Embodiment Construction

[0022] In general, the watch 20 shown in FIG. 1 includes 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 moon phase and moon age indicators typically include a moon disc 27 which completes a half revolution each synodic month. The disc 27 is visible in a specially sh...

Abstract

The wristwatch disclosed in the present invention comprises a mechanical or electromechanical timepiece movement, an analog time indicator (24, 25), indicating the lunar date on a scale (31) and is driven by the timepiece movement to rotate one or two lunar months A circular lunar indicator (27), and a lunar indicator component actuated by a calendar mechanism (50) driven from the lunar indicator (27). The month moving part (70) with the lunar month indicator (34) is driven via the rocker (60) so as to make one revolution every common year with 12 months and every leap year with 13 months. Other lunar indicators are driven from the month movement and include a first year indicator (40) with a 12-year rotation, a second year indicator (44) with a 10-year rotation, and a 19-year rotation And a third year indicator (37) associated with a long period cam (63) representing normal and leap years. The watch can also include a Julian perpetual 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...
