Swiss luxury watch maker URWERK unveils its latest timepiece UR-105M by paying tributes to the chivalrous knights of the Middle Ages who would risk their lives for honour and glory.

The UR-105M features an impressive titanium body reinforced by steel armour. Equipped with a darkened over-sized crown at 12 o’clock, the case of UR-105M is inspired from the protective clothing of warrior. The visible screws on the bezel not only bring a distinctive esthetic to the watch, but also tack the steel armor onto its titanium body. This shield protects the movement from the outside world’s aggressions.

Controlled by an in house developed manual-winding mechanical movement, its time display boats four revolving satellites that slowly orbit. Each of these satellites is visible during their 60-minute journey along the minute scale. A circular PEEK (Poly Ether Ethercetone) 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.

The UR-105M is available in two versions: the ‘Iron Knight’ with a titanium case and steel bezel and the ‘Dark Knight’ with a titanium case and AITiN-treated steel bezel.
