UR-103.08 TiAlN

One tough mother…
The UR-103.08 TiAlN joins the URWERK Pre-Owned collection.

You might be asking what is TiAlN?
Titanium Aluminum Nitride. A treatment well-known in the industrial industry for its exceptional properties. A TiAlN coating less than 4 microns thick has the effect of multiplying the resistance of the underlying metal to scratches, shocks, oxidation and even acids. Applied to tools when machining metals to guarantee the tool head is harder than the material to be machined.

Harder than DLC and a Vickers rating of 3500. To put into context, steel is only 600 Vickers and sapphire is 4000. Apart from its immense strength, the UR-103.08 TiAlN has great beauty as well. A striking purple/brown colour is created by playing with the Titanium/Aluminium ration and resulted in something never seen before in the watch industry.

Initially released in 2007, now 12 years later you again have the chance to wear this jewel in the UR-103 crown! With our iconic satellite complication, displaying the hours on four orbiting satellites that travel along the minute track from east to west like the sun. Flip it over to reveal the control board with power reserve indicator, 15 minute and seconds dials for precise time setting, and a user adjustable fine-tuning screw, to adjust the watches rate if running fast or slow.

As with all our Pre-Owned collection, we have fully serviced the watch and refurbished it. As well as adding a new strap and comes with a URWERK box and new Pre-Owned international warranty for two years.

Creators Thoughts:

Felix Baumgartner - "Working for years at/and with Gros atelier (our genius case maker artisan) I discovered an extremely sharp machining tools with a strange colour! After research I found out where they are made and for what. The machining without the need for oil, so to give strength to the tool and to protect it. This is from where this treatment comes, so no design, a pure technical treatment (All PVD used in watches have primarily a design goal and are not applied in the tooling industry)

Martin Frei - “Next to the slightly sharper 70’s cut of the U-shaped Targa crystal, the UR-103 TiAlN finally, and for the first time, got an exotic protection coating for its futuristic case. I have always dreamed of darker or even black coloured watches. The shape of any object looks so different and beautiful in a dark colour and it always vexed me that it was not possible to work with the full palette of colours and gradations. Then we discovered the extraordinarily striking, dark violet copper coating used to protect our drilling tools, and we instantaneously decided to create a watch using the Titanium based TiAlN coating to transform our UR-103 case into a stunning, out of the ordinary looking contemporary time piece."

Condition Rating UR-2: Good condition, minor marks, wear and tear, movement in serviced and working condition.
