URWERK UR-100 Electrum Limited Edition

URWERK presents UR-100 Electrum, a limited edition watch from the independent Swiss watch brand’s UR-100 collection. This 25-piece edition has a case made of an organic gold and palladium alloy. In addition to its sunny yellow colour, it features a structured, pleated and undulating surface.

Electrum is one of the original precious materials, regarded by the ancients as a veritable treasure. This gold and silver alloy was indeed much coveted among Ancient Greeks, Amerindian civilisations and Ancient Egyptians.

In addition to the satellite-type hours and minutes display, the UR-100 Electrum provides a new item of information. Once the 60th minute has passed, the minutes hand vanishes and reappears as a kilometre counter illustrating the 555 kilometres travelled every 20 minutes by every inhabitant of the Earth. This in fact corresponds to the Earth’s average speed of rotation calculated at the Equator.

Earth’s revolution around the sun – corresponding to 35,740 kilometres per 20 minutes – is displayed exactly opposite. On the face of the UR-100 Electrum, hours and kilometres thus share the same status, the same scale of value. These units are illuminated in incandescent green for the hours and in blazing white for the kilometres.

The UR-100 Electrum watch is equipped with URWERK automatic calibre 12.01 with its three-satellite time display. The satellite indicating the exact time moves from 0 to 60 along the minutes track.
