Ultra rare, ultra-cool, the UR-110 AlTiN Singapore limited edition of five pieces was created initially for our retail partner, The Hour Glass, in 2012.

We now have one of the rarest UR-110s available in our Pre-Owned collection. The watch features blue numerals on the satellites and minute indexes, making it instantly recognizable as the Singapore edition. A case in titanium with a steel bezel finished with our AlTiN coating.

Aluminum Titanium Nitride (AlTiN) is a hard coating AlTiN is generally applied to steels, hardened steels, and stainless steel materials where high wear resistance and lubricity are needed. AlTiN coating provides exceptional oxidation resistance and extreme hardness. It also gives the watch a stealthy matte black finish.

The UR-110 continued our radical tradition of telling the time using orbiting satellite complications. In the UR-110, the time is always shown on the watch's right side. A revolving hour satellite follows a vertically arced line, graded from 0 to 60 minutes, in a downward motion. Planetary gearing keeps the three hour-satellites and their arrow-shaped "torpedoes" in parallel formation as they take turns to indicate the time they pass the 60-minute track. This performance is made possible by utilizing an architecture featuring three levels of complexity:

- A central carousel provides the complication with stability and equilibrium
- Planetary gearing assures the parallel rotation of the three hour-satellites as they orbit the dial
- Three counter-rotating hour modules – each comprising an hour satellite, minute hand and counterbalance – are each mounted on a planetary gear. These three modules are in constant counter-rotation to offset the direction of rotation of the central carousel.

The dial side control board displays Day/Night indicator, 'Oil Change' alerting service intervals and small seconds. Turn the UR-110 over and reveal the twin-turbine windows. These turbines help regulate the uni-directional rotor's winding rate, preventing extra wear and tear.

The 110 is now discontinued, making this the perfect opportunity to add one to your collection. In like-new condition, with a URWERK Pre-Owned two-year warranty, fully serviced by our own watchmakers. Completed with a new Baltimora textile/leather strap and original URWERK box.


Felix Baumgartner - "A watch to celebrate our partnership with The Hour Glass. Experts in high-end Swiss horology in Singapore, The Hour Glass is an internationally renowned watch retail group. Located in 12 different cities in the Asia Pacific."

Martin Frei - "The UR-110 won a GPHG Design award, and I have to say I was astonished and happy about this because the watch has a very unusual, odd geometry. It is asymmetrical in every possible way (of course, that's the way I like it:)!"

Condition Rating UR-1: As new, no or very few signs of wear, the movement is serviced and in working condition.
