Abstract
The time indicator has a central disc (122) connected to the watch movement (112) so as to make one revolution during a 24 hour period. The disc supports a projecting hemisphere which represents a terrestrial globe having its axis of rotation passing through a pole. A rigid elastically deformed wire (128) extending longitudinally forms a meridan. The wire is driven by a control unit (130) so as to display the frontier between an illuminated time zone (132) and a non-illuminated zone (134) of the earth. ADVANTAGE - Display of illuminated and non-illuminated zones is precise yet miniaturised so that it can be incorporated in pocket or wrist watches.
