Urwerk UR-112 Aggregat “Back to Black”

If I were a hero? I'd be a James Bond-like badass.

If I were a colour? I would be the darkest night.

If I were a quality? Punctuality of course, it's the only rule I abide by.

If I were a car? I would be the supremely desirable Bugatti Atlantic Type 57 SC.

I am the UR-112 Aggregat Back to Black.

I am the most digital of all URWERK mechanical timepieces.

I am a jumping hour, dragging minute and digital second watch.

I am all that and so much more...

"I’m a superb mechanism in a steel and titanium body."

The UR-112 Aggregat Back to black comes in a steel and titanium body with a complex architecture. Let's start with its upper part. Its steel bonnet is grooved and openworked. It gives a glimpse of the richness of this gleaming speed machine.

This cover opens vertically to give access to the secondary power-reserve and digital seconds indications. Its central titanium body is satin-brushed, sandblasted and beadblasted, thereby forming a field of functional microdots. The two blackened steel wings of the UR-112 Aggregat Back to black fit into this central body. Each zone, each space, each element has its own texture, its own finish, its own language.

"I was born amid the smell of petrol and polish."

The UR-112 Aggregat Back to Black belongs to the Special Project line. This is a departure from the founding concept of URWERK's wandering-hour indication, on a whole new scale, with new volumes for the UR-122 Aggregat and its UR-13.01 caliber. 

Martin Frei, co-founder of URWERK said: "The inspiration for the 112 line came straight from the USA. Felix and I were lucky enough to discover the impressive car collection of Mr Ralph Lauren. Amongst the rarest models was the Bugatti Atlantic. WOW! It was love at first sight. Its perfect lines, its spine running along its body, its Art Déco features. This Bugatti is a true wonder! It was the muse that inspired my first drawings of the UR-112.”

"I am a watchmaking fantasy driven to the extreme."

The central body of the case contains the driving and regulating components of the UR-13.01 caliber. A large barrel providing 48 hours of power reserve is coupled with an automatic-winding rotor. Pressing the two pushers on the sides of the watch opens the cover and reveals the power-reserve indicator and the spectacular small seconds. The latter is composed of a skeletonized silicon disk attached to a red anodized aluminum bridge, a typical URWERK design feature.

A transmission shaft stands out in the middle of this incredible mechanism. Measuring several centimeters in length, it's possibly the longest component in contemporary watchmaking. To guarantee its lightness and rigidity, it's made of titanium and ensures the coupling with the display module, located at the front of the shell. It establishes this link thanks to a new succession of gears that drive the hours and minutes prisms via two 90° bevel gears. 

The black aluminum prisms featuring grooved sides are enhanced with Super-LumiNova and secured by planetary systems that ensure they rotate both on their axis and in space. This kinematic approach calls for absolute precision and contributes to endowing the UR-112 Aggregat Back to black with a totally unique and unconventional design. So URWERK!
