Seamaster 300M (older, pre-2018) TPD & Winder Settings | Swiss Watch Store
Wondering how to programme your watch winder for the Omega Seamaster 300M (older, pre-2018)? You are in the right place. This model carries reference 2531.80.00. It is powered by the Calibre 1120 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 Seamaster 300M (older, pre-2018) 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 | Calibre 1120 |
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 300M (older, pre-2018) 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 300M (older, pre-2018)
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 Seamaster 300M (older, pre-2018) flies solo; multi-watch winders make sense the moment you own two or more automatics. Our watch winder collection covers both.
