[origin: EP1868049A1] The timepiece has a control wheel (32) engaged with a setting wheel (38) which is connected in rotation with a driving wheel (40) executing a rotation in twenty-four hours. One lunar month corresponds to a number of steps of a toothed disk (22). The wheel (32) executes a rotation in 30th disk step of lunar month. Gear ratio between the wheels (32, 38) is equal to 1.015895953757230. The wheels (32, 38) has 692 and 703 teeth, respectively, and are made of crystalline material e.g. single-crystal silicon and polycrystalline silicon, and electroformed metal.
