Collectors seek this reference for its 40mm stainless steel case and the Calibre 936 automatic movement, which integrates a second time zone sub-dial at 6 o’clock synchronized with a rotating 24-city world time disc. The silver sunray dial features a power reserve indicator at 10 o’clock and a pointer date at 2 o’clock, offering a high level of functional density within the Master Control aesthetic. This model is noted for its 1000 Hours Control certification, ensuring rigorous testing for accuracy and durability. On the secondary market, this reference typically trades between $6,500 and $9,500 depending on condition and the presence of original documentation. A notable production detail is the use of a dedicated crown at 10 o’clock to adjust the city ring independently of the primary time setting.", "score": 203}]}
