Patek Philippe Alarm Travel Time reference. 5520P

Patek Philippe Travel Time Ref. 5524G, the brand decided to dive into complication through the Travel Time model, and launched a complication at Baselworld 2019, which adds a 24-hour alarm mechanism and displays the set alarm on the dual aperture The time is digitally. The alarm signal is struck by a hammer on a classic gong. To make this possible, Patek Philippe has developed a new integrated movement and applied for four patents for its alarm mechanism. New Patek Philippe alarm travel time reference. 5520P is the result of five years of research and development.

When Patek Philippe engineers were asked to develop a new alarm clock mechanism and combine it with the two time zone arrangements of the Travel Time concept, one goal was to make the watch as thin as possible. Therefore, they chose an integrated movement, which is smaller in height than a movement with additional modules, but it is also more difficult to design and produce. They also hope that this new complex function is easy to operate, functions intuitively and prevents error handling.

New Patek Philippe cheap alarm travel time reference. The 5520P has a platinum case with a diameter of 42.2 mm and a thickness of 11.6 mm. This is the first time that a Patek Philippe watch is equipped with a waterproof case. For this special model, its waterproof depth has been set to 30 meters. New reference. The 5520P has a classic gong. When the alarm is triggered, the hammer (visible through the back of the display) will strike the gong for 40 seconds at a frequency of 2.5 strikes per second-a total of 90 strikes. The alarm device has its own independent barrel, which is wound at 4 o’clock. The built-in clutch prevents accidental winding. In addition, since the watch is waterproof, the gong is directly connected to the strap instead of the usual movement to reduce the attenuation of sound waves by the waterproof box.

The button at 2 o’clock turns the alarm on or off. If the alarm is turned on, the small bell-shaped hole just below 12 o’clock is displayed in white, and if the alarm is turned off, it is displayed in black. The corresponding button is engraved with a small bell symbol whose shape is the same as the shape of the alarm ON/OFF indicator hole. The push rod has the same interlocking device as the two time zone push rods.

With a matte ebony black sunburst dial-the sunburst effect is difficult to appreciate in metal-the alarm function indicator is located on the upper part of the dial. The programmed alarm time is displayed in the double hole below the 12 o’clock position, and directly below it is a circular hole. The white of the day/night indicator is displayed from 6 am to 6 pm, and the blue is displayed from 6 pm to 6 pm. The time at 6 am is displayed. . There is a bell-shaped hole above the double hole to indicate whether the alarm is on or off.

The crown at 4 o’clock must be pulled out to the middle position to adjust the alarm time by turning it for 15 minutes in either direction. The alarm time display mechanism in hours and minutes drives the differential. The gear constantly compares the preset alarm time with the current local time. The system that counteracts the mechanical gap can set the alarm sound as accurate as one minute to the next quarter of an hour. For example, at 12:14, the alarm can be set to 12:15. The mechanism has been patented.

With its technical charm and elegance, the dial ensures the best readability and highlights its origin in the field of pilot watches. Arabic numerals and broad baton pointers applied on a large area-all in white gold, with a white Superluminova coating, both beautiful and bright. There is a small dial at 6 o’clock, indicating the date from 1 to 31.

The new internal self-winding movement AL 30-660 S C FUS consists of 574 parts and 52 jewels. When fully wound, the movement beats at a frequency of 28,800 vph and provides a 52-hour power reserve. The movement has a system to prevent damage to the movement caused by misoperation. After the alarm stops sounding, the ON/OFF indicator will automatically switch to OFF. Now, the alarm cannot be set again until the bouncing spring barrel is completely rewinded. Therefore, the alarm mechanism must always be able to sample the state of the wind of the spring. The power reserve can be released ON state only after it is fully tightened. However, it can be switched to the OFF state at any time. Even if the alarm goes off, users can transition to another time zone without danger. In this case, the mechanism only interrupts the strike sequence and sets the alarm to OFF. When a new alarm time is set, the alarm alarm will also be disabled.

Even though the movement can be seen through the case back, Patek Philippe provides a replaceable sturdy case back for those who wish to completely cover the movement.

On the wrist, the new Patek Philippe alarm travel time reference number. The 5520P wears very beautifully and fits its size perfectly. The watch has a black calfskin strap (similar to the nubuck leather that Patek Philippe has never used before) with a Clevis fork buckle. Together with the 5524G and 5524R, this is yet another of Pilot’s outstanding watches that can meet all needs. Beautiful and amazing complications are indispensable for those who seek Patek Philippe’s sports complications.
