Royal Oak Selfwinding 41 TPD & Winder Settings | Swiss Watch Store

Set your winder to the figures below and the Royal Oak Selfwinding 41 stays wound, accurate and ready to pick up.

| Turns per day (TPD) | 650 |
| Rotation direction | Bidirectional |
| Movement | Cal. 4302 |
Why the Correct Setting Matters
The correct TPD mirrors what your wrist would do naturally across a normal day. It holds the mainspring at a healthy charge so the Royal Oak Selfwinding 41 runs at its best and is ready to wear at a moment's notice — exactly what a watch winder is for.
Don't worry if you're unsure — you can't break a modern automatic with the wrong winder setting; the slipping bridle on the mainspring makes overwinding impossible. The right setting just keeps everything running at its best.
Choosing a Watch Winder for the Royal Oak Selfwinding 41
The key feature to shop for is programmability: independent TPD and direction controls that cover 650 TPD bidirectional. Single-watch winders are ideal if the Royal Oak Selfwinding 41 flies solo; multi-watch winders make sense the moment you own two or more automatics. Our watch winder collection covers both.
