Urwerk - UR-105 Tantalum Hull

Urwerk presented the new UR-105 TTH, the model that marks the end of the 105 Collection. The price of the Urwerk UR-105 Tantalum Hull is CHF77000

Urwerk presented the new UR-105 Tantalum Hull (TTH), the model that marks the end of the 105 Collection. In fact, with a production of just 150 pieces per year, the Swiss brand has to replace a collection in order to bring new creations in their catalogue.

The new watch comes in a “soap bar” case in titanium and tantalum that is 39.5 mm wide, 53 mm long and 17.8 mm high.

Characterised by a fascinating blue-gray luster, Tantalum is a precious metal that is very difficult to machine and finish. Rarer than gold, harder than steel, and highly corrosion-resistant, tantalum is an alternative to platinum  for its inertness. Thanks to its high density, it is extremely resistant to acids. 

A limited edition of just 12 pieces, the UR-105 TTH reveal its mechanics by sliding the catch on the top of the case: an openworked carousel carries four satellites, each bearing three numerals for the hours that rotate in turn along the minute track, providing both analog and digital time displays.

A power-reserve indicator and digital seconds make up the rest of the information displayed on the dial. The digital seconds are remarkable in that they indicate tens of seconds.

On the back, two pneumatic turbines regulate the movement’s automatic winding system, which can be easily adjusted using a small lever depending on how active the wearer is. 

In the "FULL" position, the slightest movement of the wrist is enough to wind the mainspring. In “STOP” mode, the automatic winding system is deactivated and the UR-105 can be wound by using the crown. A third intermediate position, “RED” (for REDUCED), engages the turbines to dampen the winding rotor and avoid overstressing the mainspring, if you are particularly active. Beating at a frequency of 4 Hz (28,800 vph), the UR 5.03 calibre guarantees a power reserve of 48 hours.

Matched to a Vulcarbon rubber strap with black DLC buckle, the Urwerk UR-105 Tantalum Hull (TTH) has a price of CHF 77,000 before local sales taxes. urwerk.com
