Premier B01 42 TPD & Winder Settings | Swiss Watch Store
The Breitling Premier B01 42 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 AB0118. It is powered by the Calibre B01 movement. Below you'll find the exact TPD setting and winding direction the Premier B01 42 needs.
TPD and Winding Direction
The correct setting for the Premier B01 42 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 B01 |
Why the Correct Setting Matters
Too few turns and the Premier B01 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 Premier B01 42
For the Premier B01 42, look for a programmable winder offering a 800 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.
