How do you adjust a watch winder

To adjust a watch winder, you need to configure the turns per day (TPD) and rotation direction based on your watch's specific requirements. Start by manually winding your watch and then place it in the winder, selecting the lowest TPD setting and bidirectional rotation mode. Observe your watch's timekeeping over 48 hours. If it's inaccurate, adjust the TPD or rotation direction accordingly. Follow these steps:

Manually wind your watch first: Before placing your watch in the winder, manually wind it by turning the crown about 20 to 30 times until you feel slight resistance. This ensures the watch has enough initial power, as a completely stopped watch will not wind effectively in the winder.

Place the watch securely in the winder: Remove the cushion or holder from the winder, place your watch around it so it fits snugly but not too tight, then insert the cushion back into the winder. Make sure the watch is fully seated and stable to avoid damage during rotation.

Set the Turns Per Day (TPD): Start with the lowest TPD setting on your winder, typically around 650 turns per day. This setting controls how many rotations the winder makes in a day and should match your watch’s specifications to avoid overwinding or underwinding.

Select the rotation direction: Most winders offer three rotation modes—clockwise only, counterclockwise only, or bi-directional (alternating directions). Check your watch’s manual or manufacturer recommendations to determine the correct winding direction. If unknown, start with bi-directional mode.

Turn on the winder and monitor: Power on the winder and let it run for about 48 hours. Periodically check if your watch is keeping accurate time. If the time remains correct after two days, the setting is appropriate.

Adjust if necessary: If the watch is losing or gaining time, increase the TPD to the next level and repeat the process. If time accuracy issues persist, try changing the rotation direction—first to clockwise only, then counterclockwise only—to find the optimal setting for your watch.

Regular monitoring: Even with a winder, periodically check your watch’s timekeeping and condition to ensure it remains in good working order.

By following these steps, you can adjust your watch winder box to maintain your automatic watch’s power reserve and accuracy efficiently without risking damage or overwinding.
