Community + OSINT signals haven’t landed for this reference yet. We don’t publish a rating against zero signal: the number would mean nothing. Editorial body + caliber + market value still surface above; ratings appear once the signal corpus does.
Sinn is not a meaningful counterfeit target, and the 104 is one of its most straightforward watches. The checks worth doing are about the movement and the bezel, not about the watch being genuine.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| case | Bezel rotation | Turns in both directions with a defined click through the full rotation | Rotation in one direction only, or a bezel that turns freely with no click |
| movement | Caliber SW220-1 day and date quickset | Both day and date advance independently from the crown and change fully at midnight | Either indication failing to quickset, or a changeover spread over more than a few minutes |
| dial | Metallic green surface and printing | Even metallic green across the dial with crisp white printing and no bleed at the edges | Blotchy or dulled areas, which on a watch this recent usually means moisture ingress |
| crown | Screw-down crown and 200m seal | Crown threads cleanly and seats fully; the 20 bar rating depends on it | Cross-threading or a crown that will not seat, which is both a fault and a water-ingress risk |
