Key Features & Design Elements

  • Top sub-dial: Date indicator (1–31)

  • Left sub-dial: Day of the week indicator

Authenticity Indicator Cartier does not produce an authentic model with this specific combination of dial colors, layout, and sub-dial functions. Standard Cartier multifunction/calendar complications use distinct, highly refined layouts (such as retrograde displays or simple moonphase indicators) rather than this standard generic 3-subdial setup.
