UR-1001

The UR-1001


The UR-1001 is a grand über complication both measuring and quantifying the era in its entirety, from a solitary second to astronomical millennia. Exuding force from a case seemingly carved from a block of solid metal, 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.

Insights

Swiss timepieces Special-project watch UR-1001

Day/Night indicator

The Day/Night indicator is a rotating disk in dark Super-LumiNova® for the night, satin finish for the day and a striped mix for dusk/dawn.

Revolving satellite calendar

The Revolving Satellite Calendar is an original annual calendar complication in the same family as the hour satellite complication. Months and date replace hours and retrograde minutes. 

Power reserve indicator

39h power reserve.

Hour satellite complication and retrograde minute hand

The Hour Satellite Complication of the Zeit Device is a ‘flying’ design in that there is no top bridge supporting the carrousel. The retrograde minute hand is fixed to a sprung ring around the circumference of the satellite complication.

100-year indicator (BACK)

The 100-year indicator advances in 5-year increments and acts like the odometer of a car. The 100-year and 1000-year indicators of the UR-1001 register the total running time of the movement.

1000-year indicator (BACK)

When the hand reaches the 100-year mark, the small pointer at the bottom of the 1000-year indicator on the left takes a small 100-year step upwards on its imperceptibly slow, but deliberate journey to a new millennium.

"Oil Change” indicator (BACK)

The shortest time interval measured on the back is the 5-year Oil Change indicator, which alerts the user when a service is due (after three years). The counter is reset to zero when the timepiece is serviced.

“Since we founded URWERK, we have developed new methods of displaying time. However, we were always constrained by the size of the wristwatch. With Zeit Device we could allow ourselves carte blanche and created a larger playground for our imaginations… and then filled it with all of our complications and indications.”
