ABSTRACT:
An ornamental clock with decorative time indicator, wherein the hour, minute and second indicator rotating shafts are elongated and can steadily rotate without swinging, characterized in that the elongated rotating shafts can accurately and co-axially and point-to-point rotatably contact with one another so that friction therebetween can be reduced to a minimum and they can be steadily driven by their corresponding indicator connectors without swinging movement, the second indicator being of global shape and the minute and hour indicator being two transparent or perforated spheres whereby when they relatively rotate at different speeds, the time is accurately indicated and excellent decorative effect is created.
