute increments.

The operation of the jumping hours display is driven by the advance of the minutes. At the 60th minute, the force accumulated during those last 3600 seconds is released to change the time to the next hour.

The primary source of all this power is rooted in the basic movement opposite this Dantesque construction. A long, thin rod connects the body and head of the UR-112. This is the cardan shaft, a central part of vital importance to this mechanism. A complex set of cogs, a succession of gears, allows this axis to transmit all the energy required. This transmission shaft with double gearing – one at each end – is perpendicular to the horizonal time indication.

The movement of the UR-112 nestles inside a hunter case with a hinged titanium protective cover. Pressing the pushers on either side of the case unlocks the cover and it springs up, revealing an elaborate display of digital seconds. Etched on tiny silicon wafer disks, tiny numerals parade under a magnifying lens beside the only analogue display of the UR-112, a 48-hour power-reserve indicator.

This first edition UR-112 Aggregat is limited to 25 pieces with a matte finish. It has sober colors, an anthracite body with black sides complemented by a cover in the same color.
