HISTORICAL PIECES
UR-105
“The UR-105 is our URWERK Knight; the bezel evokes the breastplate of a knight’s armor, protecting the mechanism from the ravages of time."
MARTIN FREI
The UR-105 revisits URWERK's iconic satellite indication, which has been an emblematic and instantly recognizable signature element of the brand for 18 years. It is a wandering hour indication based on a carousel which carries the four satellites, each bearing three numerals for the hours.
The hours successively sweep past the minutes scale for an analogue and digital display of the time.
HOUR SATELLITE INDICATION AND TURBINE AUTOMATIC
Four satellites, each carrying three hour numerals, successively parade past the minute rail to display the time. The movement’s automatic winding is regulated by dual air turbines.
PEEK CANOPY
Four satellites, successively reveal themselves from under a sublime guilloche black cover in PEEK (PolyEtherEtherketone).
FORGED-ALUMINUM SATELLITES
At the heart of UR-105 time display four forged-aluminum satellites slowly orbit. Each of these satellites is visible during their 60-minute journey along the minute scale.
CARROUSEL IN ARCAP
The carrousel is a critical component and is made from ARCAP, which has been treated with ruthenium then micro-bead blasted.
DUAL AIR TURBINES
The two turbines visible on the back are coupled to the rotor to regulate the winding system of the watch.
WINDING RATE CONTROL LEVER
The winding mode is adjusted via the small lever. In the “FULL” position, the slightest movement will wind up the mainspring. On "STOP" mode, the winding system is disabled.
