Authentication guide

Last reviewed June 2026

The Multifort Patrimony is a heritage reissue drawing on Mido's 1930s Multifort design. The movement is Mido Caliber 80 (ETA C07 with 80-hour power reserve), which is documented and serviceable. Authentication is straightforward for a current-production piece.

Known reproduction risks

toggle
LOW

Mido Multifort Patrimony is not a high-value target for reproduction.

Movement (Caliber 80)

Original: Mido-branded ETA C07 with 80-hour power reserve; Mido-signed rotor.

Replacement tells
  • A rotor without Mido branding suggests a movement swap or non-Mido service
  • A movement with less than 80-hour power reserve on a claimed Caliber 80 piece indicates either a different movement or a mainspring issue

Case back markings

toggle
2019 to present
  • "MIDO" and "MULTIFORT PATRIMONY" engraved or printed on caseback
  • "CALIBER 80" designation
  • "SWISS MADE"
  • Serial number
  • "WATER RESISTANT 100M" or similar

Movement tells

toggle
  • Caliber 80 power reserve can be verified: fully wind the watch, observe the running seconds, and confirm it runs for approximately 80 hours.
  • ETA C07 base is well-supported for service parts; any authorized Mido or Swatch Group service center can service it.
  • After service, power reserve indicator (if present) should reflect remaining reserve accurately.
