Abstract

A watch for providing a digital time display comprises a movement mechanism disposed in a case that includes a number of continuous belts. The belts each have a numerical indicia consistent with hours, minutes and optionally second. The belts mounted over opposed drums, and the drums are rotated through gear engagement motors to move the belts. The arrangement of belts and drums are mounted on a frame separate from the case. The motors are operated to move the belts to cause the numerical indicia of the combined belts to register with one or more windows visible through a transparent cover to provide a time display. The belts may be oriented to overlap one another. The watch includes a microcontroller for controlling the operation of the motors, an optical sensor to determining the position of the belts, and a wirelessly rechargeable battery pack for powering the motors.

11. The portable timepiece as recited in claim 9 wherein the belts further comprise a third belt that includes numerical indicia for providing a second time display.

12. The portable timepiece as recited in claim 9 comprising four motors, wherein a first motor is operatively connected to a first belt having numerical indicia for providing a hour time display, wherein a second and a third motor are operatively connected to respective second and third belts having numerical indicia for together providing a minute time display, and wherein a fourth motor is operatively connected to a fourth belt having numerical indicia for providing a second time display.

13. The portable timepiece as recited in claim 1 further comprising an optical sensor for detecting the position of one or more belts.

14. The portable timepiece as recited in claim 1 wherein a substantial portion of the belts independent of the indicia providing the time display is visible through the front cover.

15. A timepiece for providing a digital time display comprising:

a case having a transparent front cover for viewing a time display;

a plurality of continuous belts rotatably disposed within the case, the belts comprising;

a first belt having a numerical indicia on its surface to provide an hour time display, and

a pair of second belts having numerical indicia on their surface to when combined provide a minute time display;

one or more windows positioned adjacent the belts to register with the indicia of the combined first and second belts to provide an hour and minute time display.

16. The timepiece as recited in claim 15 wherein the belts are each disposed between opposed respective drums, and the drums are rotatably mounted to a frame separate from the case.

17. The timepiece as recited in claim 16 further comprising one or more motors that are operatively coupled to the drums to move the belts to provide the time display.

18. The timepiece as recited in claim 17 wherein each belt is driven by its own motor.

19. The timepiece as recited in claim 17 comprising a microcontroller disposed within the case for controlling the operation of the motors to move of the belts to provide the time display.
