The movement is as important to the watch as the heart is to the human body. The heart sends blood to the whole body by beating continuously to maintain the daily functions of the human body. The movement of the automatic watch is mechanically converted and stored by the potential energy of the oscillating weight, providing a continuous power for the automatic watch. Compared with manual winding timepieces, a major feature of automatic winding watches is that there are different types of rotors on the movement. Their presence makes it easier and more convenient for the watch to obtain power, eliminating the need to take it off. Trouble winding the watch. As long as it is worn between the wrists, energy can be obtained by a slight swing of the arm, which is very convenient. It can be seen that the importance of the oscillating weight for automatic movements and even watches is extraordinary. Over the years, major brands have also racked their brains to work on the oscillating weight, constantly expanding the charm of the oscillating weight on watches, attracting watch lovers. Can’t help but love the ‘big guy’ on this movement.
From ‘chicken ribs’ to the indispensable ‘lazy design’
Back in the days when pocket watches became popular, the oscillating weight had been used on clocks. In the 18th century, the first chronograph device with a oscillating weight was successfully designed by Swiss talented watchmaker Abraham-Louis Perrelet. As long as the watch maintains physical movement, the similar in this device The design of the pendulum will power the mainspring. This device has also become a milestone in the history of watches and clocks, and it is the world’s first self-winding structure.

But in the era of pocket watches, this design was unpopular, because pocket watches were mostly kept in pockets, and clocks were pulled out of them only when needed to check the time. Such short movements are obviously not enough to allow the pendulum to be used for timepieces. The energy required to travel, so this watch creation was put on hold by the times. Fortunately, in the early twentieth century when the watchmaking era changed, the watch replaced the pocket watch as an emerging category, and this invention was rediscovered. In 1923, a British watchmaker named John Harwood developed an automatic watch, which placed a heavy weight on the axis of the movement, and obtained potential energy with the movement of the wrist. Swipe brings new impetus to the mainspring.

Since then, the development of the pendulum has been valued by more and more watchmakers. With its lightweight and convenient characteristics, it has become an indispensable design on watches. Nowadays, automatic mechanical watches are common. When you inadvertently stretch or run, the oscillating weight quietly moves with the rhythm and contains the energy of the watch.
Conventional traditional semicircular rotor

Nowadays, the more common traditional oscillating weight is usually a semi-circular design, and some brands have also beautified it through hollowing out, polishing, and chamfering to make it highly ornamental. Generally, the oscillating weight will ‘occupy’ half of the movement’s field of vision, so some brands will place its LOGO, movement data and exquisite decoration in it, on the basis of enhancing the added value, it will show the movement’s inherent strength and charm . Such as the anchor design of the Athenian brand, Glashütte’s original homemade movement.
Classic hits that have appeared before
The striker inspired by the seesaw is based on iron feet at both ends, which generates a limited circular movement with gravity to promote its charging of the watch. Today’s famous watch brands Omega and Audemars Piguet have used it (you can see it on some antique watches). Through the enhanced version of the striker (adding spring), the strength of the pendulum against the splint can be cushioned and increased The service life. However, due to poor winding efficiency and other reasons, it died in development. Active in the middle of the 20th century, it could not keep up with the times, so he can hardly be seen on today’s watches. However, as an integral part of the history of watches and clocks, its appearance has also promoted the development of automatic watches, and it is also one of the more interesting structures on mechanical timepieces.
Beautiful and delicate pearl
With the progress of the times, people’s demand for slim timepieces is increasing (because of the ability to load complex functions), so the ‘weight loss project’ of the movement is urgent. At this time, the wise watch designers once again set their sights on the ‘big’ pendulum on this movement, narrowed it down into the splint, and formed a delicate and beautiful mini-rotor. Born in the 1940s and 1950s, it not only has a simple and elegant appearance, but also contributed to the slim timepiece movement, so this outstanding feature can still be seen in most slim timepieces. the design of. Compared with the traditional Tuo, this ‘little guy’ is only in a corner, integrated with the other parts of the movement, complement each other, and highlights the beauty of the whole movement.
I once wrote the relevant information about a mobile watch of the Bucherer Maliron series. Like the table friends who first contacted this brand movement, I felt that there was no trace of the oscillating weight on the surface of the movement. Mystery. It turned out that the patented design of this outstanding brand reduced the huge oscillating weight to a black curved ‘curve’ again, sliding along the edge of the movement with gravity to power the watch. It does not cover the appearance of the movement at all, it shows the brand’s unique wisdom and extraordinary skills.
Kunlun Golden Bridge Series Vertical Rotor
The vertical automatic tourbillon belongs to the unique design of the famous Swiss brand Kunlun watch Golden Bridge series. It was first introduced in 1980. With its unique impact and freshness, it has become a unique timepiece in the hearts of many watch friends. A new chapter. Launched in 2011, this timepiece is the first wristwatch with linear windings to provide energy for the timepiece’s movement by generating power as the wrist moves up and down. This design is also one of the more novel among the many pendulums, presenting the essence of timepieces in a completely different way. Because the trend and design determine the dense characteristics of the air section on both sides of the watch, which is also a major design of the brand.

Summary: Through the transparent back cover of sapphire glass, the appearance of the movement will appear in front of you, and the most conspicuous design is the rotor, which not only provides dynamic support for the clock, but also adds charm to the charm of the back cover. Designing different oscillating weights will have a completely different watch-watching experience, making people fall in love with the beauty of this micro-machine on the wrist.
