Understanding Fortis Winding Settings
Every Fortis automatic watch has specific winding requirements determined by its movement caliber. The two key settings are:
- TPD (turns per day) — the number of rotations per 24 hours. Fortis movements in our database require between 650–800 TPD.
- Direction — clockwise (CW), counter-clockwise (CCW), or bidirectional. This depends on the rotor winding mechanism in each caliber.
Using the correct settings ensures your Fortis stays accurately wound without over-stressing the movement. The Time Machine app automatically applies the right profile for your specific model from our database of 14 Fortis references.
