Wealth Bulletin

The Hardest Watch in the World?

Avant garde Geneva-based watchmaker Urwerk produces what they claim is the world's hardest timepiece, the 103.08 TiAlN, the Wealth Bulletin reports. That stands for Titanium Aluminum Nitride, a coating less than 4 microns thick and much lighter than gold and platinum but much, much harder - more than 5 ½ times harder than steel, in fact. Nearly indestructible, the watch is practically immune to scratches, shocks, oxidation and even acids, they claim. Theirs is the first timepiece ever to use the coating.

Shown here in rose gold, the limited edition watch will run you about $70,000. The slanting sides of Urwerk's signature "orbiting hour satellites" allow you to see what time it is without turning your wrist. The company, which launched in 1997, has been doing revolutionary things to timepieces, yet their inspiration goes back several centuries. The name is an homage to Ur, an ancient city in southern Mesopotamia, one of the earliest known civilizations in the history of the world. Take a look at some of their other designs below.
