Due diligence

Authentication assistant

This never tells you a watch is genuine. It tells you exactly what to investigate before your money leaves the account.

Dial, caseback, clasp, rehaut, movement and paperwork. Photo review turns on once the backend is connected — the checklist below is what it returns.

Working example

Appears to be a Rolex Submariner Date 126610LN, 2022

Case, bezel insert and bracelet are consistent with the reference. The serial format is plausible for the stated year. Two photos are missing and one detail is inconsistent — see below. Send to a professional authenticator before resale: recommended.

Photos you still need

□Caseback straight-on, no glare
□Clasp interior with the code stamp
□Rehaut engraving at 6 o'clock
□Warranty card with the serial visible
□Movement, if the seller will open it

Details to inspect

□Serial matches the card and the case lug
□Lume tone consistent between hands, dial and bezel pip
□Crown logo depth and the crystal laser etch
□Bracelet end-link fit with no side gaps
□Date font and cyclops magnification

Known red flags for this family

□Super-clone movements with correct decoration
□Genuine case with an aftermarket dial
□Re-lumed hands on a service dial
□Papers from a different reference

Ask the seller

□Where and when did you buy it?
□Has it ever been serviced, and by whom?
□Are all bracelet links present?
□Will you accept escrow with a professional authentication window?
