What Is An Automatic Watch?
An automatic watch is a mechanical timepiece that winds itself using the motion of the wearer’s wrist. It does this by means of a rotor: a semicircular weight that spins with movement which winds the mainspring and powers the watch. Unlike quartz watches, automatic watches do not require a battery. However, while they are powered by wrist movement, they may still need occasional manual winding especially after stopping or if not worn regularly.
There is a fundamental difference between automatic watches and other watches, such as quartz or manual watches. Quartz watches rely on electronic circuits and are battery-powered while manual watches like automatic watches also use mechanical movements but require the wearer to wind the crown regularly. The automatic watch is self-winding and as such, more practical.
The first self-winding mechanism appeared in the late 18th century; this invention was contested between Abraham-Louis Perrelet and Hubert Sarton. Over time, new brands like Seiko and Rolex have refined the technology. Today, modern and more affordable innovators like SÖNER Watches, a rectangular watch brand, continues the legacy by blending Swedish design with premium materials and movements.
How Does An Automatic Watch Work?
All automatic watches are mechanical watches but not all mechanical watches are automatic watches. Automatic watches operate using a mechanical movement powered by motion. Wrist movement spins the rotor. This winds the mainspring, which stores and releases energy to power the watch.
The rotor spins freely on a pivot. As it rotates, it winds the mainspring, thereby converting motion into energy. This energy drives the gear train, which is responsible for hand movements and the date and moon phase. The escapement ensures that energy is released in controlled intervals while maintaining accurate timekeeping.
This process is purely mechanical as no electronics or batteries are involved. The watch will continue working as long as it is worn regularly or manually wound when not in use. The conversion of motion into timekeeping is what makes automatic watches both functional and fascinating.
What Is The Working Principle Of Automatic Watches?
At the heart of the clever mechanical system that transforms motion into timekeeping is the rotor. The rotor is a semicircular, weighted disc that spins freely with the movement of the wearer’s wrist. As it rotates, it winds the mainspring, a coiled spring that stores energy. The stored energy is gradually released through gears that power the hands and additional complications like the date and moon phase.
What makes automatic watches so remarkable is their ability to convert kinetic energy into mechanical energy. Automatic watches use your wrist movement to stay powered. It’s a smart way to turn movement into timekeeping.
Curious How Automatic Watches Power Themselves?
Automatic watches run on motion, not batteries, but how does that really work? Learn how rotors, mainsprings, and gear trains turn wrist movement into precise timekeeping.

Key Parts Of An Automatic Watch Movement
An automatic watch uses motion to power itself. The rotor spins as you move, winding the mainspring. Energy flows through gears, while the escapement and balance wheel control timing. These parts work together to move the hands smoothly. Each component is carefully built for accuracy, durability, and classic mechanical charm. Below is a table outlining the main components and their functions.
| Component | Description |
|---|---|
| Rotor | Semicircular weight that winds the mainspring via wrist motion |
| Mainspring | Coiled spring that stores mechanical energy |
| Gear Train | Series of gears that transmit energy to the hands |
| Escapement | Regulates energy release for consistent timekeeping |
| Balance Wheel | Oscillates to divide time into equal intervals |
What Is A Self-Winding Watch
A self-winding watch is simply another term for an automatic watch. The term “self-winding” highlights the innovation that sets automatic watches apart. It emphasizes the convenience of winding the mainspring through wrist movement rather than manual effort. This feature makes automatic watches ideal for daily wearers who prefer low-maintenance timepieces. It combines mechanical engineering with user-friendly design, offering a seamless experience for both casual and serious watch enthusiasts.
Self-winding watches differ from manual watches in that they don’t require daily winding. As long as the watch is worn regularly, the rotor keeps the mainspring wound. This automation reduces the risk of forgetting to wind the watch and ensures consistent performance.

