Tag Heuer Movement Identification Guide
To identify your Tag Heuer movement, you can use the following methods:
1. Check the Case Back
Many Tag Heuer watches have the caliber number engraved on the case back. Look for “Calibre X” or “Cal X” near the model number.
2. Remove the Case Back
If the caliber is not visible, you’ll need to open the watch. Use a proper case opener to avoid damage.
3. Locate the Caliber Markings
- ETA/Sellita-based movements: Look for “ETA”, “SW”, or TAG Heuer markings on the rotor or mainplate.
- Heuer 01/02: Clearly marked on the rotor or visible through the case back.
- Zenith-based (Calibre 36): Marked with “Zenith” or “Calibre 36” on the rotor.
