Abstract
A watch includes a mechanical or electromechanical timepiece movement, analog time indicators, a lunar indicator indicating lunar date on a scale and driven by the timepiece movement to perform one revolution in one or two synodic months, and Chinese calendar indicator members actuated by a calendar mechanism driven from the lunar indicator. A month moving part provided with an indicator of lunar months is driven via a rocking lever so as to perform one revolution per ordinary year of twelve months and per leap year of thirteen months. The other Chinese calendar indicators are driven from the month moving part and comprise a first year indicator performing one revolution in twelve years, a second year indicator performing one revolution in ten years, and a third year indicator performing one revolution in nineteen years and associated with a cam representing the Chang cycle of ordinary years and leap years.
