Seamaster Diver 300M TPD & Winder Settings | Swiss Watch Store
The Omega Seamaster Diver 300M is an automatic watch: it winds itself from the motion of your wrist, but on the days it sits unworn a watch winder keeps the mainspring topped up. This model carries reference 210.30.42.20.03.001. It is powered by the Calibre 8800 movement. Below you'll find the exact TPD setting and winding direction the Seamaster Diver 300M needs.
TPD and Winding Direction
The correct setting for the Seamaster Diver 300M 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 8800 |
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 Diver 300M 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 Diver 300M
For the Seamaster Diver 300M, look for a programmable winder offering a 650 TPD bidirectional programme. One watch? A single winder. Two or more automatics? A double or triple winder keeps the whole rotation ready. You'll find suitable models in our watch winder collection — check the programme list before you buy.
