Introducing: Patek Philippe “Advanced Research” FORTISSIMO 5750P

Patek Philippe “Advanced Research” The manufacture presents a pioneering innovation for one of its most significant fields of competence – chiming watches.
The engineers at Patek Philippe “Advanced Research” have extended the horizon of its chiming watches by developing a totally new all-mechanical sound amplifying system. This fortissimo “ff” module consists of a flexibly suspended sound lever and an oscillating wafer made of transparent sapphire-crystal glass. In comparison with conventional minute repeaters and regardless of the case material, it delivers clearly amplified sound of excellent acoustic quality. Crowned by four patents, the pioneering technology is presented in the Ref. 5750 “Advanced Research” minute repeater, a special limited edition consisting of 15 watches cased in platinum and endowed with a unique dial design.

The spirit of innovation has been in Patek Philippe’s DNA since the company was founded. True to this uninterrupted tradition, the manufacture has spared no effort to further push the limits of watchmaking artistry and move at the forefront of technical development. But Patek Philippe considers innovations to be meaningful only if they offer the user genuine added value in terms of quality, precision, and dependability in the long run. Founded in 2005, the Patek Philippe “Advanced Research” department has meanwhile been integrated in the Research & Development division and vested with the task of pursuing high-end research in the fields of new materials, technologies, and conceptual fundamentals intended to open totally new perspectives in the domain of watchmaking. To attain these objectives, the manufacture has established unique competencies, called together its best specialists, and provided them with the latest technical resources, including instruments required for computer simulation. The engineers at Patek Philippe “Advanced Research” also collaborate with independent external research facilities such as the Centre suisse d’électronique et de microtechnique de Neuchâtel (CSEM) or the Federal Institute of Technology Lausanne (EPFL).

Since 2005, Patek Philippe “Advanced Research” has stood out with pioneering work in the innovative field of Silinvar®, a derivative of silicon with phenomenal characteristics for watchmaking applications (temperature compensating, lightweight, lubricant-free, antimagnetic, etc.). Concurrently, the manufacture presented the first escape wheel in Silinvar® (2005), followed by the Spiromax® balance spring (2006), the Pulsomax® escapement (2008), the Oscillomax® ensemble (2011), and a further optimized version of the Spiromax® balance spring (2017). Each of these technology leaps was accompanied by the launch of a wristwatch in limited editions that were the first to be endowed with the innovative components. In the meantime, most of the movements for the current Patek Philippe watch collections are equipped with Spiromax® balance springs made of Silinvar®.

In 2017, in a totally different field of research, Patek Philippe “Advanced Research” developed a compliant mechanism (system with flexible articulations) made of conventional horological steel that in Patek Philippe watches with two time zones is used to set the second time zone. This technical innovation was launched in the limited-edition watch that also first featured the optimized Spiromax® balance spring.

A limited edition of 15 watches
To present the exclusive system of sound amplification and propagation, Patek Philippe is launching a limited special edition of the watch as was the case previously with the “Advanced Research” innovations. The Ref. 5750P Patek Philippe “Advanced Research” minute repeater comes in a sleek case with a slightly domed bezel. It is inspired by the Ref. 5178 minute repeater with cathedral gongs, has the same diameter of 40 mm. However, with a height of 11.1 mm, it is 0.57 mm thicker. To demonstrate the efficiency of the fortissimo system, the manufacture opted for the material that poses the greatest acoustic challenges – 950 platinum.
In its center, the five-part elaborately constructed dial features an openworked motif inspired by the spoked wheels of vintage automobiles. It stands out against the black background with snailed spiraling lines. The subsidiary seconds at 6 o’clock consists of a rotating disc with the same openworked motif against a black snailed background and a small marker that serves as a hand – a movable element which creates a unique, dynamic effect. The time is indicated by flat Dauphine hands in white gold and applied kite-type hour markers in blackened white gold.
