Watch making mechanism for indicating different lunation phases, has lunar phases representing marks integrated with lunar phase disk, and apertures permitting observation of marks across dial

摘要

The mechanism has lunar phases representing marks (1) integrated with lunar phase disk (2), and apertures (3) permitting the observation of the marks across a dial. The marks can be presented under different aspects such as color, sign, number, letter or abbreviation for indicating specific phases of lunation. The marks are visible across the apertures only when the marks indicate lunation phases.
