Patek Philippe introduces a new version of its Annual Calendar Regulator in rose gold, paired with a unique two-tone dial in graphite and ebony-black featuring a vertical satin finish. The watch is powered by the caliber 31-260 REG QA self-winding movement, specially designed for this model, which incorporates a high-tech regulator with a Pulsomax escapement and a Spiromax balance spring in Silinvar - both developed by the "Patek Philippe Advanced Research" department. The regulator-style display includes hour and seconds subdials, sweep minutes, and day, date, and month apertures. The watch comes with a rose gold case, sapphire crystal case back, and is water-resistant to 30 m, with a diameter of 40.5 mm and a height of 10 mm. The alligator leather strap with square scales is hand-stitched and comes in a matte black color with a prong buckle.
