The Reference 5205 Annual Calendar, originally launched in white gold in 2010, returns in 2022 with a fresh and contemporary olive green dial. This model features the classic day/date/month apertures arranged along an arc, enhanced by a black-gradient rim for added depth. The rose gold case is defined by its concave bezel, hollowed flanks, and skeletonized lugs, all meticulously hand-polished by Patek Philippe artisans. A rose gold frame at 12 o’clock highlights the date, ensuring readability of the Annual Calendar indications. The transparent sapphire crystal reveals the self-winding Caliber 324 S QA LU 24H/206 movement, equipped with the ingenious Patek Philippe Annual Calendar mechanism, which requires only one manual adjustment per year. The 40mm rose gold case, 11.36mm in height, is paired with a hand-stitched, two-tone green alligator leather strap and prong buckle, combining sophisticated craftsmanship with contemporary style.
