A new technology project aimed at improving the sound of the minute repeater.
Patek Philippe's "Advanced Research" department was established in 2005 to improve mechanical movements and bring innovative solutions in the fields of materials (such as silicon) and watchmaking technology. This applies to the introduction of further optimized versions of Silinvar (2005), Spiromax hairspring (2006), Pulsomax escapement (2008), Oscillomax ensemble (2011) and Spiromax hairspring (2017). In 2017, the brand will be looking at something different, and that is the compatibility mechanism of the dual-hour function in Aquanaut. Today, one year later, with a Grande Sonnerie, the brand continues its research in the striking world, with major improvements in the minute repeater, with the launch of the new Patek Philippe Advanced Research 5750 Minute Repeater.replica Felipe Massa watches
technical solutionsThe goal of the Advanced Research Unit is to bring new solutions to innovate or, in the current situation, to improve existing mechanisms. For this new launch, the team in charge has been working on the striking timepiece, a signature product of the brand, whose collection includes several repeating watches. The basis for this watch is existing, as the movement features the classic Calibre R 27 that the brand introduced in 1989. The idea of this new Advanced Research 5750 minute repeater is "to amplify the volume of the time strike in a purely mechanical way while maintaining excellent acoustic quality and as small a size as possible." While retaining the existing movement, Patek Philippe's watchmaking The division created a new module that works like a mechanical speaker.
Generally, the amplification of sound does rely on a flexible diaphragm that is connected along its periphery like the skin of a drum. But here Patek Philippe has created something different... Patek Philippe's three-patented system does not use a diaphragm, but an oscillating wafer made of synthetic sapphire with a thickness of 0.2 mm. Due to its angular motion, this rigid and freely movable wafer provides significantly better sound transmission for the limited volume of the watch. In addition, this preserves the sapphire caseback, allowing the movement to be admired.Richard Mille RM 11-03 Le Mans Classic
To enable sound transmission from the minute repeater gong to the sapphire glass vibrating plate, engineers developed a system with a steel tone rod attached to the middle of the vibrating plate. “The other end of this tuning-fork-like rod has a flexible attachment with a thickness of 0.08mm. When the hammers strike the gongs, their vibrations are transmitted to the rod, which amplifies them in the first stage, and pass them on to a rigid oscillating wafer, where they are further amplified. The angular motion of the oscillating wafer excites the layers of air above and below the sapphire glass, resulting in significantly louder sound," the brand explains about the so-called fortissimo "ff "Amplifier Module.
With the Patek Philippe Advanced Research 5750 Minute Repeater, the brand is committed to sound transmission in addition to amplifying it. In a classic minute repeater, the sound of the hammer striking the gongs is heard throughout the entire watch - all sides of the case, case back and crystal. This is why the material chosen for the case is very important - titanium and steel are known to provide better sound than gold or platinum due to their lower density. Specifically, the latter is the most challenging for the minute repeater. In the minute repeater module with fortissimo, an insulating edge made of high-tech composite material acoustically separates the amplifier from the movement. The sound is transmitted first to the tone rod, then to the oscillating wafer, which then travels through four openings in the titanium ring at 12, 3, 6 and 9 o'clock. The sound waves are emitted through a narrow slot between the caseback and the strap – there is a dust filter to protect the movement. Therefore, the case material no longer has an effect on the sound of the watch. So even if the watch later comes in yellow, white or rose gold, it will sound the same.replica McLaren watches
The Patek Philippe Advanced Research Team also did some research on the loudness of the sound and the quality, richness and musicality of the minute repeater. For example, the length of the strikes has been increased to allow the gongs to fade a little longer. Some improvements have also been made in materials. Hammers are traditionally made of steel, but in this Advanced Research 5750 Minute Repeater, they are made of platinum - a patented solution for improving strike quality. Additionally, the platinum micro-rotor replaces the 22k gold eccentric recessed micro-rotor. It provides the same winding power in a thinner design due to higher material density.
Patek Philippe 5750P Minute RepeaterThe new Calibre R 27 PS and its four patents are contained in a watch that exhibits innovative design elements and a typical Patek Philippe look and feel. Limited to 15 pieces, the 5750P is a classic model with a diameter of 40mm and a shape reminiscent of the brand’s previous minute repeater models – notably the 5178 minute repeater with cathedral gongs – with a round shape Case and stepped lugs. This is a fairly thin watch with a height of 11.1mm. If the elements are classic, the dial is much bolder, but no less impressive.fashion replica watches
The design of the dial is a 5-part element with "a skeletonized pattern inspired by the spoked wheels of vintage cars" that stands out against a black background with a snailed pattern. The same pattern is repeated on the intricate and intricate small seconds hand, a rotating disc with small markers that serve as hands - giving the watch a dynamic effect. The time is indicated by flat toffee hands in white gold and kite-shaped hour-markers in black white gold.
The back shows the internal Calibre R 27 PS, with its classic (not cathedral) gongs, and of course right in the middle, the tuning-fork-shaped rods carry the fortissimo amplifier's transparent oscillating wafer system. This 3Hz self-winding movement is equipped with all the brand's technologies, including the Silinvar Gyromax balance spring introduced in 2006. All parts are meticulously decorated, the platinum micro-rotor dial with Geneva stripes, bevels and radial patterns is made with a laser-based light-absorbing surface texturing technique that renders some parts black.replica watches review
