Patek Philippe Superior Analysis 5750 Minute Repeater

Based in 2005, Patek Philippe‘s “Superior Analysis” division goals at bettering mechanical actions and bringing progressive options within the fields of supplies (silicon, as an illustration) and applied sciences for watchmaking. This goes for the introduction of Silinvar (2005), the Spiromax steadiness spring (2006), the Pulsomax escapement (2008), the Oscillomax ensemble (2011), and an additional optimized model of the Spiromax steadiness spring (2017). In 2017, the model will take a look at one thing totally different, and that’s a compliant mechanism for the dual-time operate, in an Aquanaut. In the present day, following a 12 months with already a grande sonnerie watch, the model continues its researches within the area of chiming watch, with main enhancements on the minute repeating watch, with the brand new Patek Philippe Superior Analysis 5750 Minute Repeater. 

The technical options

The purpose of the Superior Analysis division is to carry new options with a purpose to innovate, or within the current case to enhance current mechanisms. For this new introduction, the workforce in cost has been engaged on the chiming watch, a speciality of the model that counts a number of repeating watches in its assortment. The bottom for this watch is current, because the motion takes on the basic Calibre R 27 that the model launched in 1989. The thought with this new Superior Analysis 5750 Minute Repeater was “to amplify the amount of the time strike in a purely mechanical method whereas preserving the superb acoustic high quality in addition to the smallest attainable dimensions.” Protecting the bottom of the present calibre, the watchmakers of Patek created a brand new module that works like a mechanical loudspeaker.

Normally, amplification of the sound does depend on a versatile diaphragm which just like the pores and skin of a drum is connected alongside its periphery. However right here, Patek Philippe created one thing totally different… As an alternative of a membrane, the system for which Patek Philippe registered three patents has an oscillating wafer manufactured from artificial sapphire with a thickness of 0.2 mm. Because of its angular movement, this inflexible and freely movable wafer offers clearly higher sound propagation for the confined quantity of a wristwatch. Plus, this permits to retain the sapphire caseback and thus the likelihood to admire the motion.

To realize sound transmission from the gongs of the minute repeater to the sapphire-glass oscillating wafer, the engineers developed a system with a metal sound lever that’s connected in the midst of the oscillating wafer. “The opposite finish of this sound lever that resembles a tuning fork encompasses a versatile attachment with a thickness of 0.08 mm. When the hammers strike the gongs, their oscillations are transmitted to the sound lever which in a primary part amplifies them and transmits them to the inflexible oscillating wafer the place they’re additional amplified. The angular movement of the oscillating wafer excites the air layers above and beneath the sapphire glass, producing a noticeably louder sound,” explains the model about this so-called fortissimo “ff” amplifier module.

With the Patek Philippe Superior Analysis 5750 Minute Repeater, the model additionally labored on the propagation of the sound, along with amplifying it. Classically in a repeater watch, the sound of the hammer placing the gongs is propagated by the complete watch – on all sides of the case, on the again and thru the crystals. It’s why the fabric chosen for the case is of nice significance – and titanium and metal are recognized to offer higher sound than gold or platinum, on account of decrease density. Particularly, the latter is essentially the most difficult for a minute repeater. Within the minute repeater with the fortissimo module, an insulation rim manufactured from a high-tech composite materials acoustically uncouples the amplifier from the motion. The sound is first routed to the sound lever after which to the oscillating wafer and subsequently propagated by 4 openings at 12, 3, 6, and 9 o’clock in a titanium ring. The sound waves exit by a slender slot between the caseback and the caseband – there’s a mud filter to guard the motion. Thus, the case materials has no extra affect on the sound of the watch. So, even when this watch would later are available yellow, white or rose gold, its sound will probably be similar.

Some work has additionally been performed by the Patek Philippe Superior Analysis workforce on the loudness of the sound, but additionally on the standard, richness and musicality of the minute repeater. As an example, the size of the strike has been elevated to ensure that the gongs to fade considerably longer. Some evolutions have been performed on supplies too. Classically, hammers are manufactured from metal however on this Superior Analysis 5750 Minute Repeater, they’re manufactured from platinum – a patented resolution that improves the standard of the strike. Additionally, a minirotor in platinum replaces the eccentrically recessed minirotor in 22K gold. Because of the better materials density, it delivers the identical winding energy with a thinner design.

The Patek Philippe 5750P Minute Repeater

The brand new Calibre R 27 PS and its 4 patents are housed in a watch that exhibits novel design components, but a typical Patek form and really feel. A restricted version of solely 15 items, the 5750P is a basic mannequin, with a 40mm diameter, a form that remembers earlier repeater fashions from the model – particularly the 5178 minute repeater with cathedral gongs – with its rounded casebands and stepped lugs. It’s a reasonably skinny watch, with a top of 11.1mm. And if these components are basic, the dial is way bolder however no much less spectacular.

The design of the dial is a 5-part component with “an openworked motif impressed by the spoked wheels of classic cars” that stands out in opposition to a black background with a snailed sample. Intricate and complicated, the identical motif is repeated on the small seconds, which is a rotating disc with a small marker that serves as a hand – which creates a dynamic impact on the watch. Time is indicated by flat Dauphine arms in white gold and utilized kite-type hour markers in blackened white gold.

The again reveals the in-house Calibre R 27 PS, with its basic (perceive not cathedral) gongs and, after all proper within the center, the sound lever within the form of a tuning fork that carries the clear oscillating wafer of the fortissimo amplifier system. This 3Hz, automated motion is supplied with the entire model’s applied sciences, together with the Gyromax steadiness spring in Silinvar launched in 2006. All of the components are finely embellished, with Geneva stripes, bevels and a platinum micro-rotor with a ray sample within the type of the dial, created with a laser-based light-absorbing floor texturing method that enables sure segments to seem black.

Availability & Worth

The Patek Philippe Superior Analysis 5750 Minute Repeater is worn on a daring, shiny orange alligator strap with contrasting black stitching, closed by a platinum fold-over clasp. It’s a restricted version of 15 items solely, priced at CHF 590,000 – clearly not low cost for a minute repeater, however way more accessible than a Tiffany-blue Nautilus 5711… and way more advanced!
