How to wind an automatic watch?

An automatic watch is a marvel of engineering, seamlessly blending craftsmanship and precision mechanics. Unlike quartz watches that rely on batteries, automatic timepieces harness the natural motion of your wrist to keep ticking. However, ensuring your watch maintains optimal function requires understanding how to correctly wind and maintain it. Here's your definitive guide.

Automatic watches, also known as self-winding watches, operate using kinetic energy derived from your wrist movements. Inside each automatic watch lies a rotor—a weighted, semicircular component—that spins freely, winding the mainspring. This mainspring stores energy, gradually releasing it to power the watch's movements.

Though your wrist motion usually keeps your automatic watch adequately wound, there are scenarios when manual winding becomes necessary:

• When you first acquire a watch or after long periods of non-use
• If your daily activities aren't sufficiently active
• To achieve optimal accuracy

Before winding, locate the crown, typically positioned at the 3 o'clock mark. Automatic watches generally have three crown positions:

• Position 1 (fully pushed in): normal operation
• Position 2 (partially pulled out): adjust date
• Position 3 (fully pulled out): set time

Ensure the crown is in position 1 for winding.

Gently rotate the crown clockwise. It's normal to feel slight resistance; this indicates that the watch is winding correctly. The number of turns required for a full wind varies by model—Longines watches may require anywhere from about 20 to 114 crown turns depending on the calibre.

Tip: avoid overwinding. Although automatic watches have built-in protection mechanisms to prevent damage, continuous excessive winding is unnecessary.

After winding, pull the crown to position 3 to set the correct time. If your watch has a date function, move the crown to position 2 to adjust it accurately. Always ensure the crown is returned fully to position 1 afterward to maintain water resistance.

Proper winding is just one aspect of maintaining your automatic watch. Follow these essential practices:

• Regular wear: daily wear helps maintain consistent winding.
• Use of watch winders: ideal if you own multiple automatic watches or rotate wear frequently.
• Periodic servicing: schedule professional servicing every 3-5 years to maintain peak performance with a Longines certified service center.

Even seasoned watch enthusiasts occasionally make errors. Here are a few pitfalls to avoid:

• Adjusting the date at midnight: The restricted time window can vary depending on the calibre fitted in the watch. Refer to your user guide for the exact range. For many models, it is between 9 p.m. and 3 a.m., when the date mechanism is engaged.
• Insufficient winding: occasional short winding will not provide adequate energy. Ensure sufficient turns for full power reserve.
• Ignoring servicing: regular maintenance avoids mechanical wear, lubrication loss, and ensures longevity.

Automatic watches are precise instruments, but issues occasionally arise:

While minor adjustments and winding can be handled personally, seek expert assistance when:

• The watch consistently loses or gains significant time
• There's noticeable moisture inside the crystal
• The watch fails to start after manual winding

Understanding how to wind and maintain an automatic watch deepens your appreciation for this intricate piece of horological artistry. Proper care ensures not only longevity but sustained accuracy, allowing you to cherish your automatic watch for generations.

Whether you're a seasoned collector or a first-time automatic watch owner, mastering proper winding techniques guarantees reliable performance and preserves your timepiece's elegance and precision.
