Date and no-date models, aluminium and ceramic bezel generations, case proportions, bracelet systems, lume, and calibres differ. A mixed-generation checklist creates false positives.
Identify the generation and configuration
Date and no-date models, aluminium and ceramic bezel generations, case proportions, bracelet systems, lume, and calibres differ. A mixed-generation checklist creates false positives.
Record the claimed reference before comparing details.
- Separate date from no-date models
- Check bezel and case generation
- Confirm bracelet configuration
Review geometry before micro-details
Assess lug and crown-guard profile, bezel action and insert, crystal seating, rehaut relationship, dial spacing, hands, bracelet taper, clasp, and finishing as a system.
Refinishing and service replacement parts can change a genuine watch.
- Use straight side and front views
- Check alignment around the full bezel
- Document wear and polish
Check operation without forcing it
Winding, setting, date change where present, bezel rotation, clasp, and bracelet should operate consistently with the reference and condition. Do not infer water resistance from crown feel.
Stop if a control binds or behaves unexpectedly.
- Avoid forced date changes
- Pressure-test before immersion
- Have abnormal operation examined
Move from screening to authentication
A serial number, photograph, seller story, or single visual detail cannot authenticate a watch. Use the manufacturer or a qualified independent expert for a conclusion.
Internal examination should identify architecture and condition while recognizing that markings and decorative components can be copied.
- Use reference-specific documentation
- Have case opening done competently
- Request a scoped written conclusion
QUICK ANSWERS
Frequently asked questions
Is the date magnifier a definitive test?
No. Magnification and alignment are useful observations but not conclusive authentication.
Does bezel sound prove authenticity?
No. Feel and sound vary with reference, condition, contamination, and service.
Can a service dial or bracelet be genuine?
Yes, replacement parts may be genuine, but configuration and disclosure still require careful review.
