Superocean Automatic 42 TPD & Winder Settings | Swiss Watch Store
Left unworn, the Breitling Superocean Automatic 42 will run down within a couple of days — a correctly set watch winder stops that happening. This model carries reference A17375. It is powered by the Calibre B17 movement. Here is the TPD and direction this model calls for.
TPD and Winding Direction
The correct setting for the Superocean Automatic 42 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 B17 |
Why the Correct Setting Matters
Too few turns and the Superocean Automatic 42 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 Superocean Automatic 42
For the Superocean Automatic 42, 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.
