How to Inspect a Pre-Owned Watch Before Buying

Keep a written record of the exact model reference, seller description and warranty terms. When a claim is model-specific, confirm it in the current instruction manual or on the manufacturer's official support page.

Common mistakes to avoid

• Assuming box and papers prove that the watch itself is authentic.
• Judging movement health from a short video alone.
• Paying a collector premium without understanding originality and condition.

If information is missing or contradictory, pause the purchase or use. A cautious answer based on the exact model is more useful than a confident guess.

A simple decision rule

Choose the option that meets your normal use with the fewest unsupported assumptions. Pay for features you understand and will use. For water exposure, repairs, battery replacement, pressure testing or movement problems, follow the manufacturer and use a qualified service professional.

Frequently Asked Questions

Does polishing reduce value?

It can for some collectible watches, especially when case geometry is altered; value impact is model and buyer dependent.
