Embodiment Construction

[0017] The present invention will be described in detail below according to the accompanying drawings.

[0018] First, the main part and principle of the mechanism of this invention are demonstrated using FIGS. 1a-1d.

[0019] The mechanism for displaying the moon phases has a first or upper disc or moon phase disc 1, as shown in Figure 1a, in which two windows 1a and 1b are formed. Advantageously, these windows show the surface of the moon as a circular area on the opposite side of the surface of the disk 1 and at an equal distance from the center of the surface of the disk 1 .

[0020] The mechanism also includes a second or lower disc or moon phase indicator 2 depicted as an example in Figure 1b. According to the schematic illustration of FIG. 1 c , said moon phase indicator 2 is located concentrically on the underside of the moon phase disc 1 and will function as a background visible through the windows 1 a and 1 b in the moon phase disc 1 . Thus, on the surface turned t...

Abstract

Provided is the moon phase display mechanism to reflect the moon phase difference in vision between the northern and the southern hemisphere of the earth. This invention relates to the moon phase display mechanism that displays the moon phase.The moon phase mechanism consists of two discs ; the top disc (1) called moon dial and the bottom disc (2) called moon display part which are attached concentrically and rotatably each other. The moon dial (1) has two apertures (1a and 1b) so as to reflect the moon phase difference in vision between the northern and the southern hemisphere of the earth.

Description

technical field [0001] The present invention relates to a mechanism for displaying moon phases having an upper disc or moon phase disc and a lower disc or moon phase indicator, said lower disc being concentric with the upper disc, one of these discs are rotatably mounted relative to the other. Background technique [0002] This type of mechanism is suitable for use in a variety of specific devices, especially in complex watches, for example as one of the various auxiliary display devices in these watches. Displays of lunar phases generally reflect only one or a few aspects of the complex motion of the Moon relative to the Earth and the Sun that enable lunar phases to be observed from Earth. In particular, such conventional displays lack a true representation of the different appearance states or characteristics of the moon phases in the Earth's northern and southern hemispheres, or can only approximately correctly provide the moon phases in one hemisphere, but cannot truly ...
