Automatic timepieces exemplify horological engineering, operating without batteries by harnessing energy from your wrist movements. This sophisticated design showcases a blend of traditional craftsmanship and modern innovation, captivating collectors and enthusiasts alike, while highlighting the intricate mechanics behind these remarkable self-winding timepieces.

For a deep dive on automatic watches, read our article on: What Is An Automatic Watch?

Automatic watches use a rotor that spins with the motion of your wrist to generate energy—no battery required. This self-winding mechanism stores power in a coiled spring and releases it through a series of gears and components that keep time with mechanical precision. With regular servicing, they can run reliably for decades.

An automatic watch movement is a complex assembly of over 160 microscopic components that work harmoniously to keep precise time. Each part plays a vital role in the watch's functionality and performance, showcasing the intricate craftsmanship involved in horology. One of the most reliable and compact calibres used in luxury automatic timepieces is the ETA-2671 automatic movement, known for its durability, thin profile, and precision engineering. Learn about the key movement components and functions of this impressive Swiss movement below.

Most modern automatic watches offer a power reserve of 36-42 hours. If not worn daily, be prepared for your watch to require manual winding or resetting after several days. Understanding your watch's power reserve helps you manage its usage effectively.

For winding a self-winding watch, hold the watch head in your left hand and use your thumb and index finger to turn the crown upward about 30 times. Some timepieces may require you to unscrew the crown first. Most modern automatics feature a slipping mainspring to prevent over-winding, allowing safe winding without risk of damage. If you haven’t worn your watch for a day or two, manual winding is likely needed to ensure accurate timekeeping.

Proper time and date setting are crucial to maintaining the accuracy and longevity of your watch. Avoid turning the crown backward if you overshoot the time, and do not adjust the date during the “danger zone,” as this can damage the date-change mechanism.

• To Set the Time:Pull the crown out to time-setting mode. Turn it clockwise to set the minute and hour hands. Ensure that the date changes at midnight, not noon. If you pass your desired time, continue rotating forward to reach it.
• To Set the Date:Pull the crown to the date-setting position and rotate it clockwise. Avoid setting the date between 9pm and 3am, as this can damage the date mechanism.

If your automatic watch is water-resistant, always ensure the crown is fully pushed in or screwed down before exposing it to water. Check the ATM rating for water resistance and have it tested regularly to ensure the seal remains effective, especially after repairs.

Water resistance is measured in ATM (atmospheres) or meters, with 1 ATM equal to 10 meters of pressure.

• 3 ATM (30m):Splash-resistant, not suitable for swimming or bathing.
• 5 ATM (50m):Can handle showering or light swimming.
• 10 ATM (100m):Suitable for swimming and snorkelling.
• 20 ATM (200m):Ideal for diving.

Regularly winding your watch and wearing it frequently will keep it functioning optimally. Familiarize yourself with the watch’s crown and its functions for setting the time and date accurately. Following the guidelines outlined above will maximize your watch's functionality and longevity.

Proper storage is key to preserving your watch. Keep it in a dedicated luxury watch box to minimize dust exposure. Store your automatic watch in a cool, dry place, away from extreme temperatures, humidity, and direct sunlight, which can damage the movement and affect its performance. For daily use, a watch stand or watch tray keeps your timepiece organized and protected. If you have multiple watches, consider using a watch winder to ensure they keep running smoothly and prevent the lubricants from settling, which can affect accuracy.

Since self-winding timepieces rely on wrist movement to wind the mainspring, an automatic watch winder simulates this motion to ensure the movement continues to function properly. When placed inside the winder, the watch rotates periodically, preventing the lubricants inside the movement from settling, which can affect accuracy. Make sure the winder’s settings are compatible with your watch’s specific movement, as different movements may require different winding directions or rotations. Using a watch winder helps maintain your watch’s performance and reduces the need for frequent manual winding.

To ensure your automatic watch remains in top condition, follow a consistent care routine that includes regular cleaning, proper storage, and timely servicing. Make sure to wipe your watch after each wear and avoid exposing it to harsh elements. It’s essential to have your watch professionally serviced every 3 to 5 years to keep it running accurately. This servicing includes cleaning, lubrication, and necessary adjustments to maintain performance and prevent costly repairs down the road.
