The invention relates to a clock, which comprises hands consisting of an hour hand, a minute hand and a second hand; the hands are provided with a gear transmission mechanism; the gear transmission mechanism comprises at least one relatively fixed gear and at least one movable gear; the relatively fixed gear is arranged on the minute hand; the movable gears are connected to the second hand and/or the hour hand by virtue of connecting elements; during walking, the movable gears do rotation movement while doing revolution movement around the relatively fixed gear; the relatively fixed gear can be fixedly connected to the minute hand, or can be integrally formed with the minute hand through injection moulding; the movable gears can be symmetrically or asymmetrically distributed on the second hand and/or the hour hand. According to the clock disclosed by the invention, the new gear transmission mechanism is added to the hands, so that the clock has more additional functions; the minute hand does not shake while walking due to the meshing resistance of the added gears on the second hand and the hour hand; more fashionable and dynamic elements are added to the clock, so the clock has the advantages of being novel in structure, dynamic and fashionable.
