Watch Condition Checklist
Review visible condition clues and seller questions before buying, servicing, or sizing a watch.
A watch condition check should slow the purchase or service decision. Case, crystal, dial, hands, crown, movement information, strap, and records each answer a different question.
This checklist cannot authenticate a watch or guarantee service needs. Use qualified watchmakers, official service records, and reputable sellers for high-value decisions.

Fast checks
- Ask for photos from front, side, caseback, crown, clasp, and under strong light.
- Confirm case diameter, lug-to-lug, thickness, bracelet length, and service history.
- Save listing text and photos before payment.
- Use qualified authentication for high-value or frequently counterfeited watches.
What not to change yet
- Do not treat this page as authentication.
- Do not polish, replace, or service a watch before understanding value and originality implications.
- Do not rely on a seller’s vague serviced claim without details.
Assumptions and limitations
Photos can hide condition, replacements, moisture, and movement problems.
Authentication and servicing require qualified human inspection.
