Urwerk UR-105 (Pre-owned - Good) — USD 51,750 on eBay

The Urwerk UR-105 reference represents a distinct evolution within the brand's "Knight" series, characterized by its unique "CT" (CollectoR) designation. This particular iteration offers a novel approach to displaying the intricate movement, allowing the wearer to selectively reveal or conceal the internal mechanics. This design choice distinguishes it from earlier UR-105 models, which either presented a fully open view or a more restricted display focused solely on the minute track, providing a balance between technical exhibition and visual discretion. The UR-105 CT features a case crafted from titanium and PVD-coated steel, housing the UR 5.02 self-winding movement. The case measures 39.5 mm in width, 53 mm in length, and has a thickness of 17.3 mm. The movement provides a power reserve of 48 hours. A sapphire crystal protects the dial, offering a clear view of the wandering hours display. Water resistance is rated at 30 meters. This reference appeals to collectors who appreciate Urwerk's distinctive approach to time display and mechanical innovation, particularly those who value the option to control the visual presentation of the movement. The UR-105 CT fits into the brand's lineage as a refinement of the wandering hours concept, offering a more interactive experience compared to its predecessors. Its design emphasizes both the technical artistry and the wearer's engagement with the timepiece.
