This is my deep insight into the Patek Philippe Grandmaster Chime Ref. 5175

 

 

The Grandmaster Chime is a striking example of the “intelligent watch” as envisioned by Patek Philippe’s philosophy. To protect complicated timepieces against damage caused by inadvertent manipulations, the manufacture’s engineers devised clever “isolators” that interrupt the flow of power between individual mechanisms or block certain functions while others are active. The engraved inscriptions and symbols on the case and the pushers are further hallmarks of convenience that make the Grandmaster Chime a self-explanatory grand complication watch.

The Grandmaster Chime automatically sounds the hours and quarter-hours at each quarter hour (in the Petite Sonnerie mode only the hours at the top of the hour and only the quarters at each quarter hour). It ranks among the functions that aficionados and collectors hoped to see implemented in a Patek Philippe wristwatch. But it was always clear to the manufacture that this would not happen unless a strikework power reserve of at least one entire day could be achieved. The necessary technology was not available until just recently. But now, thanks to the double barrels reserved for the strikework mechanism, the sonneries can be activated during a period of more than 30 hours before they need to be rewound by hand. Remarkably, this was accomplished even though the quarter-hours are sounded not on two but instead on three gongs with different tone sequences. This requires 50 percent more energy for each quarter-hour strike.

Minute repeater and alarm

The strikework double barrels also deliver the energy for the minute repeater, which on demand strikes the hours and quarter-hours as well as the minutes that have elapsed since the last quarter-hour. It was the Genevan manufacture that orchestrated the comeback of this queen of complications 25 years ago. The alarm strikes the alarm time by reproducing the complete tone sequence of the minute repeater, with exactly the same sound quality. This is a function never before integrated in a mechanical wristwatch.

  • Many thanks Alex , this is the best watch I have ever seen ,and without you Alex we would have never seen it , Thanks again mate.

  • It’s a very fabulous Watch! What about the feature Crown position indicator (RAH)?

  • this is an accomplishment of epic proportions. kudos to Thierry Stern and the entire Patek team. they have, once again, significantly raised the bar of haute horlogerie from every conceivable angle from concept design all the way through to case fabrication and assembly.

  • There is a saying, “We did it because we could.” The watch is a tour de force in its every aspect. As you say, “Chapeau!” The dimensions are small for all the mechanical complexity. The casework is of another era beautifully and deeply carved.
    I am still happy with PP Calatrava in 18K yellow gold.

    Thank you, Alexander!

  • Alex ,why are they giving out all the details of this unique watch ?
    It makes it easier for the competition to duplicate a similar piece

    • Though Patek Philippe is giving out all details of this truly awe-inspiring watch, how many watch brands have capability to create such a stunning timepiece?

      Well Roger, I think very few watch companies can create some watch that is similar to Patek Philippe Grandmaster Chime Ref. 5175. Maybe, Lange, JLC and Vacheron Constatin can create something like this.
