Embodiment Construction

[0022] usually, figure 1 The wrist watch 20 shown comprises, on its top face, a dial 21 associated with a plurality of rotating indicator elements, such as hands or dials, which rotate relative to corresponding scales provided on the dial 21 . These indicator parts are driven by the timepiece movement of the mechanical or electromechanical watch 20 . The watch comprises the customary control parts of a calendar watch, in particular a control stem with an external crown 22 and means for correcting the calendar. In the example above, all indicator components turn clockwise.

[0023] The display part firstly comprises a time, hour analog display with hour hand 24 and minute hand 25 , for which scale 26 is the usual hour circle. Obviously, a second hand could also be set, but it doesn't exist in this example.

[0024] The indicators of moon phase and age include a moon disc 27 which normally completes a half revolution each synodic month. The disc 27 is visible in a specially...

Abstract

The invention relates to a watch comprising: a mechanical or electromechanical clockwork movement, analogue time indicators (24, 25), a moon indicator (27) which displays the lunar date on a scale (31) and which is driven by the clockwork movement in order to complete one revolution over one or two synodic lunations, and Chinese calendar indicators which are actuated by a calendar mechanism (50) that is driven by the moon indicator (27). According to the invention, a month mobile (70), which is provided with a lunar month indicator (34), is driven by means of a lever (60) such as to complete one revolution for every common year of twelve months and for every leap year of thirteen months. The other Chinese calendar indicators are driven by the month mobile and comprise a first year indicator (40) which completes one revolution every twelve years, a second year indicator (44) which completes one revolution every ten years and a third year indicator (37) which completes one revolution every nineteen years and which is associated with a cam (63) that represents the Chang cycle of common years and leap years. The inventive watch can also comprise a perpetual Julian calendar.

Description

technical field [0001] The invention relates to a timepiece comprising a timepiece movement, a time indicator part, a month indicator part driven by the timepiece movement and making one revolution during an integer number of synodic months, a calendar indicator part movable relative to a dial, And the calendar mechanism driven from the timepiece movement. Background technique [0002] Calendar watches are usually set to indicate values ​​according to the Gregorian calendar, more specifically the Julian or Gregorian calendar. The calendar mechanism is essentially set up to count the days of each month, and when applied to count months, increments the year counter every twelve months. Therefore, this mechanism is only actuated once a day by the timepiece movement with the wheel driven by the hour wheel at a ratio of 1:2. [0003] The present invention proposes to incorporate a calendar indicator component for a traditional lunar calendar into a timepiece. Currently, the lu...
