Automatic watches are self-winding under normal wear conditions, but many wearers don’t know how to manually wind them — which is essential knowledge for getting an unworn watch started, or for wearing it intermittently. Here’s the complete guide.
Why Manual Winding is Sometimes Necessary
An automatic watch that’s been sitting unworn for more than 48 hours (typical power reserve) will have stopped completely. While you can set it on your wrist and let arm movement wind it, this takes time and the watch will be inaccurate until fully powered. Manual winding gets it fully powered immediately.
How to Wind Your Automatic Watch
- Unscrew the crown if your watch has a screw-down crown (Rolex, Omega Seamaster, etc.) — turn counterclockwise until it pops out to the first position
- Turn the crown clockwise (when viewed from the side) in smooth, continuous rotations
- Count approximately 20-30 turns for a fully depleted movement — you’ll feel slight resistance as the mainspring reaches full tension
- Do NOT over-wind — modern automatic movements have slip clutches that prevent damage, but develop the habit of stopping when you feel significant resistance
- Push the crown back in (and screw it down if applicable)
Important Notes
- Always wind with the watch off your wrist — wrist motion puts stress on the crown and stem
- Some movements (including older Seiko 7S26 in SKX007) do NOT have manual winding capability — let them wind naturally through wear
- For hacking movements (seconds hand stops when crown is pulled), use this feature to set time precisely to the second
