Automatic watches, revered for their intricate engineering and timeless elegance, are marvels of horological craftsmanship. Despite their sophistication, many owners find themselves puzzled when their automatic watches stop unexpectedly. Understanding the reasons behind this issue requires a deep dive into the mechanics, maintenance, and user habits related to these sophisticated timepieces. This article aims to elucidate the common causes and solutions for an automatic watch that keeps stopping, providing insights to ensure your watch continues to perform optimally.
Understanding the Mechanics of an Automatic Watch
An automatic watch, also known as a self-winding watch, is powered by the movement of the wearer’s wrist. Unlike quartz watches that run on batteries, automatic watches rely on a complex interplay of mechanical components. The key elements include:
Rotor: A semi-circular piece that swings with wrist movement, winding the mainspring.
Mainspring: Stores energy and releases it to power the watch.
Gear Train: Transfers energy from the mainspring to the escapement.
Escapement: Regulates the release of energy to maintain accurate timekeeping.
Balance Wheel: Works with the escapement to ensure consistent time intervals.
Common Causes of Automatic Watch Stoppage
1. Insufficient Wrist Movement
One of the most prevalent reasons for an automatic watch to stop is insufficient wrist movement. These watches rely on regular movement to keep the mainspring wound. If you lead a sedentary lifestyle or do not wear your watch regularly, it may not receive enough movement to stay wound.
Solution: Wear your watch consistently, ideally for at least 8 hours a day. If your lifestyle doesn’t allow for this, consider using a watch winder, a device that keeps your watch moving when it’s not being worn.
2. Low Power Reserve
The power reserve of an automatic watch refers to how long the watch will run without additional winding. Most automatic watches have a power reserve ranging from 38 to 72 hours. If your watch stops after a day or two off the wrist, it could simply be that the power reserve has been depleted.
Solution: To avoid this, manually wind your watch by rotating the crown (typically clockwise) about 20-40 times, depending on the model, to fully charge the mainspring.
3. Dirt and Lubrication Issues
Over time, dust, dirt, and dried lubricants can accumulate within the watch’s movement, causing increased friction and reduced efficiency. This can lead to stoppage, especially if the watch hasn’t been serviced regularly.
Solution: Regular maintenance is crucial. Most manufacturers recommend servicing your automatic watch every 3 to 5 years. During servicing, a professional watchmaker will clean, lubricate, and calibrate the movement, ensuring it runs smoothly.

4. Magnetization
Exposure to magnetic fields is a common issue that can affect the performance of automatic watches. Everyday items such as phones, speakers, and magnetic clasps can magnetize the delicate components of the watch, causing it to stop or run inaccurately.
Solution: Avoid placing your watch near strong magnets. If you suspect magnetization, take your watch to a professional. They can demagnetize it using specialized equipment.
5. Mechanical Issues and Wear
Despite their durability, the mechanical parts of an automatic watch are subject to wear and tear. Components like the balance wheel, rotor, and escapement can wear out over time, leading to stoppage or inconsistent timekeeping.
Solution: Regular servicing can mitigate wear and tear. If a specific part is worn out or damaged, a watchmaker can replace it, ensuring the watch continues to function properly.
How to Wind and Set an Automatic Watch
Manual Winding
Even though automatic watches are designed to wind themselves, manual winding can help ensure they remain fully powered, especially if you don’t wear them daily.
Position: Hold the watch with the crown facing you.
Grip: Gently pull the crown out to the first position.
Wind: Turn the crown clockwise about 20-40 times. You should feel a slight resistance indicating the mainspring is fully wound.
Setting the Time and Date
Time Setting: Pull the crown to the second position. Turn the crown to set the time, ensuring the hands move forward.
Date Setting: Push the crown back to the first position. Turn the crown to set the date. Avoid setting the date between 9 PM and 3 AM, as this can damage the date mechanism.
Proper Care and Maintenance Tips
1. Regular Wearing
Wearing your automatic watch regularly helps keep the movement in good condition. The natural motion of your wrist ensures the mainspring remains wound and the lubricants are evenly distributed.
2. Safe Storage
When not wearing your watch, store it in a safe, dry place. A watch box or case with a soft lining can protect it from dust and scratches. If you have multiple watches, consider a watch winder for those you don’t wear frequently.
3. Avoid Water Exposure
Unless your watch is specifically designed for diving, avoid exposing it to water. Even if it’s water-resistant, frequent exposure can degrade the seals over time. Always ensure the crown is pushed in or screwed down to prevent water ingress.
4. Handling with Care
Avoid dropping or hitting your watch against hard surfaces. The intricate mechanisms inside are sensitive to shocks, which can lead to misalignment or damage.

5. Regular Servicing
Adhere to the manufacturer’s recommended service intervals. Regular servicing by a qualified watchmaker ensures that your watch remains in optimal condition, prolonging its lifespan.
Choosing the Right Automatic Watch
Selecting an automatic watch involves considering several factors to ensure it meets your lifestyle and preferences.
1. Brand Reputation
Choose reputable brands known for their quality and craftsmanship. Brands with a long history in watchmaking often provide more reliable and durable timepieces.
2. Movement Quality
The movement is the heart of the watch. Swiss movements, like those from ETA or Sellita, are renowned for their precision and reliability. Japanese movements from Seiko or Miyota are also highly regarded for their durability and affordability.
3. Power Reserve
Consider the power reserve based on your wearing habits. If you don’t wear your watch daily, a longer power reserve (50+ hours) might be beneficial.
4. Material and Build Quality
Look for watches with robust materials, such as stainless steel, sapphire crystal, and high-quality leather or metal straps. These materials enhance durability and aesthetic appeal.
5. Features and Complications
Consider additional features like date functions, chronographs, or GMT indicators based on your needs. However, remember that more complications can require more maintenance.
Conclusion
Automatic watches are not just timekeeping devices; they are pieces of art and engineering. Understanding why your automatic watch keeps stopping involves recognizing the delicate balance of mechanical components and the importance of regular maintenance and proper usage. By addressing common issues such as insufficient wrist movement, low power reserve, dirt and lubrication problems, magnetization, and mechanical wear, you can ensure your watch remains a reliable and cherished accessory for years to come. Investing time in learning about your watch’s mechanics, proper care techniques, and selecting the right watch for your needs will enhance your appreciation and enjoyment of this timeless technology.
