ZENITH Captain Power Reserve
ZENITH Captain Power Reserve is an Ultra-thin automatic watch with power reserve and date indicator. The power reserve was one of the vital functions of marine chronometers upon which the precise calculation of longitude depended. On board, this instrument was treated with exceptional care; the survival of the whole crew depended on its precision.
For the person in charge of its maintenance, the power reserve function meant that the rewinding could be optimized by knowing the precise tension of the barrel spring. This useful function appeared very early in the history of the ZENITH Manufacture, which registered an initial patent as early as 1910 to protect this exclusive system.
The Zenith Captain Power Reserve is equipped with an ultra-thin movement only 4.675 mm thick, with the power reserve indicator positioned at two o’clock and the date at six o’clock.
This timepiece is available in three versions with a silver or black “Clou de Paris” guilloché dial, in a steel case or with a silver dial in an 18-carat rose gold case.
