Patek Philippe Introduces Grande Sonnerie Ref. 6301P



A MASTERPIECE OF MINIATURIZATION AND ACOUSTIC PERFECTION.


This grand complication, exceptionally rare in a wristwatch, is complemented with a petite sonnerie (that does not strike the quarter hours), a minute repeater (that strikes on demand), and with a patented jumping subsidiary seconds. The Ref. 6301P Grande Sonnerie has a new 703-part movement, cased in platinum as well as a black dial in grand feu enamel; it will round out and recrown the unique collection of Patek Philippe repeater timepieces.



PATEK PHILIPPE, THE GRAND MASTER OF CHIMES


To implement the grande sonnerie as envisioned, Patek Philippe developed a new movement as a spin-off of the caliber 300 of the Grandmaster Chime. Given its 703 parts, the caliber GS 36-750 PS IRM is remarkably compact for such a complex mechanism (diameter: 37 mm; height: 7.5 mm). One of the traditionally greatest difficulties for the engineers of grande sonneries is mastering energy flows and power reserves. Unlike in minute repeaters which must be triggered on demand by actuating a slide or a pusher, the grande sonnerie needs to have sufficient reserve power to automatically sound the required number of time strikes with uniform acoustic quality.


A three-day power reserve for the movement is what can be expected of a modern watch that is worn daily, in keeping with the customer-centric creation philosophy of Patek Philippe. The 24-hour power reserve for the strikework allows the watch to strike the full hours and the quarter hours during an entire day and thanks to a uniform torque characteristic to assure optimized sound intensity.


MODERN & ELEGANT


The platinum case expresses subtlety and balance in its curves and rounded contours, with the concave bezel for a perfect transition from the slightly cambered sapphire-crystal glass and the countersunk satin- finished case flanks. Like all Patek Philippe platinum cases, it sports a small diamond set in this instance at 12 o’clock because the usual 6 o’clock position is occupied by the slide switch for selecting the strikework mode.
