ZrN stands for Zirconium Nitride, which Urwerk has utilized to enhance the scratch resistance of this new time keeper.  In their own words -

A champagne-coloured high-performance ceramic machine tool coating which, while only a few microns thick, is very hard (2000 Vickers); provides excellent scratch, wear, and corrosion resistance; and exhibits good lubricity and ductility. The ZrN coating is vapour-deposited over the sandblasted steel bezel to provide the timepiece’s distinctive frosted pale gold effect. ZrN coated tools are suited to non-ferrous metal applications, e.g. aluminum, copper and titanium, and are used for coating medical devices and aerospace components.

The UR-110 ZrN Torpedo is an Édition Spéciale of just 12 pieces, making it a very Rare Species, and is available exclusively from Chronopassion (Paris), Marcus (London), The Hour Glass (Singapore) and Westime (Los Angeles). Each individual timepiece will be identified by a red satellite hour numeral.

From the base of its unusual asymmetrical case to the three arrow-shaped “torpedoes” flying in formation with the mission of indicating the time, the UR-110 has serious attitude.

Enveloped in a secure titanium case, planetary gearing keeps the three hour satellites in parallel formation while they take turns to indicate the time as they pass the 60-minute track. An “Oil Change” indicator alerts the user when it is time for a service; a “Day/Night” indicator helps keep track of changing time zones; and twin turbines on the back minimize wear in the automatic winding system.

This new complication is made possible thanks to a construction with three levels of complexity:

-  A central carousel providing the complication with stability and equilibrium.

-  Planetary gearing assuring 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 counter balance – 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.
