PRX Powermatic 80 TPD & Winder Settings | Swiss Watch Store

Own a Tissot PRX Powermatic 80, reference T137.407? Getting the winder settings right means the difference between a watch that is always running accurately and one that keeps stopping between wears. Powered by Powermatic 80.111 , this model needs a specific number of turns per day and the correct rotation direction. Here is everything you need to set your winder up correctly.

Settings at a glance

  • Turns per day: 650 turns per day
  • Winding direction: bidirectional (rotating both ways)

These two figures are all you need. Set them on any programmable winder and your PRX Powermatic 80 will stay at a full, healthy power reserve between wears.

Why bother getting it right?

Because a stopped watch is an annoying watch. When your PRX Powermatic 80 drops below its power reserve, you face resetting the time, the date and any other complications before you can wear it. Dialling in the correct TPD means the watch is always running and holding accurate time, ready the moment you are. A quick reassurance: if the setting is slightly off, modern automatics are protected by a slipping mainspring, so nothing breaks — you just lose the accuracy and readiness benefits.

What to look for in a winder

Three things matter for the PRX Powermatic 80: adjustable TPD, selectable winding direction, and enough slots for your collection. A quality programmable winder ticks the first two easily — the third is personal. Single winders suit a one-watch rotation; multi-watch winders suit anyone juggling several automatics.
