Glamorous Brief Comment On Girard Perregaux 1966 Series Time Equation Watch

Girard Perregaux 1966 series has added an annual calendar astronomical time difference watch to SIHH in Geneva 2012. Not only does the appearance inherit the consistent elegance of Girard-Perregaux 1966 series, but the ruthenium metal dial and time equation Functional responsibility highlights the uniqueness of this watch. Today, the Watch House brings you a brief review of Girard Perregaux 1966 series time equation watches. The official model of the watch is: 49538-52-131-BK6A.

 The time equation, also called ‘astronomical time difference’, is a fever-level function in the field of watchmaking technology. To enhance the technical value of this new model, Girard Perregaux is equipped with the newly developed Microvar cardless balance spring in the movement. The wheel frame is equipped with 6 correction screws and 2 weights, which can be independently adjusted. Improve the quality of swing and frequency, so as to improve the accuracy of the display of the almanac and astronomical time difference, and the movement of the movement from the sapphire crystal case back to see.


The watch’s functional layout is new, it can be said that it is a masterpiece of the combination of top-level timepiece function and elegant style. The watch is crafted in an 18K rose gold case with a 40 mm diameter design.


The so-called true solar time (also known as apparent solar day, true solar day, etc.) refers to the time interval between the real sun passing through the meridian of the place twice. But because the earth is in an elliptical orbit, its speed of movement and its distance from the sun are constantly changing, so the time of each true solar day is not the same.


The watch comes with a black alligator leather strap, which is soft and comfortable. The buckle adopts a pin buckle design made of 18K rose gold, which is simple and safe to wear.


The rose gold case has a diameter of 40 mm, a thickness of 10.72 mm, and a water resistance of 30 meters. It is only suitable for daily waterproofing. This thickness is also very comfortable to wear on the wrist.

The mean solar day is the average of all true solar days in a whole year, and is also called the mean solar time. 1/86400 of a flat solar day = 1 flat solar second (24 × 60 × 60 = 86400 seconds in a day) as the basic unit of measuring time. Modern clocks are designed and manufactured according to this principle. Because this watch does not have sunrise and sunset time display, there is no need to design and manufacture according to the longitude and latitude of the user’s area.
