In the new Grand Complication Minute Repeater Retrograde Perpetual Calendar, Patek Philippe – one of the best luxury watch brands and brands good for investment takes a further step by combining a retrograde perpetual calendar to a minute repeater and offering a view of the complex mechanisms through a transparent sapphire dial.
The 43 mm x 13.3 mm rose gold case is enhanced by white gold inserts, engraved with a “leaf” pattern, and 80 baguette-cut diamonds (~6.22 cts) to decorate bezel, lugs and fold-over clasp. The “leaf” motif is used also for the slide on the left that activates the minute repeater.
To display day, month and leap-year cycle, Patek Philippe uses very thin transparent sapphire disks, with three gold apertures framing white indications that become clearly readable against a black background.
In order not to obstruct the view of the movement, the leaf-shaped hands in black lacquered white gold are skeletonized. The current date is indicated, on a scale around the dial circumference, by a hand tipped by a red half-moon.
The perpetual calendar indications are completed, at 6 o’clock, by a moon phase display integrated by running seconds. The sapphire crystal caseback showcases the 3 Hz (21,600 vph) caliber R 27 PS QR LU and the minute repeater mechanism striking on two gongs. The “leaf” motif is repeated in the off-center rose gold mini-rotor. Comprised of 517 meticulously-finished components, this self-winding movement offers a power reserve of 38 (min) to 48 hours (max).
Patek Philippe provides the price of the Grand Complication Minute Repeater Retrograde Perpetual Calendar on request. So, you can expect it could be one of the most expensive watches in the world.
