Universal watch, has screens passing from position to another position under action of drive unit according to time of day, where unit provides torque or driving effort greater than that of friction unit connected to bearing structure

摘要

The watch (1) has a movement (10) directly or indirectly driving a secondary display unit (5) and a bearing structure (7) in synchronization with a main time display unit (2) e.g. hand co-operated with a complementary main time display unit (3) e.g. dial. The structure includes screens (8) superimposed to one of geographical reference marks (6). The screens pass from a position to another position under action of a drive unit (9) according to time of day. The drive unit provides torque or driving effort greater than that of friction unit (11) connected to the structure.
