A tidal information display device for a movable body includes a position measurement module configured to detect a position of the movable body, a geographical information selection module configured to determine geographic information to be displayed on a display screen based on the detected position, a tidal information module configured to receive and store tidal information based on the detected position, and a tidal information display module configured to generate display data for displaying a graphical user interface (GUI) at a predetermined position on the display screen. The GUI is configured for showing the tidal information including at least one of: a present height of a tide, a high tide time, a low tide time, and a position of the tide.

A moon phase display mechanism driven by a horological movement, this moon phase display mechanism including a transparent support provided with an upper face and a lower face which extends at a distance from the upper face, a representation of the Moon being transferred, for example by printing or by engraving, to one of the upper or lower faces of this transparent support, a substrate being disposed under the transparent support, at a distance therefrom, the moon phase display mechanism also including a shutter which is driven by drive means moved by the horological movement and which is arranged so as to displace between the transparent support and the substrate, the shutter and the substrate having display contrasts which are inverted relative to each other.

The present invention proposes a timepiece mechanism comprising: a lever, rotatable about a lever axis, the angular position of the lever representing a first value, wherein a zero value of the first value corresponds to a reference direction, a sliding block mounted to move in translation on the lever in a direction substantially perpendicular to the axis of the lever and comprising a guide-mark element whose trajectory in translation relative to the lever is secant to the lever axis, the radial position of the guide-mark element with respect to the lever axis representing a second value, an output device formed of a deformable parallelogram in a plane perpendicular to the lever axis, the parallelogram including a first side, which is stationary with reference to the lever axis and perpendicular to the reference direction, a second side, which is opposite to the first side and linked in translation to the guide-mark element in the direction perpendicular to the reference direction,
the angular position of the third and fourth sides of the parallelogram, which are adjacent to the first side, being substantially proportional to the product of the first and second values.

A tidal clock includes a clock face, a clock mechanism, a tidal display mechanism, a tidal drive arrangement and one or more symbolic display members. The tidal display mechanism includes a background and a plurality of laminar members overlying the background. Each laminar member includes a display representing sea and having an upper edge configured to represent a sea level. The laminar members are independently movable between respective lower and upper positions to represent rise and fall of the sea level. The symbolic display members are each mounted on a respective support. Each support is engaged with the background, permitting movement between lower and upper positions, further engaging a respective laminar member and arranged so that the support and display mounted thereon is urged to move between lower and upper positions by the corresponding movement of the laminar member.
