Ref. 5235 3-needle and 1-line annual calendar watch (Annual Calendar Regulator) published by Patek Philippe, Switzerland’s top watch brand, is not only the first modern Patek Philippe to use a 3-needle-line (regulator) dial The design style, Patek Philippe has developed a new 31-260REG QA automatic movement especially for this outstanding style. The 31-260 REG QA caliber is Patek Philippe’s first ultra-thin self-winding caliber equipped with a mini-automatic oscillating weight and a small second at six o’clock. It is also equipped with a Pulsomax escapement made of Silinvar silicon and The Spiromax balance spring, which combines Patek Philippe’s proud Geneva watchmaking tradition and innovative elements, marks a new chapter in Patek Philippe’s brilliant legend.
Three stitches, one line The grandeur of the King of Precision: Patek Philippe Ref. 5235
Hours, minutes, and seconds use a three-handed, one-line, so-called correction clock / regulator design. It has a long history. In the office of Philippe Stern, Honorary President of Patek Philippe, there is an accurate correction clock made at the beginning of the last century. Every second, without interruption. The Ref. 5235 released by Patek Philippe in June 2011 is the brand’s first watch with a three-pin and one-line design. It is equipped with a large clear faceplate and a new 31-260 REG QA automatic movement that is more accurate than the previous generation. , Fully demonstrate the precise and clear style of the king of Patek Philippe.
Patek Philippe 5235 three-pin first-line calendar watch, 18K white gold case
For more than 200 years, precision pendulum clocks have been an essential tool for all watchmaking studios and observatories to record standard time. These pendulum clocks use the large disc on the surface to indicate the minute scale, the small disc at the top to indicate the hour mark, and the small disc at the bottom to indicate the second. When adjusting the timepiece, you must be able to see the movement of the second hand on the pendulum clock, and your sight must not be obstructed. The design of the three-needle, one-line correction clock has the meaning of ‘accurate timing, clear and reliable display’, which is completely consistent with Patek Philippe’s watchmaking philosophy, which led to the birth of a new style 5235 three-needle and one-line calendar watch.
Inspired by a precision-calibrated clock from the beginning of the last century in the office of Honorary President Philippe Stern
The faceplate design of the 5235 three-pin first-line calendar watch is the first of its kind. In addition to the hours, minutes and seconds, the three-hand first-line is listed above and below the dial, and the ten, two and six o’clock directions display the day, month and date in windows. The time, track-type minute scale and hands are in blue tones, set against a silver-gray two-tone faceplate, which is clear and unobtrusive when displayed. The brand chooses its most classic Calatrava to present this brand new timepiece. The 40.5 mm diameter case consists of the bezel, the case and the bottom cover. The shape is round and beautiful, which is called the Bauhaus “function depends on shape” design philosophy. Great example. The bezel is carefully chamfered, the body of the watch is decorated with a straight pattern, and the surface of the lugs is slightly inclined. The chamfer of the bezel is extended to make the overall line more perfect and more comfortable to wear.
Thanks to the newly designed 31-260 REG QA ultra-thin self-winding movement, which is only 5.08 mm thick, the 5235 three-pin first-line calendar watch with annual calendar function is only 11 mm thick, which is amazing. Through the sapphire crystal back cover, you can see this exquisite movement with Patek Philippe imprint: including the beautiful machine and splint composition as shown in the picture, the Pulsomax escapement made of silicon, the Spiromax balance spring, 22K gold The Geneva rotating circular pattern on the mini-rotor, the Geneva stripe pattern on the bevel, and various gold carvings.

Patek Philippe 31-260 REG QA ultra-thin self-winding movement
The 240 ultra-thin self-winding movement of Patek Philippe, introduced in 1977, is equipped with a 22K gold miniature automatic winding oscillating weight, which is embedded in the main board. The thickness of the movement is only 2.53 mm, which is still the thinnest automatic in the watch industry. One of the winding movements. Unfortunately, the movement 240 is only 27.5 millimeters in diameter, and the small second hand shows the eccentric 5 o’clock position, which is not suitable for the Ref. 5235 calendar with a three-hand and one-line dial configuration. Patek Philippe decided to stand on the great foundation of the 240 movement and develop a new generation movement with the traditional advantages of the 240 movement, but with contemporary vision and innovative features.
Like the 240 movement, the 31-260 REG QA automatic movement with a micro-shaped automatic winding top design is only 5.08 mm thick (the basic movement diameter is 31.74 mm and the thickness is 2.60 mm). In terms of size, it is in line with Patek Philippe’s recent years. The need for a small increase in the size of the watch, with a diameter of 33 mm, is not only more suitable for the large case size of Ref. 5235 with a diameter of 40.5 mm, but also the small second hand at 6 o’clock is more independent and clear. effect. What’s more notable is that the 31-260 REG QA automatic winding movement has four innovative technologies, which are technically enough to lead another period of popularity for decades.
31-260 REG QA self-winding movement, only 5.08 mm thick
Patek Philippe 31-260 REG QA automatic movement has four major innovations
1.Pulsoma x Silinvar silicon escapement and Spiromax balance spring
It is one of the great achievements of Swiss watchmaking industry to make escapements and balance springs made of silicon material with antimagnetic and abrasion resistance. Patek Philippe is one of the leading manufacturers leading this trend. Since 2006, Patek Philippe Advanced Research has launched four limited edition models with silicon escapement and / or silicon balance spring, including 5250, P5350P, 5450P and 5550P, equipped with 31-260 REG QA The Ref. 5235 three-pin first-line calendar of the movement is the first non-limiting conventional style fully equipped with the Spiromax balance spring made of Silinvar silicon and the Pulsomax escapement (escape fork and escape wheel). Spiromax balance spring with patented ‘patek Philippe end arc’ geometric design, can be retracted in absolute concentric state, excellent isochronism; plus the power efficiency is also improved by the Pulsomax escapement, the timing is more accurate .
2.New travel gear and gear
Patek Philippe has completely transformed the time train, balance wheel and pinion between the main barrel and the escapement wheel. The tooth shape and pinion blades have been redesigned to improve their meshing, reduce friction and increase the tolerance range of different wheelbases, thereby improving the efficiency of energy transmission between the barrel and the escape wheel.
The 31-260 REG QA movement has been redesigned to further reduce frictional resistance
3.The vibration frequency of the movement is increased to 23,040 times / hour
The frequency of the Patek Philippe Classic 240 movement is 21,600 times per hour, and the frequency of the 31-260 REG QA movement is increased by 10% to 23,040 times per hour. ”Higher standard, reaching a daily error of -3 / + 2 seconds.

4. Extra long springs provide 60 hours of power storage
Although the single barrel design is the same as the 240 movement, and the frequency of the movement is higher, the power storage of the new 31-260 REG QA movement has been increased to 60 hours (48 hours for the 240 movement), which is mainly Thanks to the use of a more flexible and longer mainspring, the efficiency and friction of gear sets and escapements are also one of the reasons. In this way, even if you do not wear a watch on the weekend, you do not need to worry about the stop of the watch on Monday and you must recalibrate the time and calendar display.
