How to Wind a Mechanical Watch: 3 Methods

Mechanical watches operate through intricate engineering. A mainspring rather than a battery drives them. The system is divided into two key categories: manual and automatic. Manual watches require deliberate winding to maintain energy, while automatic models harness motion from the wearer’s wrist to sustain function. Both types share a fundamental reliance on the mainspring, which stores and releases power in a controlled manner.

The mainspring, coiled within the barrel, dictates the energy supply. As it unwinds, power transfers through the gear train to regulate timekeeping. Automatic watches introduce a rotor, an oscillating weight that spins with motion. The rotor gradually tightens the mainspring to sustain power. Without movement, the watch stops, necessitating manual intervention to restart the operation.

This guide explores the nuances of mechanical watch winding, covering the differences between manual and automatic mechanisms, proper winding techniques, the role of watch winders, and essential maintenance practices to ensure longevity and precision. 

So, let’s get started.

Method 1: Winding a Manual Watch

Proper winding technique remains essential to preserve accuracy and longevity. A well-wound mainspring ensures steady power delivery, allowing the movement to function optimally. Neglecting routine winding can lead to timekeeping inconsistencies, while excessive force may damage internal components. Here’s how you can do it:

1. Remove the watch from your wrist before winding. This prevents undue pressure on the stem and reduces strain on internal parts.
2. Firmly grasp the crown, typically positioned at 3 o’clock, and rotate it clockwise in slow, deliberate turns. Smooth motion prevents unnecessary wear on gears.
3. Continue winding until firm resistance is felt. This indicates a fully wound mainspring. Most manual watches require 20 to 40 turns. Avoid forcing beyond this point to prevent damage.
4. Restore the crown to its resting position. If the watch features a screw-down crown, secure it properly to maintain water resistance and shield the movement from dust and moisture.
5. For daily wear, wind the watch simultaneously each day to sustain consistent power and accuracy.
6. Pay attention to the feel of the crown while winding. If resistance feels uneven or gritty, it may indicate an issue that requires servicing.
7. When returning the crown to its resting position, avoid overtightening. Secure it properly, but do not force it, as this could damage the threading or compromise water resistance.
8. If the watch is water-resistant, always ensure the crown is fully secured before exposing it to moisture to prevent water ingress.
9. Wind the watch before wearing it in the morning rather than at night for optimal accuracy, as mainspring tension affects timekeeping performance.

Method 2: Winding an Automatic Watch

While automatic watches self-wind through movement, certain situations require manual winding. Extended periods of inactivity deplete power reserves, making manual intervention necessary to restore function. Here’s how you can practice it:

1. If the watch remains unworn for several days, the movement stops due to a lack of motion. To restart it, manually wind the crown.
2. Rotate the crown clockwise around 20 to 30 times, ensuring the mainspring receives sufficient energy to resume operation.
3. Exercise caution while winding. Most automatic watches incorporate a slipping clutch to prevent overwinding, but excessive force can still strain the internal mechanism.
4. If the watch is worn infrequently, consider periodically winding it to maintain lubrication within the movement. This prevents oil from settling and ensures smooth operation.
5. Some automatic watches may allow for hand-winding even when worn. However, consistent motion from daily wear remains the most efficient way to keep the timepiece running.
6. If an automatic watch stops frequently despite regular movement, it may indicate insufficient wrist activity, requiring occasional manual winding.
7. Avoid shaking the watch aggressively to start the movement, which may cause internal damage. Instead, rely on controlled winding.
8. If the watch has a screw-down crown, ensure it is properly secured after winding to maintain water resistance and prevent dust or moisture infiltration.
9. If an automatic watch is frequently stored for long periods, occasional manual winding helps sustain lubrication and prevent the movement from drying out.
10. Consider servicing the watch periodically, as worn components or old lubricant can impact the self-winding efficiency.

Method 3: Using an Automatic Watch Winder

Consistent movement sustains an automatic watch’s performance, making a winder a practical solution. By mimicking the natural motion of the wrist, a winder keeps the mainspring engaged, ensuring the watch remains functional even when not worn for extended periods. Here’s how to do it:

1. A watch winder replicates wrist movement, preventing power depletion and maintaining the accuracy of the timepiece.
2. Select a winder with adjustable settings to match the watch’s specific needs, including rotation direction, speed, and turns per day (TPD). Different movements require different settings, so refer to the manufacturer's recommendations.
3. Ensure the watch is securely fastened within the winder to prevent unnecessary strain or misalignment during operation.
4. Avoid prolonged use if not needed. Overuse may cause excessive wear on the movement, particularly if the winder runs continuously without breaks.
5. Position the winder in a stable environment, away from extreme temperatures or magnetic interference, to preserve the watch’s accuracy and longevity.
6. Choose a winder that accommodates multiple watches if you own more than one automatic timepiece, ensuring convenience and efficiency.
7. If using a winder with multiple rotation modes, alternate settings periodically to prevent wear on a single rotational direction.
8. Verify that the winder’s motor operates silently and smoothly, as excessive noise may indicate mechanical stress that could affect the longevity of the watch movement.

Care and Maintenance Tips

Proper care and maintenance enhance the longevity and accuracy of mechanical watches. Regular winding, careful storage, and periodic servicing ensure smooth operation and preserve intricate craftsmanship. Understanding best practices for handling, storing, and maintaining these timepieces helps retain their reliability and value over time.

• Frequent Winding for New Watches: Newly acquired manual watches may require frequent winding until the mainspring reaches optimal tension.
• Proper Storage Conditions: Store mechanical watches in temperature-controlled environments to minimise lubricant degradation.
• Understanding Power Reserves: Most manual watches last 24-48 hours per full wind, while automatics depend on motion frequency.
• Magnetic Field Protection: Avoid exposing watches to strong magnetic fields, which may disrupt timekeeping accuracy and require demagnetisation.
• Water Resistance Maintenance: Periodically check water resistance ratings and have gaskets replaced if needed to prevent moisture damage.
• Regular Professional Servicing: Schedule professional servicing every three to five years to ensure the longevity and performance of the movement.

Mastering mechanical watch winding ensures precision, longevity, and consistent performance. Whether manually winding, engaging an automatic rotor, or utilising a winder, maintaining proper technique safeguards internal mechanics. A well-maintained watch preserves timekeeping accuracy and upholds the craftsmanship that defines mechanical horology.

Regular maintenance and proper handling prevent unnecessary wear, allowing the timepiece to function flawlessly for generations. Understanding the nuances of winding methods ensures that each component operates harmoniously, reinforcing the enduring value of mechanical watchmaking.
