Seamaster Bullhead TPD & Winder Settings | Swiss Watch Store
An automatic like the Omega Seamaster Bullhead only stays accurate while its mainspring holds charge. This model carries reference 225.12.43.50.01.001. It is powered by the Calibre 3113 movement. Set your winder to the figures below and the Seamaster Bullhead stays wound, accurate and ready to pick up.
TPD and Winding Direction
The correct setting for the Seamaster Bullhead 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 3113 |
Why the Correct Setting Matters
Too few turns and the Seamaster Bullhead 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 Seamaster Bullhead
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 Bullhead flies solo; multi-watch winders make sense the moment you own two or more automatics. Our watch winder collection covers both.
