Seastar 1000 Powermatic 80 TPD & Winder Settings | Swiss Watch Store
Every automatic watch has a sweet spot for winding, and the Tissot Seastar 1000 Powermatic 80, reference T120.407 is no exception and the Powermatic 80 (ETA C07.111), with its automatic calibre listed above. Rather than guessing, this page gives you the verified turns-per-day (TPD) figure and winding direction for the Seastar 1000 Powermatic 80, so you can dial in your winder with confidence.
Winder settings for the Seastar 1000 Powermatic 80
Set your winder to between 650 and 800 turns per day with a bidirectional (rotating both ways) rotation. That is the combination this model is designed for. Most programmable winders let you select both the TPD and the rotation mode, so matching these figures is straightforward.
The point of precise winding
It comes down to readiness and accuracy. A Seastar 1000 Powermatic 80 kept at its ideal TPD maintains a full power reserve, which is when automatic movements run most consistently. Let the reserve run down and the watch stops — then it is the familiar ritual of resetting everything. One thing not to worry about: an incorrect winder setting cannot damage a modern automatic watch. The slipping mainspring guards against overwinding, so getting the setting right is about performance and convenience, not safety.
Picking your winder
Keep it simple: choose a programmable winder, enter the TPD and direction above, and your Seastar 1000 Powermatic 80 takes care of itself. Capacity is the only real decision — a single-watch winder if this is your main piece, a two- or four-watch model if you like to rotate. All the winders you need are in our watch winder collection.
