INTRODUCING: Urwerk UR-112 Aggregat “Back to Black”

The Urwerk UR-112 Aggregat "Back to Black".

Urwerk’s latest timepiece is a lethal-looking mechanical wrist machine.

Two years ago, Urwerk launched the UR-112 Aggregat as part of its Special Projects collection. The UR-112 is inspired by Ralph Lauren’s Bugatti Atlantic and recalls the design of Bulova’s Computron, which displays the time at the end of the watch case for convenient reading of time when you’re driving. The top of the watch case, which looks like the grille of a car, lifts to reveal the additional indicators, while the time is shown at the wider end of the watch case.

The latest release of the watch presents the UR-112 Aggregat in an all-black DLC-treated titanium-and-steel case in a matte finishing that gives the watch a Batmobile-style appeal.

The steel bonnet of the case is open-worked and lifts up to reveal the power reserve and digital seconds indicator. It locks into the main titanium body, which is satin-brushed, sandblasted, and bead-blasted.

The time display is distinct from Urwerk’s past designs. There are no satellite or sector-style displays; instead, prisms with digital indicators show the jumping hours and minutes in 5-minute increments. A secondary trailing indicator for the minutes reveals the exact time.

The minutes and hours are on prism displays that rotate to indicate the time.

Felix Baumgartner, co-founder of Urwerk, explains, “This UR-112 is pure madness in terms of the mechanics and the finishes. The energy generated by the UR-112’s central engine is being distributed in four directions along no less than 12 axes. It’s actual mechanical lace. We will only be able to make a very limited number of them, but this is sheer, unadulterated watchmaking pleasure!”

The UR13.01 calibre that powers the display has a large barrel providing 48 hours of power and is self-winding. Two pushers on the sides of the case lift the steel bonnet to reveal the power reserve. The small seconds display uses a skeletonised silicon disc, joined to a red anodised aluminium bridge. Running across the centre of the movement is a central titanium transmission shaft that joins the movement with the time display at the front of the watch via perpendicular bevel gears and a series of wheels. 

The watch is sized at 52mm by 42mm and priced at CHF 280,000. In Southeast Asia, it’s available via The Hour Glass.
