Abstract: The navigation device includes a compass module including a base, a permanent dipolar magnet mounted for rotation relative to the base so that the magnet tends to align with the earth's magnetic north, a disc having a display fixed with respect to the magnet, and a transparent cover fixed to the base and arranged over the display surface. The display surface has map indicia for a pre-determined geographic area, map indicia being oriented to define a direction of magnetic north with respect to the map indicia, the indicia being aligned with respect to magnet so that the direction of magnetic north with respect to the map indicia coincides with earth's magnetic north when the magnet is aligned with earth's magnetic north. The compass module is fixed in a housing having a slot from which a folded map of the pre-determined area can be withdrawn, one end of the map remaining fixed to the housing.

Abstract: A timepiece includes a plurality of coaxially mounted disks which are driven with different periods, at least some of the disks having a time indicator area which is visible through one or more transmissive areas on one or more disks which lie over it. In a preferred embodiment, one of the disks is provided with three concentric annular zones and is driven with a period of sixty seconds. The outermost zone has discrete reflective areas which are visible through discrete transmissive areas in an overlying annular zone. The inner zones have discrete transmissive areas through which discrete reflective areas in two concentric annular zones on two respective lower disks are visible. The lowermost disk is driven with a period of twelve hours and is visible through a central transparent area of an intermediate disk which is driven with a period of sixty minutes.
