Urwerk now endows the 21st century with its own epoch-defining time – or Zeit in German – measuring instrument: The UR-1001 Zeit Device.

In our fast-paced lives, we often describe time as fleeting. Our timepieces reflect this perception by measuring relatively short intervals, i.e., seconds, minutes, and hours. A few watches take a longer view and track days, months, and years, and some even leap years. But rarely do timepieces do justice to a universe measured in billions of years – as a true Zeit Device should.

The UR-1001 is a true Zeit Device: It is a grand über complication that measures and quantifies the era in its entirety, from a solitary second to an astronomical millennium. Exuding force from a case seemingly carved from a solid metal block, the UR-1001 marks the passage of time in seconds, minutes, hours, day/night, date, month, years, 100 years, and all of the way to a monumental 1,000 years!

The Zeit Device houses a constellation of indications, including orbiting satellites and a comet-like flying retrograde. Dials, springs, satellites, carrousels, retrograde spiral spring were all manufactured in-house by Urwerk, as were most of the components in the Zeit Device's complications and indications.
