Seamaster Planet Ocean TPD & Winder Settings | Swiss Watch Store
An automatic like the Omega Seamaster Planet Ocean only stays accurate while its mainspring holds charge. This model carries reference 215.30.44.21.01.001. It is powered by the Calibre 8900 movement. Set your winder to the figures below and the Seamaster Planet Ocean stays wound, accurate and ready to pick up.
TPD and Winding Direction
The correct setting for the Seamaster Planet Ocean is 650 turns per day, bidirectional: 650 turns per day with the rotor turning in both directions.
| Turns per day (TPD) | 650 |
| Rotation direction | Bidirectional |
| Movement | Calibre 8900 |
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 Seamaster Planet Ocean 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 Seamaster Planet Ocean
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 Seamaster Planet Ocean flies solo; multi-watch winders make sense the moment you own two or more automatics. Our watch winder collection covers both.
