First and foremost, the UR-100 is slim – extra-flat for a satellite-geared watch – with angular contours; it’s an elongated octagon with three notched sides. The form uses subtle asymmetry, taking clues from Han Solo’s Millennium Falcon. This UR-100 is cut from a solid block of 2N yellow gold, its surface satin-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 astrophysics govern the Urwerk universe with rotating satellites displaying 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. 

And last, but certainly not least, are the discreet spacetime indications on each side of the top of the dome’s periphery, which are both essential for intergalactic voyages and unique on planet earth. After each of the three red minute arrowheads passes 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 around the sun over 20 minutes. Spacetime never looked so good!
