World Time Chronograph Patek Philippe Ref. 5930 Watch Collectors And Enthusiasts Long-awaited Rare Combination
Since the glimpse of the great fortunes of the 1940s, watch connoisseurs can finally witness once again the harmonious integration of two Patek Philippe’s long-established complex functions-Ref. 5930 World Time Chronograph. The debut of this watch masterpiece is bound to arouse the interest of top watch collectors and enthusiasts. From hand-wound chronographs with horizontal clutches and the world’s thinnest double-star column-wheel two-second chronograph, to single-button chronographs with minute repeater and perpetual calendar functions, Patek Philippe’s chronograph series is still the world’s The most eclectic collection of watches. At the same time, Patek Philippe’s world time series watches are unique among similar watches with their extraordinary patented time zone device and unparalleled aesthetic design. Today, the Patek Philippe World Time Chronograph Ref.5930 perfectly combines these two complementary functions.
Prior to this, Patek Philippe only created a world time chronograph watch more than 70 years ago. That is the No.862442 watch (present in the Patek Philippe Museum, exhibit number: P996), which came out in 1940, and its dial was also equipped with pulsometer and respirometer scales. It was probably owned by a doctor at that time. The birth of Ref.5930 means that Patek Philippe officially incorporated the world time chronograph watch into the regular series and injected it with the cutting-edge technology of the 21st century. This is undoubtedly a bold exploration, since 1940, whether it is Patek Philippe’s world time watch or chronograph watch, has made progress across the ages. Up to now, both mechanical devices have been very precise and more complicated, so it is naturally more difficult to integrate these two complex functions in the same movement.
A new world of micromechanics
The development of a “sunset” chronograph that always displays the time in all 24 time zones is definitely an adventure in the spatial arrangement of the watch. The classic World Time watch does not have a second hand, but the chronograph has a slender direct-drive second hand and a 30-minute counter. Most traditional chronographs are equipped with a dial divided by seconds, while world time chronographs also need a rotating city disk with the names of 24 cities representing each time zone, and a 24 hour Scale ring to indicate the time of the corresponding city. Therefore, on the dial of the World Time Chronograph, there are multiple parts in motion at the same time, and its precise operation cannot be achieved without the coordination and cooperation of internal mechanical devices (automatic winding chronograph movement and World Time mechanism). This undoubtedly made it more difficult to explore the manufacturing process of world time watches. According to the requirements of the Patek Philippe mark, thinner and more elegant watches are more superior, and automatic winding watches are no exception. At the same time, Patek Philippe will never compromise on quality and movement accuracy in order to pursue the thinnest. That’s why every brand new Patek Philippe watch has to undergo months of meticulous testing. Only in this way can it ensure its long-term reliability and accurate timekeeping. The new world time chronograph Ref. 5930 has passed all rigorous tests.
A strong combination of two famous mechanical devices
The new CH 28-520 HU mechanical movement comes from the CH 28-520 PS self-winding chronograph movement with star wheel control and vertical clutch, and the world made according to the idea of Geneva watchmaker Lousi Cottier in the 1930s Time module. Patek Philippe further optimized this device and was patented in 1959 and 1999 with two major improvements.
The Ref. 5930’s chronograph and World Time device have been improved in various aspects to make them even better. The axis position of the CH 28-520 HU movement has moved, the splint has been thinned and redesigned, and the gap between the components has also changed-in this sense, it is a veritable new movement. It not only inherits Patek Philippe’s proud watchmaking tradition, but also demonstrates the innovative technology and functions of a new generation of movements. Its operation mode also continues Patek Philippe’s consistent concept of convenient operation. The button at 2 o’clock is used to start and stop the timing function, and the button at 4 o’clock is used to reset or return to the chronograph hands. If the button at 4 o’clock is pressed while the chronograph hand is running, the hand will return to the zero position and a new timing will start automatically. The chronograph hand is driven by a vertical clutch, so it can also be used as a continuously running second hand without affecting its own durability, the running accuracy of the watch and its power reserve.
Global time in one hand
The world time function is also very convenient: the hour and minute hands indicate the time in the time zone of the city at 12 o’clock on the dial. The time in the other 23 time zones can be quickly ascertained through the city disc and the two-color 24-hour graduated ring indicating the day and night of the corresponding city time zone. When you enter an adjacent time zone from a certain time zone, just press the button at 10 o’clock to adjust it. Every time the city disc and the 24-hour scale ring are turned counterclockwise, the hour hand will turn clockwise for one hour. When the name of the representative city in the destination time zone is changed to 12 o’clock, the adjustment is completed. In this process, the world time mechanism and hour hand are separated from the movement, so the balance swing and the rotation of the minute hand are not affected. The chronograph hands will not show any abnormalities and continue to operate normally.
Complex machinery, elegant charm
Ref. 5930 combines a chronograph with a world time watch in a round case in 18K white gold. Its small wing-shaped lugs are its feature, and it is also an iconic element of the World Time Watch in the 1940s and 1950s. The time zone adjustment button is at 10 o’clock and is rectangular like the two timekeeping buttons. This shape is common on Patek Philippe’s classic chronographs. Through the sapphire crystal caseback at the bottom of the case, you can admire the beautiful design and delicate details of the movement. The centerpiece of the auto dial is decorated with a delicate rotating circle pattern, while the eccentric rotor is decorated with round grain and is engraved with the Calatrava cross pattern. The silver shiny rhodium-plated splint is also decorated with round grain. All of these parts have polished chamfers, polished grooves, and gold-embossed engravings that do not meet Patek Philippe’s requirements. They set off the beautiful colors of the ruby bearings, the gold color of the Gyromax® balance, and the violet and blue rays of the patented Spiromax® balance spring made of the revolutionary silicon material Silinvar®. The end of the Spiromax® balance spring is specially designed by Patek Philippe, which retains the stability of the Breguet hairspring and shapes the slim shape of the flat-roll hairspring.
All functions at a glance
The dial of the Ref. 5930 gives you a glimpse of how two complex functions fit together perfectly. The outermost blue discs list the names of 24 cities in each time zone. Representative cities in some time zones have been updated. For example, Riyadh has been replaced by Dubai and Noumea has been replaced by Brisbane. In addition, because the Moscow time zone has been changed from UTC + 4 to UTC + 3, corresponding changes have also been made on the city disc. The seconds scale of the chronograph function is located between the city disc and the 24-hour scale ring, which is a narrow white round scale ring that is accurate to a quarter of a second. This indicates that the corresponding vibration frequency of the movement is 4 Hz (28,800 A / h). The 24-hour dial ring turned counterclockwise can also be used as a day / night display. The dark areas that represent night are paired with bright numbers and are marked with the moon; the bright areas that represent day are colored with dark numbers and are marked with the sun. The design of the center of the dial follows the tradition of the World Time series: except for the 18K white gold hour markers and the 30-minute cumulative timer, all are decorated with delicate hand-carved patterns in a low-key manner. The dial of the 30-minute cumulative chronograph has a striking white gold frame, white minute markers, and elegant round grain details. This design is not only for aesthetics, but also to ensure the clarity of the dial layout.
The Patek Philippe World Time Chronograph Ref. 5930 was officially launched in 2016. This time the watch is released in a white gold case with a blue hand-engraved dial. The strap is hand-stitched in matte navy blue square scale crocodile leather to match the dial color. The 18K white gold Calatrava folding clasp ensures that the watch comfortably and securely surrounds the wrist.
