Watch with tourbillon
Tourbillon in hours what is it?
Tourbillon [fr. tourbillon- cycle] - a mechanism in a mechanical clock that turns the mechanism of a clock to compensate for the effects of gravity. Using this solution allows you to achieve the accuracy of mechanical watches up to +/- 1s / day, which is a very high figure among the watches of this class.
Tourbillon is a rather complicated and expensive mechanism, and its effectiveness has been repeatedly challenged by many watchmakers.
With the advent of mechanical watches, many European masters worked to improve the accuracy of chronometers. Improving the quality of machining the parts of clockwork mechanisms, using gems as friction bearings, made it possible to achieve a sufficiently high accuracy of the watch movement. However, there were several factors that influenced the accuracy of the course and could not be compensated, only by improving the quality of the machining and assembly mechanism. This is the temperature change of the geometry of the parts of the mechanism and the effect of gravity. And if the first problem was solved by using alloyed hardened steels in the watch, the second problem remained relevant until the beginning of the 19th century. So far in 1801, the French watchmaker Louis Brigget did not patent his invention - Tourbillon. This mechanism consisted of an anchor fork, a small moving frame and balance. He turned the main mechanism of the clock around its axis for a minute, thereby compensating for the effect of gravity. This invention made it possible to achieve an unprecedented, at that time, accuracy. Over time, many Swiss watch manufacturers began using various variations of the tourbillon in their watches. At the moment, similar models are in the collections of Breguet, Audemars Piguet, Patek Philippe, Hublot, Franck Muller, Vacheron Constantin and others.
The principle of the tourbillon.
The basis of any mechanical mechanism of the watch is a wound spring, which with the help of an anchor fork converts potential energy into kinetic energy of balance oscillation. The balance oscillates with a certain frequency of half-oscillations per hour. Frequently, the frequency ranges from 21,600 to 28,800 vibrations per hour. With a fixed balance position, it is affected by gravity, which is similar to the Foucault pendulum, affects the amplitude of oscillations and reduces the accuracy of the clock. The tourbillon rotates the watch mechanism together with the balance by changing the axis of oscillation of the balance relative to the earth plane, as a result of which the earth gravity uniformly affects the amplitude of oscillations. Usually the tourbillon turns the mechanism of the clock for one minute, forcing the clock to half a minute to hurry, then half a minute to be late.
Buy a watch with a tourbillon
Tourbillon is a rather complicated and expensive invention. Its use in watches is primarily due to the need to show the skill level of a watchmaker and the high status of watch owners. Watches with this invention are made either skeletonized or at least with a window through which the work of this mechanism can be seen. Often the price of even the cheapest tourbillon watches starts from $ 1000. Copies of Swiss watches based on Chinese movements Seagull TY80XX (ST80) are also widely used. Despite the Asian mechanism, such models show very high accuracy and reliability. You should also not confuse the visible pendulum or dummy with a real tourbillon. In some cheap models, a visible balance is given for a tourbillon. You can buy a watch with a tourbillon in the store Lux33. This section presents a watch with a really high-precision tourbillon.
