Urwerk’s UR-105M Iron Knight is inspired by the Middle Ages, an era of lances, legends, chivalrous conduct, and noble deeds. The UR-105M embodies an era when knights in shining armor who would risk their lives for honor and glory.

All of Urwerk’s iconic codes are present in the UR-105M. Satellite hours gliding slowly along the minute scale, darkened over-sized crown at 12 o’clock, and a subtle technical feel. 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. 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; a 42-hour power reserve indicator; plus, the fine-tuning screw allowing adjustment of the rate.
