A watch with three instantaneous jump displays and self-timer functions is a masterpiece in energy management
A closer look at this time-lapse self-sounding watch reveals that the second hand jumps from one scale to another, while the gold-plated floral pattern on the gold dial appears quiet and calm. Once the second hand reaches 60 seconds, the minute hand jumps from one scale to the next. Finally, when the window at 12 o’clock is displayed at the hour, it will also jump in sync with the second and minute hands to display the new hour. At that moment, you can also hear a soft spring sound: when the self-sounding jump, the device reminds you of the hourly change with this kind of music. This commemorative watch inherits the hour-jumping digital hour display that was introduced during the 150th anniversary of Patek Philippe in 1989 and pays tribute to the former Ref. 3969 model. This new work also shows the outstanding progress of Patek Philippe’s professional watchmaking technology and craftsmanship in the past 25 years.

The fascinating complication is extremely time-consuming and laborious to produce, and the effort is evident in the 438 beautifully polished parts contained in this delicate 32-650 HGS PS movement.
The jump time display is a highly sophisticated complication. A little off topic: In traditional mechanical clocks, the hands are constantly moving continuously under the drive of a balance wheel. For most mechanical watches, the oscillation frequency of the balance wheel is 21,600 or 28,800 half pendulums per hour, which is equivalent to 6 or 8 oscillations per second. Each time the balance wheel makes a half-swing, it drives the escape wheel to rotate one gear, and this movement is transmitted to the pointer through the transmission gear train. The pointer moves forward gradually. The movement of the second hand clearly shows this forward pace, but the progressive movement of the minute and hour hands is almost imperceptible.

The jumping time self-sounding watch also has a balance wheel, which can complete 8 half swings per second. However, energy is not transmitted directly to the second hand. This energy is stored in a storage device, and it is released to the fourth gear only when the eighth half-swing occurs. By analogy, the energy accumulated within 60 seconds must be transmitted to the minute hand instantly; after 60 minutes, the digital hour display also needs to advance, and the same instantaneous energy transmission process must occur simultaneously. There is a problem: the hour dial is heavier than the hour hand, so it needs more energy to drive. Not only that, the hammer needs to strike the gongs at the hour, so it needs more energy. It can be seen that this watch with three types of instantaneous jump display and self-timer function is a masterpiece in energy management.
Anniversary celebration of the new movement
With the new manual-winding mechanical movement 32-650 HGS PS, Patek Philippe has achieved this extraordinary feat in a unique way. Patek Philippe’s internal R & D workshop lasted four years and finally developed a device that can store the energy required for the instant jump display and accurately synchronize the hour, minute, and second instant jump displays. With this device, Patek Philippe has applied for three patents. The most striking part is the second hand fork lever made of silicon-derived material Silinvar®. The second hand fork lever is connected to a spring that stores the energy generated by the eighth half-swings of the balance wheel. These eight half-swings constitute one second. The beak-shaped front end of the fork rod meshes with the cogs of the Silinvar® gear, which in turn meshes with the fourth gear. After every eight half swings, the fork lever is raised. The cogwheel gear advances by one space, pushing the fourth gear forward about 6 degrees, and then the second hand moves forward for one second. The fork lever and the wolf gear are made of Silinvar®, because this high-tech material is lightweight, and the beak-shaped front end has almost no friction with the wolf teeth, which is extremely efficient. This brings immeasurable advantages to such a huge task for the hour, minute and second synchronous instant jump display. The fourth gear has a snail-shaped cam, which, after each full rotation, drives a ruby pawl to hook the beak-shaped front end. Through a fork, it briefly releases the center wheel, causing it to rotate 6 degrees clockwise at the same time as the fourth gear. This allows the second and minute hands to jump at the same time. After the center wheel makes one full revolution, the hour dial will advance by one division with the jump of the second and minute hands. Since the hour dial has 12-hour numbers for maximum readability, the hour dial advances 30 degrees. While the hour display is beating, it will hit the gong coiled around the movement with the sound hammer, so that it will automatically sound with a gentle spring sound at the beginning of each hour. This is a brand new work that pays tribute to Patek Philippe’s self-proclaimed watch. The brand has today’s extraordinary reputation, and such a complex function device is extremely successful. The slider at 10 o’clock on the side of the case can be used to isolate the hammer to turn off the self-timer function. The fourth patent Patek Philippe applied for this time is this device.

A commemorative model
The latest piece of this Patek Philippe watch masterpiece is paired with a barrel-shaped platinum case, also from the brand’s in-house workshop. Like the dial’s outer edge and minute scale ring, the case is also trimmed with delicate floral engravings. The slider to enable / disable the self-timer function is at 10 o’clock. The fluted platinum crown is embossed with the Calatrava cross star pattern. The watch has a platinum case back and is engraved with ‘PATEK PHILIPPE GENEVE 175e Anniversaire 1839% 2014’.
Patek Philippe Ref. 5275 Time-lapse Swing Watch features a bright black alligator strap with a platinum folding clasp. The buckle is engraved with the ring ‘PATEK PHILIPPE 1839% 2014’ and the center is also engraved with the Calatrava cross star pattern
The eccentric minute scale ring occupies the main position of the upper half of the dial, and the minute hand rotates along the scale ring. The minute scale consists of black Arabic numerals and black dots. The striking small seconds dial features black orbital scales with black Arabic numerals and black nickel-plated Breguet hands. These display designs once again demonstrate the sophisticated craftsmanship and extraordinary quality of Patek Philippe. Since these are instantaneous jump displays, it is also very important to maintain precise alignment in the rest position: the hour number is located in the center of the dial, the minute hand point just points to the minute scale, and the second hand point is in line with the track scale.

Patents and Innovation
Patent: Self-timer isolation device
The innovative isolation device can not only turn off the hour self-sound function, but also completely separate the timekeeping mechanism from the movement.
Patent: instant jumper with coaxial gear (second jumper)
The innovative jump time display device eliminates the need for springs and forks, but precisely controls the jump movement of the second hand through the gear train. It is completely based on the rotational drive of the gear train, eliminating the reciprocating movement of the fork.
Patent: instant jumper with coaxial gear (instantaneous jump hours)