Learn How to Keep Your Watch Running StrongHow Do Automatic Watches Power Themselves?
Automatic watches use your movement to stay powered. When you move your wrist, a small part inside the watch spins. This winds a spring that stores energy. That energy keeps the watch running. The amount of time it can run without moving is called the power reserve. Most watches last about 40-50 hours with some modern movements reaching 70-120 hours.. No batteries are needed, just motion.
Wearing the watch often helps it stay charged. Daily movement keeps the spring wound and the watch ticking. If you don’t wear it for a while, it will stop and need to be reset. People who switch between watches can use a watch winder. It mimics the motion of your wrist to keep the watch running. Regular wear also helps the watch stay accurate and in good shape.
Is A Mechanical Watch Better Than Automatic?
Automatic watches are actually a type of mechanical watch. Both use a mainspring to keep time and don’t need batteries. The only difference is how they’re wound. Traditional mechanical watches must be wound by hand, while automatic watches wind themselves using the motion of your wrist. This small difference can have a big impact on how convenient the watch is to use and how often it needs attention.
Manual mechanical watches offer a tactile experience and vintage charm, requiring daily winding for operation. This gives users control and a deeper connection to the watch, but it can be inconvenient for busy lifestyles. Manual watches offer reasonable precision though they may require frequent adjustment. These watches appeal to purists who value tradition and simplicity over automation.
Automatic watches wind themselves through wrist movement, offering greater convenience for daily wear. They’re ideal for users who prefer low-maintenance timepieces, though they may stop if unworn for days. Their complex movements can be costly to service, and accuracy varies slightly. Still, they strike a balance between heritage and practicality, making them a popular choice for modern enthusiasts.
Wondering which one you should choose? If you love tradition and enjoy interacting with your watch, a mechanical model offers a rewarding experience. It’s perfect for collectors, enthusiasts, or anyone who sees watch-winding as part of the charm. But if you prefer something reliable and low-maintenance for everyday use, go automatic. It’s ideal for professionals, commuters, or anyone who prefers a watch that keeps up without constant attention.

How To Properly Care For And Maintain Your Automatic Watch?
Wearing your automatic watch regularly keeps the internal rotor moving. If you own multiple watches, a watch winder can simulate wrist motion to keep the watch running.
To protect accuracy, avoid placing your watch near magnetic sources like speakers or magnetic clasps. Clean it gently with a soft cloth to remove moisture and debris. Ensure the crown is fully secured before water exposure, and store the watch in a cool, dry place.
Do Automatic Watches Stop When Not In Use?
Automatic watches stop when they aren’t worn for a while because their power reserve runs out. Depending on the movement, this reserve usually lasts between 40-50 hours. Once the mainspring fully unwinds, the watch stops until it’s manually rewound.
To restart some watches, follow the movement’s manual. This restores power and gets the movement going again. After winding, set the time and date, then wear the watch to keep it running. If you own several watches, a watch winder can help keep them active and save you from frequent resets.
How Long Can An Automatic Watch Last?
With proper care, automatic watches can last 20 to 30 years or more, often becoming family heirlooms. Their lifespan depends on movement quality, usage, and environment. Swiss movements are known for precision and durability, while Japanese movements offer reliable, cost-effective performance.
Watch servicing every 5-10 years keeps the movement clean and accurate. To protect your watch, avoid extreme conditions and store it in a cool, dry place away from magnets and moisture. At SÖNER Watches, we offer a 10-year warranty on our automatic watches to ensure lasting performance.
How Long Can An Automatic Watch Last Without Movement?
When not worn, an automatic watch relies on its power reserve to keep running. Most models offer a reserve between 40-50 hours, depending on the movement and design. Once the reserve is depleted, the watch will stop and require manual winding or renewed wrist movement to restart.
The power reserve is essentially the amount of energy stored in the mainspring. High-end watches may feature extended reserves of up to 5 days, while standard models typically last 1-2 days. If you plan to store your watch for longer periods, using a watch winder can help maintain the reserve and prevent the lubricants from settling.
Restarting a stopped watch is simple: wind the crown 20-40 times, set the time and date, and wear it to resume automatic winding. This ensures the movement remains active and accurate, even after periods of inactivity.
