Top Time B01 TPD & Winder Settings | Swiss Watch Store
An automatic like the Breitling Top Time B01 only stays accurate while its mainspring holds charge. This model carries reference AB0176. It is powered by the Calibre B01 movement. Set your winder to the figures below and the Top Time B01 stays wound, accurate and ready to pick up.
TPD and Winding Direction
The correct setting for the Top Time B01 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
The correct TPD mirrors what your wrist would do naturally across a normal day. It holds the mainspring at a healthy charge so the Top Time B01 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 Top Time B01
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 Top Time B01 flies solo; multi-watch winders make sense the moment you own two or more automatics. Our watch winder collection covers both.
