Portugieser Yacht Club Chronograph TPD & Winder Settings | Swiss Watch Store
Wondering how to programme your watch winder for the IWC Portugieser Yacht Club Chronograph? You are in the right place. This model carries reference IW390704. It is powered by the IWC Calibre 89361 movement. Below are the correct TPD and rotation-direction figures for this model, so your watch is always ready to wear.
TPD and Winding Direction
The correct setting for the Portugieser Yacht Club Chronograph is 800 turns per day, bidirectional: 800 turns per day with the rotor turning in both directions.
| Turns per day (TPD) | 800 |
| Rotation direction | Bidirectional |
| Movement | IWC Calibre 89361 |
Why the Correct Setting Matters
Too few turns and the Portugieser Yacht Club Chronograph stops between wears; the right figure keeps the mainspring in its sweet spot, where the movement runs most consistently. And there is no risk in experimenting: a modern automatic cannot be overwound on a winder, because the mainspring's slipping bridle releases excess tension. Getting the setting right is about convenience and accuracy, never about avoiding damage.
Choosing a Watch Winder for the Portugieser Yacht Club Chronograph
The key feature to shop for is programmability: independent TPD and direction controls that cover 800 TPD bidirectional. Single-watch winders are ideal if the Portugieser Yacht Club Chronograph flies solo; multi-watch winders make sense the moment you own two or more automatics. Our watch winder collection covers both.
