Aeternitas Mega Grande Complications

All the Megas feature a base automatic movement, which has a tourbillon at 6 o’clock, grande and petite sonneries, minute repeater, and Westminster carillon. The Aeternitas Mega comes in four versions with increased complexity. Inside Information: The eternal calendar of the Franck Muller Watchland workshops is different from any traditional perpetual calendar in that it takes into account the rule governing the Gregorian calendar, which states that all century years not divisible by 400 are common years and not leap years. The eternal calendar follows a cycle of 1,000 years thanks to two additional sets of wheels.
