Patek Philippe has unveiled its new Annual Calendar Regulator with a series of fresh ideas and surprises. It is claimed to be the first of the brand to have a wristwatch with a regulator dial, with a sweep minute hand, a subsidiary hour dial at 12 o’clock and a seconds subdial at 6. The Patek Philippe Ref. 5235 Annual Calendar Regulator features a caliber 31-260 REG QA, and Silinvar components, a high-tech material derived from silicon. The Annual Calendar shows off the month, day, and date in apertures as well as an all-new oscillator. The brand is well-known for its 240 movement with 22 carat gold mini-rotor recessed in the main plate and its new self-winding caliber is expected to draw more interest.
The timepiece will boast a case with the Calatrava silhouette and a three-part ensemble with the bezel, band, and back in 18 carat white gold. It also sports a hand-stitched night-blue alligator strap with square scales and an 18 carat white-gold prong buckle which is engraved with the Patek Philippe signature. The wristwatch also has a sapphire-crystal glass protecting the large aperture with three concentric circles showing the day, month and date. The dial has the Patek Philippe Geneve signature engaved as well.
