Marathon Watch Winder Settings (TPD)

Every automatic watch has a recommended winding routine. Below are the turns per day (TPD) and rotation direction settings for 3 Marathon models and calibres. Most Marathon automatics wind at 650 TPD, direction: both directions.

If your exact model isn't listed, look for its movement/calibre instead — brands often share the same movement across many models. When in doubt, 650 TPD bi-directional is a safe setting for most modern automatics.
