Automatic watch winder settings

To set the automatic watch winder settings correctly, you need to adjust two main parameters: rotation direction and turns per day (TPD). Here is a detailed guide based on expert recommendations:

1. Rotation Direction

Watch winders typically offer three rotation modes:

• Clockwise (CW)

• Counterclockwise (CCW)

• Bidirectional (both clockwise and counterclockwise)

The correct direction depends on your watch's movement. Some watches wind only clockwise, others counterclockwise, and many work with bidirectional motion. If you are unsure of your watch’s winding direction, a good starting point is to use bidirectional rotation for testing.

2.  Turns Per Day (TPD)

TPD is the number of rotations the winder makes per day to keep your watch wound without overwinding. Most automatic watches require between 650 and 1200 TPD.

• Start at the lowest recommended TPD (around 650).

• Run the winder for about 48 hours and check if the watch keeps accurate time.

• If the watch runs slow, increase TPD gradually until optimal timekeeping is achieved.

• If your watch model is known, you can use specific manufacturer-recommended TPD and direction settings available in watch winder databases for precision.

3.  Manual Winding

Before using the winder, manually wind your watch by turning the crown 20-30 times to ensure it has enough power to start the winding process.

Step-by-Step Setup

1. Manually wind the watch (20-30 crown turns).

2. Set the winder to lowest TPD (e.g., ~650 TPD).

3. Set rotation to bidirectional.

4. Place the watch securely in the winder.

5. Run for 2 days and check accuracy.

6. If inaccurate, increase TPD stepwise.

7. If still inaccurate, try switching rotation direction to one-way (CW or CCW).

8. If none of these work, the watch may need servicing.

Additional Tips

• Refer to your watch’s caliber or model for exact winder settings if available.

• Avoid overwinding by not exceeding recommended TPD.

• Regularly check time accuracy to ensure proper winding.

This approach ensures your automatic watch remains wound, accurate, and well-maintained without unnecessary wear
