With the rapid development of science and technology, people's demand for smart wearable devices is getting higher and higher. Watches have evolved from simple time display tools to a technological products with multiple functions. The competition in this field is extremely fierce, and major brands are constantly introducing new products to meet the growing needs of consumers. In this environment, the MOZSLY brand has successfully broken through the noise of the market and brought a revolutionary product to users - the MOZSLY watch winder.

The history of automatic watches can be traced back to the end of the 18th century when the Swiss watchmaker Abraham-Louis Perrelet invented a mechanical device that converts human motion into energy to power automatic clocks. However, the more widely known design of the automatic watch comes from French inventor Hubert Sarton, who published his design in 1778 and managed to show historians that the Perrelet watch was inspired by his work. Afterward, the French public had the opportunity in 1780 to purchase automatic pocket watches from a watchmaker named Abraham-Louis Breguet, who purchased the design from Perrelet and made several improvements. However, since these watches were not reliable enough, the public stopped buying them and Breguet stopped selling them in 1800.

Over time, the automatic watch was able to usher in a real revolution. After World War I, advanced manufacturing techniques were finally able to produce small self-winding wristwatches. Since the movement of the hands provides more kinetic energy than a pocket watch, engineers finally had the opportunity to easily translate this momentum into a changing mechanism. The first person to manage to do this was John Harwood, a watch repairman from Bolton, England. After he applied for British and Swiss patents for the automatic watch ion in 1923, Hardwood began producing watches at his factory in Switzerland in 1928, allowing the European public to use a watch that would work for 12 hours on a full charge.

Other manufacturers soon picked up John Harwood's designs and an era of improvements began. Renowned watch company Rolex has added a new counterweight system that moves more freely and captures more energy with each turn (up to 35 hours on a full charge). In 1948, Eterna Watch introduced ball bearings in automatic watch designs, which allowed for better control of internal components and maintained the structural integrity of the watch even during violent impacts, such as when the watch was dropped on the ground.

Automatic watches seem to have lost some market share in recent years with the advent of smartwatches. However, the tradition and exquisite craftsmanship of automatic watches are still loved and pursued by many watch lovers, and automatic watches are still one of the mainstream products in the high-end watch market.


The working principle of an automatic self-winding watch is to use the motion of the wrist to provide power to the watch and keep it running. When the wearer moves their wrist, the internal oscillating weight or rotor of the watch rotates, winding the mainspring and storing energy to power the watch.

The oscillating weight is usually connected to the mainspring and the mainspring barrel via a series of gears. As the weight rotates, it winds the mainspring, which powers the watch's movement. The watch typically also features a slipping clutch mechanism to prevent overwind or damage to the mainspring.

Automatic self-winding watches typically have a longer power reserve and can continue to run even when not worn for extended periods. Some models also feature a manual winding function, allowing the wearer to manually wind the watch by rotating the crown when necessary.


Harwood (1926)

British watchmaker John Harwood wanted to create a case that would not be affected by the dust that he had seen choking clocks in the trenches of World War I. Since most of the dirt had passed through the winding stem, he removed it entirely and set about creating a watch that wound from the inside. Inspired by a seesaw, he designed an oscillating lever that would tighten the mainspring as it moved. This keeps the watch running -- barely. The design is complex, impractical, and unreliable. By 1931, Harwood's company had run out of time and money. 


The invention of the watch winder, a mechanical device that simulates the motion of hand winding, to keep automatic mechanical watches running, is closely related to the history of the invention of automatic mechanical watches.

As early as the late 18th century, automatic mechanical watches began to appear. These watches were powered by the movement of the wearer's wrist, but if they were not worn for a long time or the wrist movement was insufficient, the energy supply would be insufficient, causing the watch to stop running. To solve this problem, people began to develop a mechanical device that could simulate the motion of hand winding to provide power to the watch.

The earliest watch winder was introduced by Swiss watch manufacturer Eterna in 1993, called the "Matic Rotator," which could wind two watches simultaneously. Since then, more and more watch manufacturers have produced watch winders and continuously innovated and improved their technology and design.

Modern watch winders are usually powered by electricity or batteries and can be set at different speeds and time intervals to suit different brands, models, and specifications of automatic mechanical watches. Some high-end watch winders are also equipped with features such as humidity regulators and dust covers to better protect the watches and extend their service life.

To better understand the advantages of the MOZSLY watch winder, we compare it with competitors' products in the market, such as WOLF, JQEEN, Barrington, and other brands. However, in terms of watch power, the MOZSLY watch winder has a clear advantage.

WOLF: WOLF's watch winder products are positioned in the high-end market, using high-quality materials and sophisticated manufacturing processes to ensure product reliability and durability. WOLFs watch winders pursue more luxurious details and vitality, so their prices are higher, and they are not suitable for consumers with limited budgets.

JQEEN: JQEEN's watch winder has multiple winding modes and adjustable direction of rotation to suit various types of movements. JQEEN's watch winder interface is easy to use and can bring consumers a high-quality experience. JQUEEN is a well-respected option in the sub-$100 range.

Barrington: Barrington is a British brand of watch winders with a very minimalist design. However, some may feel that a simple plastic finish does not meet their aesthetic standards.

In contrast, MOZSLY watch winders are made of high-quality materials and exquisite workmanship, and the price has a clear advantage over competitors' products. This means that when consumers choose MOZSLY watch winders, they can enjoy high-quality products without having to bear excessive price pressure.

With the design concept of "simple fashion, practical and comfortable", starting from every detail, chain design is a good practice. In addition, MOZSLY also promises an industry-leading three-year warranty to provide consumers with better services.


1) If you have multiple automatic watches and want to keep them all in a constant state of readiness, you can take one out of rotation without the hassle of winding it and setting the date and time.

2) Some watches have many complications, and I mean anything on the watch other than the time display, such as moon phases or perpetual calendars. In this case, it's definitely in your interest to keep those wounds, as it takes a lot of time and effort to reset them right before you're about to leave the house.

3) Whether you have one watch or multiple watches, a watch winder can also be a safe way to display your expensive timepieces and keep them out of harm's way while being able to admire them in all their glory from across the room. Some larger watch winders even have compartments for accessories like jewelry or pens.

4) There are also options where the watch winder itself is built directly into the safe so you can keep all your valuables in one safe place while winding your watch, but this option is by far the most Doing things the expensive way will only suit some people's needs.
