Lot Essay

Urwerk is offering the new owner a free servicing of the present watch at the firm’s workshops in Switzerland.

The UR-105M features an impressive titanium body reinforced by steel armor. At the heart of its time display four satellites slowly orbit. Each of these satellites is visible during their 60-minute journey along the minute scale. A circular PEEK (PolyEtherEthercetone) canopy with openings enhances the current hour. Once the hour has elapsed, the satellite – guided by a Geneva cross – rotates and continues around its orbit for another three hours before returning to the center stage. Completing the indications, running seconds and power reserve are displayed laterally on the case band.

At the back of the UR-105M, URWERK’s signature ‘Control Board’ houses additional displays and functions: an ‘Oil Change’ indicator alerting when it is time for a service; 42-hour power reserve indicator; plus the fine-tuning screw allowing adjustment of the rate.
