Carrera Twin Time TPD & Winder Settings | Swiss Watch Store
The TAG Heuer Carrera Twin Time 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 WBN201A.BA0640. It is powered by the Calibre 7 movement. Below you'll find the exact TPD setting and winding direction the Carrera Twin Time needs.
TPD and Winding Direction
The correct setting for the Carrera Twin Time 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 7 |
Why the Correct Setting Matters
An automatic watch is only as accurate as its power reserve allows. Keep the mainspring properly tensioned and the Carrera Twin Time will hold its rate and be ready to wear the instant you pick it up — no resetting the time and date. Set the TPD too low and the watch can run down between wears. The movement will not be damaged (modern automatics have a slipping mainspring that prevents overwinding), but an under-wound watch is simply not doing its job. Correct settings are about accuracy and readiness, not safety.
Choosing a Watch Winder for the Carrera Twin Time
For the Carrera Twin Time, 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.
