Where Copies Differ

  • Movement finish. The genuine calibre shows striped bridges, polished bevels, and an engraved rotor. Copies show tool marks and printed rotor text.
  • Calendar change. The genuine calendar advances near midnight. Many copies drag through the change over several hours.
  • Moon phase. The genuine moon phase steps once per lunar day of 24 hours 50 minutes. Copies jump a full 24 hours.
  • Apertures. Day, month, and moon phase windows sit flush on the genuine dial. Copies show uneven gaps and off-center discs.
  • Case back. Genuine uses sapphire with engraved reference and serial numbers. Copies print text in the wrong font.
  • Case profile. Copies run thicker and heavier than the genuine case.

Checks Before You Buy

  1. Ask for a photo of the movement through the case back.
  2. Match the case back serial to the warranty card and service papers.
  3. Watch the calendar change at midnight. Film it.
  4. Compare the date hand shape with photos from Blancpain.
  5. Send the serial to a Blancpain service center for verification.

Serial checks are the only reliable test. Photos of a dial cannot confirm a movement. If the seller refuses a case back photo, the item is unknown. Treat it as a copy.

Resale and Service

A copy has no resale market and no service path. Blancpain will not service or authenticate a counterfeit. Independent watchmakers can replace a third-party movement, but parts for the calendar module are not standardized between factories. Two copies of the same reference can hold different movements.
