Design
- Movement
- The watch is powered by the IWC caliber 401, a hand-wound mechanical movement. The source identifies this movement as an updated iteration of the company's caliber 89. This caliber 401 is positioned as the primary timekeeping component within the R1205 reference case. According to the documentation provided, the watch has recently undergone a service and is reported to maintain time accurately.
- Case and Dial
- The 18K yellow gold case measures 35mm in diameter. The source reports that the case retains presentable dimensions and displays minimal signs of previous usage. A characteristic feature of this specific example is a rosy patina across the gold surfaces, which is interpreted by the source as an indication of minimal polishing performed on the watch during its history. The dial is white and is described as being in a virtually flawless condition. It features applied gold indices and yellow gold hands. The inscriptions on the dial read "International Watch Co. SCHAFFHAUSEN" and "SWISS" at the base. The unsigned crown is noted as being original to the timepiece for this period.
