How to determine which set rotation on watch winders

To determine the correct rotation settings on a watch winder, you need to identify whether your watch requires clockwise, counterclockwise, or bidirectional winding. This information is typically found in the watch's user manual or by consulting the manufacturer. Most modern watches can be wound in both directions, but some, especially older models or those with specific movements, may have a preferred direction. follow these key steps and considerations:

1. Identify Your Watch’s Winding Requirements

Check the watch manufacturer and model: Many watch brands and models have specific winding directions and turns per day (TPD) requirements based on their movement (caliber). You can often find this information:

Engraved on the back case or dial.

From the watch manual or manufacturer’s website.

By consulting the watch seller or online winding tables/databases.

Common winding directions:

Clockwise (CW): For watches designed to wind when rotated clockwise.

Counterclockwise (CCW): For watches that wind with counterclockwise motion.

Bidirectional: For watches that wind in both directions, alternating rotation is ideal.

2. Start with a Manual Wind
Before placing your watch on a winder, manually wind it by turning the crown about 20–30 times to ensure it has enough power reserve to start with

3. Set Initial Winder Parameters

Rotation direction: If you don’t have specific info, start with bidirectional rotation, as it suits most watches and mimics natural wrist movement.
Turns Per Day (TPD): Begin with a low TPD setting, around 650 to 700 turns per day, which fits most automatic watches, including popular brands like Rolex and Omega.

4. Trial and Adjustment

Place the watch in the winder and let it run for about 48 hours.
Check if the watch keeps accurate time.
If the watch runs slow or stops, increase the TPD gradually.
If timekeeping is still off, try changing the rotation direction to clockwise only or counterclockwise only to find the optimal setting.

5. Use Watch-Specific Winding Tables or Databases

Some websites and manufacturers provide winding tables listing the recommended TPD and rotation directions for many watch brands and calibers. Using these tables can save trial time and ensure proper settings.

Additional Tips

Choose a watch winder with adjustable TPD and rotation direction for flexibility, especially if you own multiple watches with different requirements.
Avoid overwinding by starting with the lowest TPD and increasing only if necessary.
Bidirectional rotation is generally the safest default if unsure, as it covers most winding mechanisms.

By following these steps, you can determine the optimal rotation setting on your watch winder to keep your automatic watch properly powered and running accurately without causing undue wear on its movement.This approach balances manufacturer guidance, trial, and watch winder flexibility to ensure the best care for your timepiece.
