Are you fascinated by the intricate world of horology? If so, you’ve probably heard of automatic self-winding watch. These marvels of engineering have been captivating watch enthusiasts for decades. In this comprehensive guide, we’ll explore how automatic self-winding watches work, debunk common misconceptions, and provide you with essential care tips to keep your timepiece ticking perfectly.

How Does an Automatic Watch Work?

An automatic self-winding watch, also known as an automatic self wind movement watch, is powered by the natural motion of the wearer’s wrist. The watch contains a weighted rotor that spins as the wrist moves, which in turn winds the mainspring. This stored energy is then released to power the watch’s movement, keeping it ticking accurately.

The rotor is connected to a gear train, which translates the spinning motion into energy that winds the mainspring. As the mainspring unwinds, it powers the watch’s movement, which consists of a series of gears and springs that regulate the timekeeping. The escapement, a crucial component of the movement, controls the release of energy from the mainspring, allowing the watch to keep accurate time.

It’s important to note that automatic watches must be worn regularly or stored in a self winding 

watch winder to maintain their power reserve. If an automatic watch is left unworn for an extended period, it will eventually stop running and require manual winding to restart.

Common Misconceptions About Automatic Watches

There are several common misconceptions about automatic watches that can lead to confusion and improper care. Let’s address each of these misconceptions and provide clarity on how automatic watches truly function.

• Automatic watches never need winding
  While it’s true that automatic watches are designed to wind themselves through the motion of the wearer’s wrist, they still require occasional manual winding. If an automatic watch hasn’t been worn for an extended period, it may need to be manually wound to restart and maintain its power reserve.
• Automatic watches can be overwound
  Many people fear that they might overwind their automatic watches, damaging the movement. However, automatic watches are designed with a slipping clutch mechanism that prevents overwinding. Once the mainspring is fully wound, the clutch disengages, preventing any damage to the watch.
• Automatic watches are less accurate than quartz watches
  While quartz watches are generally more accurate than automatic watches, modern automatic movements have made significant strides in accuracy. Many high-end automatic watches can maintain an accuracy of +/- 2 seconds per day, which is more than sufficient for most wearers.
• Automatic watches require constant motion to keep running
  Although automatic watches rely on motion to wind themselves, they don’t require constant motion to keep running. Most automatic watches have a power reserve of 40-50 hours, meaning they can continue running even when not being worn. However, if left unworn for longer periods, they may need manual winding to restart.
• Automatic watches are more expensive to maintain
  While automatic watches may require more frequent servicing than quartz watches, they are not inherently more expensive to maintain. With proper care and regular servicing every 3-5 years, an automatic watch can last a lifetime, making it a worthwhile investment for watch enthusiasts.

Step-By-Step Guide on How to Wind an Automatic Watch

While automatic watches are designed to wind themselves, there may be times when you need to wind them manually. Here’s a detailed guide on how to wind an automatic self-winding watch:

• Locate the crown: This is the small knob on the side of the watch case, typically at the 3 o’clock position. Some watches may have the crown at 4 o’clock for added comfort.
• Unscrew the crown: If your watch has a screw-down crown (common in dive watches and other water-resistant models), you’ll need to unscrew it first. Gently turn the crown counterclockwise until it pops out slightly.
• Wind the watch: Once the crown is in the winding position (usually the first position after unscrewing), gently turn it clockwise about 20-30 times. You should feel a slight resistance as you wind. This process transfers energy directly to the mainspring, bypassing the automatic winding mechanism.
• Set the time: After winding, if you need to set the time, pull out the crown to its furthest position. This is typically the third position for watches with a date function or the second position for watches without. Turn the crown to adjust the time, paying attention to the AM/PM indicator if your watch has one.
• Push and screw in the crown: Once you’ve set the time, push the crown back in and screw it down if applicable. This ensures the watch maintains its water resistance.

It’s worth noting that the winding direction can vary between watch models. While most automatic watches wind when the crown is turned clockwise, some models may wind counterclockwise. If you’re unsure, consult your watch’s manual or a professional watchmaker.

How to Care for Your Watch When You’re Not Wearing It

When you’re not wearing your automatic self-winding watch, it’s essential to care for it properly to ensure its longevity and accuracy. Here are some detailed tips:

• Use a watch winder: A watch winder for automatic watches is a device that mimics the motion of your wrist, keeping your timepiece wound and ready to wear. This is particularly useful if you have multiple watches and don’t wear each one daily. When choosing a watch winder, look for one with adjustable rotation settings to match your watch’s specific needs.
• Store it properly: Keep your watch in a cool, dry place away from direct sunlight. Excessive heat or humidity can damage the delicate components of your watch. Consider using a watch box or case with individual compartments to protect each timepiece from scratches and dust.
• Regular maintenance: Have your watch serviced by a professional every 3-5 years or as recommended by the manufacturer. During a service, the watchmaker will clean the movement, replace worn parts, and ensure all components are properly lubricated. This preventive maintenance can significantly extend the life of your watch.
• Avoid magnetism: Keep your watch away from strong magnetic fields, which can affect its accuracy. Common sources of magnetism include speakers, refrigerators, and some electronic devices. If your watch does become magnetized, a watchmaker can easily demagnetize it.
