The short version
WatchRadar is an iPhone-only app. You take five guided photos, the model returns a region-by-region dossier and a verdict in two minutes, and you can issue a public Authenticity Certificate. Free download, per-certificate fee. Designed for buyers, collectors, and resellers who want fast in-the-field authentication.
Entrupy is a subscription service that ships you a hardware device — typically a microscopic camera attachment for a phone — paired with their backend. You photograph specific points of the watch through the device; their model returns a verdict. Higher price point per scan, designed for high-volume luxury resellers and dealers who want a hardware-mediated verification chain.

Where WatchRadar wins
- Speed and setup. No hardware, no shipping, no subscription. iPhone in your pocket. Useful when you are at the seller's, deciding whether to commit.
- Region-by-region verdict. The inspection diagram pins each verdict element directly onto the photo of the watch, so you can see which tells were strong and which were weak. The conclusion is auditable.
- Market value built in. The dossier includes a fair-market band and an asking-price fairness verdict. Useful at the negotiation table — Entrupy gives you the authenticity verdict but does not tell you whether the price is reasonable.
- Provenance vault. Receipts, warranty cards, service log all attached to the dossier. The certificate references all of it. Useful for collectors building a chain of custody, useful for resellers selling the documented history rather than just the watch.
- No subscription floor. One-off buyers and collectors do not need a monthly subscription. Pay per certificate when you actually need one.
Where Entrupy wins
- Hardware-mediated photo capture. The microscope attachment forces consistent lighting and magnification across users — a high-volume reseller running many operators benefits from that consistency.
- Brand recognition with insurers. Entrupy has been around longer and is recognised by some insurance underwriters as a verification chain.
- Volume pricing for dealers. If you are running 200+ verifications per month, Entrupy's subscription math may be more favourable than per-certificate fees.
- Microscopic resolution. The hardware camera resolves details an iPhone camera does not — relevant on certain dial-print and case-engraving checks where resolution at the micron level matters.
When to use both
For high-volume luxury resellers, the cleanest workflow is to use WatchRadar at intake (fast triage on every consignment) and Entrupy at the high-value end (a second authentication chain for pieces above some price threshold). The two outputs are not redundant — they target different evidence — and presenting both alongside a piece is a stronger trust signal than either alone.
