The Patek Philippe Annual Calendar Regulator ref. 5235G-001 was the first Patek Philippe regulator watch from this manufacture released in 2012 and discontinued in 2018. Today, at Baselworld 2019 Patek Philippe revisits the unique style of its Annual Calendar Regulator by presenting it in rose gold, paired with a two-tone dial in graphite and ebony-black with a vertical satin finish. This exceptional timepiece fitted with a 40.5 mm white gold case and an in-house movement, is pure perfection at its best. Not one of the most popular references from Patek, nonetheless an amazing piece we are happy to see back.
