The Patek Philippe Annual Calendar Ref. 5205G-013 is a sophisticated timepiece that seamlessly combines functionality with elegance. Encased in 18K white gold, it features a striking blue sunburst dial that gracefully transitions to black, complemented by gold applied hour markers. The watch showcases a unique design with three apertures along an arc to display the day, date, and month, while a sub-dial at 6 o'clock indicates the moon phase and 24-hour time. Powered by the self-winding Caliber 324 S QA LU 24H/206 movement, it offers an annual calendar function, requiring adjustment only once a year. The 40mm case is water-resistant up to 30 meters and is paired with a black alligator leather strap secured by an 18K white gold prong buckle. This timepiece exemplifies Patek Philippe's commitment to precision and timeless design.
