MING 17.09 moonphase; inspect moonphase display accuracy and dial construction.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| dial | Moonphase display quality | Moonphase aperture clean with crisp moon disc, no scratches on the lunar display, stars visible and correctly placed | Scratched or damaged moon disc, lunar display that appears dirty or has debris behind the aperture |
| caseback | 17.09 designation and serial | MING 17.09 moonphase designation, serial verifiable with community databases | Wrong designation, unverifiable serial |
| movement | Movement with moonphase module | Moonphase module visible and consistent with MING 17.09 specification | Movement that lacks moonphase module, movement swap evidence |
Ming 17.09 adds a moonphase complication to the 39mm case. Moonphase disc accuracy and applied index consistency are the combined authentication checks.
