Watches with calendars are so common now that they are very convenient to use in life. When you fill in the date, you don't have to ask someone else today, you don't have to look at the phone, you can lift your hand. Ordinary calendar watches have a small "defect" - you need to manually adjust the date in the small month, the date will be accurate.
The watch has a magical date display function, which can automatically distinguish between big and small months, and even the four-year leap year can't beat it. Numerous rich tycoons have spent a lot of money to play watches with this function only for collections. It is the perpetual calendar function of one of the three complex functions of the watch. The perpetual calendar watch can really be as the name suggests, that is, can it be adjusted once in a million years? If this is the case, then it is really "love you for ten thousand years"!
A perpetual calendar watch is not a watch that can display a date of 10,000 years. The English name of the perpetual calendar watch is Perpetual Calendar, which is intended to be an eternal calendar. It recognizes the current month and knows the current year and even knows if this year is a leap year. It will automatically embed the 29th day in February of the following year. Therefore, as long as the watch is running well, the only time to adjust the date is at the end of February, which is not the leap year of every 100 years. For example, it needs to be debugged in 2100.
The perpetual calendar movement can be divided into two parts, one part is the timekeeping of the hour, minute and second, and the other part is like a set of astronomical self-propelled mode. It operates with a miniature satellite gear system and the whole system rotates once a week. It takes four years. The leap year calculation can be described as the secret of the perpetual calendar watch. In the watch, the perpetual calendar function is realized by a set of independent components. The perpetual calendar can theoretically be matched with different movements.
The "master brain" of the perpetual calendar is the 48-month gear, which is detailed data for 48 months. The calendar component reads the data of the 48-month gear scale groove to correct the calendar display. The 48-month gear has been measured and designed with different depressions, indicating the number of days per month, that is, “calculating†whether it is 28 days next month, or 29, 30 days or 31 days. In this way, the perpetual calendar watch with this system can accurately display the current date and month.
Next, we will introduce a Chinese-style perpetual calendar watch, the Blancpain Chinese calendar watch. The elements of this watch's traditional Chinese calendar, such as the 12 o'clock, the lunar date, the month (in combination with the display of the moon), even the five elements and ten days. The Zodiac corresponds to the twelve earthly branches, and matches with ten days to form sixty basic units or sixty thousand branches, commonly known as "sixty-eight", which constitutes the core content of Chinese traditional culture.
The Chinese calendar watch has a fine layout, with hour, minute hands and calendar hands on the disk. It is equipped with a new 3638 self-winding movement with power reserve of up to seven days. The movement has a diameter of 32 mm and a thickness of 8.3 mm. Both sides of the splint and the bridge are finely ground. In particular, the bridge on one side of the disc is almost hollowed out. The watch is made of red gold and has a case diameter of 45 mm and a thickness of 15 mm. The crown is decorated with a round cut ruby. Under the lugs, the patented hidden adjustment button is designed to quickly adjust the functions.
The function of the perpetual calendar watch is really cool, but the price is also very expensive. The price of our common calendar watches is affordable for most people. It is not too much trouble to manually debug the date in the small month. It is also a good choice.
