URWERK UR-100 Gold Edition

The new Gold Edition is the fourth episode in the URWERK UR-100, an exclusive collection of atypical time instruments inspired by the intergalactic voyages. Developed and produced by the horological studio URWERK in Geneva, the UR-100 watch pushes the boundaries of technology, design, indications, and functionality.

The UR-100 features an elongated octagonal case with three notched sides. This UR 100 is cut from a solid block of 2N yellow gold, its surfaces a tin-finished to the same pale shine as the Star Wars droid. Topping the case is a sapphire crystal bubble reminiscent of the shape of the first URWERK models, the dome housing the control center of this intergalactic visitor.

The UR-100’s rotating satellites display the hours and minutes. Isochronal revolutions create a miniature cosmic ballet, the hour satellites also displaying minutes as they traverse 120 degrees across the bright green scale. A bold red arrowhead marks the confluence of hours and minutes, offering a unique, highly legible, and intuitive time display.

Even while maneuvering at light speed, the automatic winding system is never overloaded thanks to the Windfänger’s regulation of the oscillating mass: this planetary gear limits the speed of rotation of the rotor, minimizing both excessive winding and wear and maximizing reliability and lifespan.

The discreet space time indications on each side of the top of the dome’s periphery are both essential for intergalactic voyages and unique on planet earth. After each of the three red minute arrow heads pass the numeral 60 they disappear and then reappear again on two separate kilometer scales.

The first display at 9 o’clock marks the 555 km traveled along the equator during 20 minutes of the earth’s rotation, the second display at 3 o’clock indicates the distance – 35,740 kilometers – traveled by the earth as it orbits the around the sun over 20 minutes.

To participate in the fight against Covid-19, URWERK will auction “Fight C-19”, the first UR-100 in gold, on the URWERK website, and distribute all money raised to organizations fighting against the COVID-19 pandemic.

The auction will begin at 4 pm GVA time on Friday the 8th of May, 2020, and run over two days. URWERK will select which organizations fighting against Covid-19 in partnership with the successful bidder of the No. 1 gold UR-100 “Fight C-19”.
