Masterpiece Of Girard Perregaux 1966 Series Three-question Calendar Astronomical Time Difference Watch

Girard-Perregaux 1966 series of three-question almanac astronomical time difference watch, which integrates the functions of three major timepieces, the 42 mm diameter case has ample space, the movement consists of more than 400 parts, the dial three The large function layout is well balanced, making it a masterpiece of timepieces.

 Girard-Perregaux 1966 series is elegant and authentic. The dial design exudes a harmonious aesthetic. The seemingly simple appearance conceals extremely complex mechanical structures. The technical innovations in this one deserve to be tasted, showing the top watchmaking craftsmanship of Girard Perregaux techinque level.

 The scale of the dial is just right. The silver-plated sun ray texture modification and sharp solid gold hour markers support the operation of the hour and minute hands and a large number of displays: the date display at 1:30, and the month display at 7 o’clock on the opposite side to form the calendar system As long as the crown is adjusted once a year in February every year, the rest of the year is correct.

 The 4:30 position of the dial is an astronomical time difference display. This function is driven by a cam that rotates once a year, showing the difference between the clock time (real time) and the real solar time (real time). There is a slight difference from the real solar time, only four times a year are completely the same. The range of the remaining days is about +/- 15 minutes, and the difference in November is up to 16 minutes.

 In the era when the minute repeater function was available, there was no power supply. To know the time in the dark environment at night, the minute repeater can tell the hour, hour and minute. From today to today, the minute repeater is the best watch connoisseur. Appreciate one of the complications. The fine adjustment of the timekeeping system is very precise. Only experienced watchmakers can control it with clever hands and ears, making the timekeeping sound more crisp and pleasant. Girard Perregaux’s timekeeping system is the result of careful sound technology research and development. In particular, the three elements of the case structure are the key to improve the quality of the timekeeping sound. One is that the inside diameter of the case perfectly matches the size of the movement. Provide the most ideal resonance effect; the second is that the micro-curved case back can increase the amount of air between the movement and the case to produce a better sound, and the third is that the inside of the case back is polished by diamonds to reduce acoustic interference.

 Crystal glass case back perspective exquisite craftsmanship of manual winding movement: the shape of the semi-arrow-shaped balance wheel plywood is reminiscent of Girard Perregaux’s most representative golden bridge plywood design, showing the excellent craftsmanship tradition and aesthetics Tactile.
