Authentication
A 10-piece platinum tourbillon with a hand-decorated Urushi lacquer and maki-e dial. As with every Credor flagship, counterfeits essentially do not exist; the real risk is misrepresentation of a lower Credor grade as this piece, or overstating the dial's decorative technique.
Known issues in the market
- The dial combines Urushi lacquer, mother-of-pearl (raden) inlay, gold-powder maki-e, and kirikane gold-leaf cutting; each is a distinct hand-applied technique and a genuine example should show visible depth and texture from all of them, not a flat printed approximation.
- The flying tourbillon bridge is openworked and should be visible from the dial side; a covered or partially obscured tourbillon is inconsistent with this model.
- Only 10 pieces were made; any example should have documented provenance given the tiny production run.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| dial | Urushi, raden, and maki-e dial technique | Visible depth and texture from lacquer, mother-of-pearl inlay, and gold-powder decoration; the bird motif has dimensional relief rather than a flat printed look | Flat, uniformly glossy dial with no visible texture or relief under magnification |
| movement | Calibre 6850 flying tourbillon | Openworked flying tourbillon bridge visible from the dial side, rotating smoothly once per minute | Tourbillon obscured, stopped, or rotating at an inconsistent rate |
| case | Platinum case weight and marks | Platinum (950) case with correct hallmarks; noticeably heavier than a white gold case of the same dimensions | Case weight inconsistent with platinum; missing or incorrect purity marks |
Common legitimate replacements
- Strap; Credor OEM leather preferred to preserve the piece's presentation.
Expert resources: Seiko/Credor boutiques in Japan can verify via serial number given the 10-piece run. Monochrome Watches' introduction coverage documents the dial technique in detail for comparison.
