The five options
- WatchRadar — iPhone five-angle scan, region-by-region dossier, signed certificate. Free download, per-certificate fee.
- Entrupy — subscription microscopy device + AI verdict. Designed for high-volume dealers.
- Beckett (BWS) — in-person watch authentication and grading service, mailed-in.
- Authorized-dealer authentication — Rolex AD, Patek AD, AP boutique inspections (limited and not always offered).
- Independent watchmakers — qualified individual watchmakers offering pre-purchase inspections by appointment.
WatchRadar — speed and breadth
Use case: pre-purchase inspection from a phone in two minutes, building a private watch box, issuing certificates for resale. Strengths: no hardware required, region-by-region inspection diagram, market-value estimate built into the dossier, public certificate verification page. Limits: visual-only (cannot see the movement), iPhone-only (Android in development), not yet recognised by most insurance underwriters as a sole verification chain. Best paired with a watchmaker inspection above USD 15,000.
Entrupy — hardware-mediated consistency
Use case: high-volume dealer authentication where photo-capture consistency across operators matters. Strengths: microscope hardware forces consistent magnification and lighting, established brand recognised by some underwriters, volume pricing for dealers. Limits: subscription cost has a meaningful floor, hardware ships and must be set up, not market-value aware. Comparable verdict accuracy to WatchRadar on modern luxury references; the differentiation is workflow, not accuracy.
Beckett — slow but ceremonial
Use case: pre-sale grading for auction or resale where a physical certificate from a recognised authority adds value. Strengths: in-person inspection by experienced graders, recognised in some auction contexts, physical certificate. Limits: turnaround time (weeks), shipping risk on the watch in transit, fee structure heavier than per-scan tools. Best for vintage pieces being prepared for major auctions.
Authorized dealer — limited but authoritative
Use case: confirming the watch with the brand directly. Reality: Rolex authorized dealers will not authenticate second-hand watches. Patek and AP have limited authentication services for high-value pieces but typically not for the secondary market. Where it works: AP's service centres can authenticate Royal Oaks during a service appointment; Patek's extract from the archives is the gold-standard paper evidence on vintage Patek. Wait times: weeks to months.
Independent watchmaker — the gold standard for movements
Use case: confirming the calibre, opening the case-back, inspecting movement engravings and finishing. Strengths: only option that goes inside the case. Eyes-on-movement diagnosis catches frankenwatches and swapped calibres that no visual-only tool can detect. Limits: requires the watch in the watchmaker's hands, scheduling, fee per inspection (USD 100–400 typical). Best paired with WatchRadar dossier as the visual evidence — the watchmaker confirms what is inside, the dossier documents what is outside.
