of Patek Philippe 6301P Not only symptoms a Great ringtone with a small hour and a minute repeater, which also comes with the patented “Seconde Morte” jumping auxiliary seconds. We delve into the many intricacies of this feature from our archives.
in the world High quality watch making, Nothing is as unique and attractive as a chiming watch. Often described as the ultimate unique complication in watchmaking, only a handful of manufacturers are currently able to produce them in-house. Surprisingly, only a few hundred minute repeaters are estimated to be produced each year in Switzerland, and only a few of them. Great ringtones — Chiming watches that strike full hours and quarter hours automatically. Last November, independent Genevan celebrated Philippe Stern’s 82nd birthday preparation Patek Philippe has added a new member to its already impressive collection of repeater watches. 6301P Grande Sonnery. It has three classic gongs and two patents for the striking mechanism and jumping small seconds at 6 o’clock. It is also the first Patek with a Great ringtone “In its purest manifestation.”
The invention of the chiming clock is usually credited to the English watchmaker Daniel Quare (1647/49 – 1724), but Patek Philippe began producing spectacular watches from scratch. In September 1839, four months after its establishment, the preparation A pocketwatch with repeater (which sells for CHF 450) has already entered the first timepiece of its kind in its journal. In 1850, entries for pocket watches were a Great ringtone It appeared in the same magazines. The catalog of the 1851 “Great Exhibition” in London (the first world exhibition, which attracted six million people from May to October) listed “repeaters” and “watches with automatic strikeworks” as Patek Philippe’s specialties. This was followed in 1860 by Patek Philippe’s first pocketwatches with minute repeaters, then in the 19th century, more timepieces with quarter repeaters, five minute repeaters and minute repeaters. More precisely, the first wristwatch from Patek Philippe with a five-minute repeater, the no. 174603, a ladies’ model with a platinum case in 1916, later the brand’s first wristwatch minute repeater sold in 1925 to Ralph Teeter (August 17, 1890 – February 15, 1982), a blind inventor who later developed the automobile cruise control system.
Fast forward to 1989, the year Patek Philippe celebrated its 150th anniversary: the launch of Caliber 89 also marked the rebirth of Patek Philippe’s chiming watch expertise. Featuring 33 complications, “the world’s most complicated portable mechanical timepiece for over a quarter of a century” is also included Big/small bell and a minute repeater on four gongs. Shortly thereafter, Patek Philippe resumed regular production of repeaters, and today, each one is personally inspected by Thierry Stern, Patek Philippe’s president and chief executive, before leaving the workshops.
A new movement derived from Caliber 300
For the 6301P, Patek Philippe obviously had to develop a new movement. As a starting point, the team chose the caliber 300 in the Grandmaster Chime (ref. 5175, introduced in 2014, the most complicated wristwatch movement Patek Philippe has ever produced). Consisting of 703 parts (by comparison, Grandmaster Chime’s Caliber 300 has 20 complications and 1,366 parts), the new manual-wind caliber GS 36-750 PS IRM (diameter: 37 mm, height: 7.5 mm) is equipped with two TTs. – Twin connected mainspring barrels, one for the traveling train and the other for the chiming mechanism. This set-up provides a power reserve of 72 hours for the movement and 24 hours for the strikework, which allows the watch to strike full hours and quarter hours throughout the day and – due to the uniform torque characteristic – also provide optimized sound intensity. Two twin mainspring barrels are pushed into the crown and rotated clockwise to rotate the traveling train and counterclockwise to close the strikework. All four mainsprings have slip bridges to prevent over-tension. Patek also opted for a silicone hairspring, which shows both of preparation A commitment to the use of high-tech material, but clearly designed in its essence and decorated in a more traditional style highlights the difference between the watch and the movements.
When it comes to strikework, perhaps the world’s first “push notification”, Patek Philippe chose three classic gongs – low, medium, high. This technology option requires more power than typical systems with two gongs. This complicates the watchmaker’s job as he tunes each gong until all three create the desired sound. Attached to the movement, the three gongs must not touch each other or the case or other parts of the movement despite the compact space in which they hover. Three hammers of the same size and mass provide a uniform strike for all three pitches. Bells are struck on a low-pitch gong, while quarter bells are struck with a three-strike high-low-medium sequence. The first quarter hour (15 minutes) melody is played once, the second quarter hour (30 minutes) twice and the third quarter hour (45 minutes) three times. Each quarter-hour sequence is automatically preceded by the number of hours elapsed and followed by the number of quarter hours. Thanks to the energy stored in the strikework’s twin mainspring barrel, it added up to an impressive total of 1,056 strikes in 24 hours. 6301P owners can also select a strikework mode small bell; It strikes full hours but omits the repetition of hours when striking quarter hours. In Silence mode, the automatic time strike is switched off completely.
Strikework mode selection is handled by a slide switch on the caseband at 6 o’clock. The small hour The mod is left leaning Great ringtone Mode in the middle and silence on the right. This unique feature is the subject of a patent already developed for the Patek Philippe Grandmaster Chime and describes a mechanism that enables selection and activation of the strike mode with a single slide switch. Previously, two switches were required to perform these steps. Another patent, also developed for the Grandmaster Chime, allows it to be completely isolated Great ringtone In silence mode, eliminates power consumption. On request, the minute repeater can be triggered by pressing the pusher in the crown at 3 o’clock. In response, it struck the number of hours with low tones, the quarters with three-strike sequences (as in Great ringtone mode), and, on a high-pitched gong, the number of minutes that have elapsed since the last quarter hour. The minute repeater can be triggered at any time, even if the slide is set to silence mode.
According to Patek, one of the challenges was integrating a small jumping seconds display at 6 o’clock, which had never been done before. Big ringtone. Based on four patents of the 175th anniversary model, Ref. 5275 Chiming Jump Hour, the 6301P does not rely on jumper springs as usual, but instead comes with wheels and a release lever that instantly unblocks the wheel train every second, making it easy to control and control energy consumption.
When we asked Thierry Stern about the biggest challenge the 6301P posed, he didn’t have to think long: “Definitely the sound. It’s always a big challenge, especially for this one. With three gongs, finding perfect harmony isn’t easy. Each of the gongs is very easy to do alone, but when you put all three of them together in one instance and they don’t touch each other and they have to be completely in the same harmony, especially in the quarter, it’s really a challenge. And there I was happy to have, I can say, a lot of experience, really thanks to my father [Philippe Stern]. Because when I started at Patek, I was 19, the first thing he did was take me to those validation meetings when he had to listen to the minute repeaters. Since then I’ve been listening to them a lot, and today I can find new ideas, you know. I can, but I’m very good at imagining how far we can go and what we should try. And that is a very beautiful challenge; With this watch, for example, we found some new essays and some new ideas about how to improve the sound, and that’s a very important thing. Because at the end of the day, when you buy a minute repeater, we all listen to that piece and say, ‘That’s cool,’ or; You don’t have to be a professional, you know, to write an essay, which is something not all of us can do. But to listen to music and say ‘this is good’ or ‘not good’, we can all do it. So it’s really a challenge, you know, to find the perfect harmony that fits the watch, especially in a platinum case. But that’s my point, that’s my goal – to say, ‘We can do this.’
