History, with context
Historical serial lookup
Explore historical dating estimates for five watch brands, with clear coverage limits and practical guidance.
Serials can be copied, reused or attached to replacement components. A match is not proof that a watch is genuine; an unsupported number is not proof that it is counterfeit. Production, assembly, delivery and sale dates can differ.
Use the appropriate case number, movement number or separate date code. Do not open your watch yourself to find a number.
About Historical Serial-Number Dating
Historical estimates are based on available production records, manufacturer information, and established reference data. Coverage and accuracy vary by brand, model, and production period.
Results are provided for informational purposes only and should not be considered proof of authenticity, an exact manufacturing date, or a professional appraisal.
Need the watch examined?
Our independent authentication service includes a documented report: $100 for photographic review or $300 for physical examination. The historical lookup is free and separate.
