The Lost Designer standard
Pre-Owned Seiko Watches in Australia
Shop authenticated pre-owned Seiko watches currently available through Lost Designer. Each listing documents the case, dial, crystal, bracelet or strap, movement information, visible condition and exact box, papers or service inclusions where available.
Each Seiko watch is reviewed by two authenticators and authenticated through LegitApp. We inspect the dial, case, bezel, crystal, crown, caseback, bracelet or strap, clasp and visible identifying details where applicable, then document condition and wear with detailed descriptions and clear photography.
Each item is one of a kind. Shop online with complimentary, tracked and fully insured express delivery across Australia, or inspect a piece at our Toorak boutique during opening hours—no appointment is required.

Read our authenticity promiseHow is the condition of each Seiko watch assessed?
We assess the case, bezel, crystal, dial, crown, caseback, bracelet or strap and clasp. The listing documents visible scratches, chips, dents, wear, bracelet stretch and signs of polishing or refinishing where identifiable.
