Considered the beneficiary of Patek Philippe’s 1941 classic Ref. 1518 , the Ref. 5270 Perpetual Calendar Chronograph is now available in another yellow gold version that joins the platinum version with salmon dial that was introduced in 2018.
With the new Ref. 5270J-001 Perpetual Calendar Chronograph, Patek Philippe makes available this combination of complications in a yellow case for the first run through.
Pairing a concave bezel with gadroonedlugs, the 41 mm x 12.4 mm case is water resistant to 30 meters/100 feet. The rectangular pushers are satin-completed on the side, polished on top.
The gleaming opaline dial with applied baton indexes and leaf-shaped hands in yellow gold has the typical layout of Patek Philippe chronographs with perpetual calendar: day and month in a double aperture at 12 o’clock, analog date with an integrated moon-phase indication at 6 o’clock, subsidiary seconds at 9 o’clock, and a 30-minute counter at 3 o’clock.
These displays are complemented with two small round apertures for the day/night indication and the leap year cycle. The tachymeter scale on the boundary of the dial allows speed readings with the chronograph hand.
The sapphire-crystal case back showcases the caliber CH 29-535 PS Q movement, the principal chronograph movement with a perpetual calendar developed completely in the manufacture’s workshops.
Beating at 4 Hz (28,800 vibrations each hour) and composed of 456 parts, this hand-wound movement combines traditional architecture (horizontal grip, column haggle winder) with six patented innovations for the chronograph functions improving accuracy and reliability over time. The power hold is 55 to 65 hours with the chronograph disengaged. An interchangeable solid back in 18K yellow gold is also conveyed.
Completed by a hand-sewed matt chocolate brown alligator strap got with a yellow gold fold-over clasp, the Patek Philippe Ref. 5270J-001 Perpetual Calendar Chronograph has an indicative cost of Euro 155,000. patek com
