What Is an Automatic Watch and How Does It Work?
How They Work, Why They Matter, and How to Care for Them
Automatic watches are more than just instruments for telling time—they are miniature marvels of mechanical engineering. Unlike quartz watches that rely on batteries, automatic watches are powered by the natural motion of your wrist, offering a fascinating fusion of tradition, innovation, and timeless appeal.
Whether you’re a seasoned collector or just beginning your horological journey, this guide will walk you through how automatic watches work, their benefits, and how to care for them properly.
What Is an Automatic Watch?
An automatic watch, also known as a self-winding watch, is a type of mechanical timepiece that winds itself using the movement of the wearer’s wrist. Inside the watch is a rotor—a semicircular weight that swings with your motion, winding the mainspring. This stored energy powers the gears and keeps the watch running, no battery required.
Many automatic watches feature exhibition case backs, letting you admire the intricate craftsmanship within—rotors made of gold, platinum, or tungsten are often visible in motion, adding both elegance and functionality.
How Do Automatic Watches Work?
The magic behind an automatic watch lies in its rotor mechanism. As you move throughout the day, the rotor spins and winds the mainspring, which then transfers energy through a series of gears and escapements to keep accurate time.
Most automatic watches also allow for manual winding via the crown, which can be useful if the watch hasn’t been worn for a few days.
Quick Tip:
If your watch has stopped, you can gently shake it or manually wind it about 20–30 turns clockwise to restart the movement.
Do Automatic Watches Need Manual Winding?
Not usually—regular wear keeps your watch powered. However, occasional manual winding can help maintain power and accuracy, especially if the watch has been idle.
Important Notes:
🔄 Manual Winding: Turn the crown clockwise 20–30 times.
👋 Daily Wear: Keeps the watch naturally wound.
⛔ No Overwinding: Most modern watches feature a slip clutch to prevent damage.
If your automatic watch isn’t keeping time properly, it may need servicing. Precision Watches offers expert diagnostics and repair services for all luxury brands.

Caring for Your Automatic Watch
With the right care, your automatic watch can last for decades—or even centuries.
Maintenance Tips:
Wear Regularly: Keeps the internal components lubricated.
Avoid Extremes: Stay away from intense heat, cold, and magnetic fields.
Store Safely: Use a soft cloth or case to protect it when not in use.
Service Every 3–5 Years: Routine maintenance keeps your watch in peak condition.
Investing in a Watch Winder
If you rotate between multiple watches, a watch winder is a smart investment. It mimics wrist motion, keeping your timepiece wound and ready to wear.
Look for a winder with adjustable settings to match your watch’s movement and avoid overwinding.
A Brief History of Self-Winding Watches
The concept of self-winding timepieces dates back to the 18th century. Swiss watchmaker Abraham-Louis Perrelet is credited with developing the first self-winding pocket watch in the 1770s. Decades later, in 1923, John Harwood created the first automatic wristwatch—a pivotal moment that shaped the future of horology.
Today, automatic movements remain a powerful symbol of craftsmanship and tradition.
