Abstract (en)
[origin: WO9711412A1] A clock, known as a "mystery" clock as it is almost entirely transparent, is disclosed. The clock comprises a transparent dial with reading indicia (11), a minute indicator that is transparent except in the region of a clock hand (28'), and an hour indicator that is also transparent except in the region of a clock hand (26'). The indicators and the dial have a common axis (Y) and are supported by a frame or rim (20), and the indicators and/or the dial have peripheral teeth concealed behind said rim (20) for rotating the indicators and the dial relative to the rim (20) about said axis (Y). Said clock further comprises a fixed frame (2) having a fixed axis (X) and movably supporting said rim (20); first drive means (19, 18') for rotating said rim (20) and the indicators and dial thereon about said fixed axis (X) in a predetermined direction and at a predetermined angular speed; and second drive means (17, 22) responsive to the rotation of the rim (20) for rotating said dial and/or said minute indicator and/or said hour indicator about said axis (Y) by engaging the circumference thereof to cause relative rotation of said indicators and said dial and thus provide an instant indication of the time by means of the relative angular positions of said indicators with respect to the dial.
