What are the specific explanations of the functions of tourbillon, minute question and perpetual calendar in high-end watches?

Tourbillon and perpetual calendar are called the three most complicated functions in mechanical watches.

Tourbillon

Tourbillon is neither a tuo nor a wheel. Its name comes from the French word "tourbillon", which means "whirlpool". Specifically, it is a "clock speed regulating device", which was invented by Swiss watchmaker Louis Breguet on 1795. This is also one of the irreplaceable factors of Breguet watches in the history of watchmaking culture. The original intention of the invention is to counteract the error caused by the gravity on the components in the watch escapement system.

perpetual calendar

A perpetual calendar watch does not mean that it can really run for 10 thousand years, and there is no error at all. In fact, it needs to be adjusted once every 100 years. Some people think that the perpetual calendar is the simplest of the three complicated functions, so why is it so expensive? Think about it. In an ordinary weekly calendar, you have to manually adjust the date when you encounter a big month or a small month, otherwise you will encounter an embarrassing scene that it is clearly May 1, but the watch still displays April 3 1.

Minute repeater

Minute repeater, also known as triple reed watch, can distinguish the time of "hour", "engraving" and "minute" with three different reed sounds, which is the result of the application of acoustics and dynamics. It was originally designed to let people know the time according to the sound type and time of the watch without looking at the watch in the dark. Generally speaking, bass reports hours, treble reports moments and treble reports minutes.

principle of operation

The manufacture and production of watches are based on a simple and witty invention, that is, "clockwork". It can tighten and store energy, and it can slowly release energy to push the running device and hands in the watch to display time. This spring device in the watch is called the mainspring.

Watch structure A watch consists of a meter head and a strap (clasp). Among them, the parts of the rice head include: movement, case, bottom cover, mirror, characters (often called dial), hands, handles (also called push) and order (required by some tables).
