Authentication
The open-heart F7M62 movement and moonphase/power-reserve dial layout are distinctive enough that misrepresentation, not counterfeiting, is the practical risk; confirm the reference matches the dial color shown, since Orient Star sold this design in black, white, and blue mother-of-pearl.
Known issues in the market
- The RE-AY0107N ships with a textured black dial; white and blue mother-of-pearl dial variants exist under different reference numbers in the same Classic collection, and listings sometimes conflate them.
- The open-heart aperture exposes the balance and regulation; any inconsistency in decoration quality there compared to official photos suggests a different grade or a serviced movement with non-Orient parts.
- The moonphase disc is crown-adjustable; confirm it advances correctly rather than being manually set only via full disassembly.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| movement | Cal. F7M62 open-heart decoration | Open-heart aperture shows the balance wheel and regulation with consistent finishing quality matching official product photos | Aperture is blocked, mismatched, or shows visibly different finishing from reference photos |
| dial | Dial color matches stated reference | RE-AY0107N has a textured black dial with applied Roman numerals; other Classic references have white or blue mother-of-pearl dials | Dial color does not match the stated reference number |
| movement | Power reserve indicator and moonphase function | Power reserve indicator under 12 o'clock reads consistently with winding state; moonphase disc above 6 o'clock advances correctly | Power reserve indicator stuck or erratic; moonphase disc not advancing |
| caseback | Sapphire display caseback | Sapphire crystal caseback with a clear view of the movement and Orient Star markings | Solid caseback or unclear/scratched crystal inconsistent with a display-back model |
Common legitimate replacements
- Strap; factory patent leather is glossy black, commonly swapped for a matte alternative.
- Crystal; sapphire is standard front and back.
