Gear & Authenticity

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.

Condition and authenticity are different questions, and mixing them is how buyers get hurt. A genuine watch can be in poor condition, and a well-kept fake can pass a casual glance; this checklist addresses the first question only. Its real value is negotiating and deciding: a crisp case with a tired movement prices differently from a polished-out case with fresh service papers, and knowing which one you are looking at is the difference between a fair deal and an expensive lesson.

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.
