Authenticating a luxury watch requires experience, precision, and meticulous attention to detail. At The Swiss Link, every watch is subjected to a thorough, multi-stage authentication process carried out by experienced specialists.
From visual inspection and movement analysis to documentation and provenance checks, our process ensures that each watch we handle is genuine, correctly represented, and meets the highest standards of authenticity.
Each watch is received and logged into our system with high-resolution photographs from all relevant angles. All accessories (boxes, warranty cards, manuals, links, original tags, etc.) are catalogued as part of the intake.
Our specialists inspect the case for signs of polish, any dents, scratches, or previous repairs. Engravings, hallmarks, and manufacturer stamps are compared to official references for authenticity.
The bracelet and clasp are examined for correct reference numbers, logos, and construction. Links, end pieces, and clasps are checked for manufacturer authenticity—no aftermarket or replacement parts. Wear patterns and flexibility are inspected to ensure condition matches age and type.
Dials are examined under magnification for correct lume, printing, logo placement, and finish. We check for repainted, refinished, or aftermarket dials and hands. Originality and period-correctness are verified.
All crowns, pushers, bezels, and crystals are examined for authenticity and fit. Manufacturer logos and markings are checked on all external parts.
Case back is opened by professionals to access the movement, always using non-invasive tools. The movement is inspected for authentic manufacturer markings, correct calibre, and absence of corrosion or unauthorised repairs. Match movement serial/reference numbers to the watch case and official records.
Full functional check: Time, date, day, chronograph, GMT function, and any complications. Checked for smoothness and accuracy using timing machines. Water-resistance is tested according to manufacturer recommendations (if applicable).
Warranty cards/papers are checked for authenticity, matched to the watch by serial/reference. Sales receipts, service papers, and any provenance documentation are reviewed for consistency and legitimacy. Original instruction booklets and manuals confirmed correct for model and year.
Boxes, booklets, hang tags, bezels, extra straps/bracelets, and other included items are confirmed authentic and correct for the watch reference. Accessories are photographed and catalogued as part of the official listing.
A second in-house expert verifies all inspection points. Any discrepancies are flagged for further review or clarification before authentication is finalised.
Upon passing all checks, a certificate of authenticity is issued and included with the watch. Watch and all included accessories are securely packaged, insured, and shipped with full tracking.
