The 103.08
For the very first time, URWERK presents its iconic 103 encased in steel. With this new model, URWERK blurs the frontier between horological art and cutting-edge technology as the coat of the steel 103.08 is the hardest known in the world of haute horlogerie.
  
The secret element of this steel case is TiAlN - Titanium Aluminum Nitride - a treatment well-known in industry for its exceptional properties. The TiAlN coat -less than 4 microns thick - has the effect of multiplying the resistance of the underlying metal to scratches, shocks, oxidation and even acids.
"TiAlN is a hard material which can be used as protective coating to enhance the lifetime o a variety o work pieces against mechanical or chemical attacks. The hardness oTiAlN is oen beween 30 and40 GOaIn comparison, the hardness of DLC (diamond like carbon) is 20-25 GPa”. Dr Ayat Karimi, Institute of Complex Matter Physics, EPFL, Lausanne.
The new 103.08 in TiAlN treated steel is the new jewel in the crown of URWERK's 103 collection. The 103.08 is lighter than its gold and platinum stable mates, yet is much harder. The proof is in the numbers:
Gold : 380Vickers
Steel : 600 Vickers
TiAlN coat : 3500 Vickers
Sapphire: 4000 Vickers
TAilN is an application which was originally developed for industry. When machining metals, the first requirement is that tool is harder than the material to be machined; therefore considerable research goes into developing new methods of hardening.
Attractive aesthetics can be added to TiAlN's technical superiority. Its colour is dependant on the Titanium/Aluminium ratio and can range from melting bronze to stormy black.
