Pre-owned Patek Philippe Complications Annual Calendar ref 5146G-001 (2016). Patek Philippe developed the annual calendar complication in 1996. It has since become a pillar of the brand’s catalog, appearing on the pre-owned Patek 5146G-001 for sale here today. This watch is elegant yet practical and transcends time and fashion. Although this Patek is discontinued, you can add it to your collection right now in excellent secondhand condition. Features include the date for months with 30 and 31 days, which only needs to be adjusted once per year at the end of February. Compare that to the regular Patek calendar, which needs to be adjusted 5 times a year, and the Perpetual calendar, which never needs to be adjusted at all. It’s an ingenious complication that will marvel you year after year. Ref. 5146G-001 is a white gold edition of the Patek Complications Annual Calendar with a stunning cream dial and brown leather bracelet. Shop Patek Philippe Complications Collection
