摘要

The mechanism has a watch movement including an hour wheel (28), a wheel (30) for phases of the moon and a mobile (32) for stages of tides kinematically linked to the hour wheel and designed to bear units displaying phases and tides of the moon. The mobile for stages of the tides is kinematically linked to the wheel hour through the wheel for the phases of the moon. A scale with graduations is provided in the mechanism, where a step between two gradations represents one hour.
