Before you buy
- Match the reference and caliber to case-back and dial photographs. Review the movement type and any service documentation.
- Look for polishing, corrosion, replacement dials, hands, bands and missing links. A running watch is not proof of accuracy or water resistance.
- For auctions, review the end time, bid rules and wallet requirements. A bid is different from a fixed-price purchase request.
Reference numbers before rarity claims
A seller may use vintage, JDM or rare as a description. Check the full reference and model details against manufacturer information before treating those claims as established facts. The Seiko caliber reference is useful for identifying the relevant instruction manual, not for authenticating a resale watch.
Ask what was actually tested. Timekeeping, date changes, crown operation and service history are separate checks. For an older watch, budget for independent inspection rather than treating a listing photograph as a service certificate.
Compare the complete watch, not only its price
Compare two listings using the same full reference: record case size, movement or caliber, bracelet length, extra links and any documented service. A cheaper watch with a short bracelet or replacement dial is not the same offer as a complete example. For a specific model, refine the linked Seiko search with that reference rather than comparing every Seiko 5 or Prospex result together.
JPS basic receiving is not professional authentication or watch servicing. Review return and cancellation limits before committing to a high-value item.
From listing to international delivery
Use the purchase-request flow for eligible fixed-price listings. For auction listings, use the existing bidding flow and review the bid rules, wallet requirements and end time before committing.
