Even if you doubt that complicated mechanical wristwatches appeal to women, you cannot deny the allure of the Patek Philippe Annual Calendar. The automatic movement addresses the notion that women do not care to wind their watches. For those who prefer not to set them, the annual calendar mechanism requires adjustment just once a year. Best of all, the ladies’ Annual Calendar Ref. 4936 translates the original men’s design fluidly into a feminine piece with a mother-of-pearl dial and a bezel set with small diamonds. The detailing is impeccable, and, as with all timepieces from this brand, this quality carries over to the inside of the watch, where a patented movement will draw admiration from watch lovers of both genders.
