PROBLEM TO BE SOLVED: To solve the problems wherein, in a timepiece having a plurality of retrograde displays, a structure using a distribution wheel has a large occupied area portion, and poor flexibility for arranging a display mechanism, and a wheel having a retrograde display has large backlash in its structure to thereby hardly stabilize a hand indication position, and to require an arrangement space for a countermeasure mechanism, and further, a return lever using a conventional technology has a large rotation angle in its structure, a large occupation space, a large bending amount, high material cost and processing cost, or the like. SOLUTION: A plurality of retrograde displays are performed in a structure not using the distribution wheel, and a plurality of return levers for removing backlash are piled or a return lever and a flyback lever are piled together, to thereby secure a domain for a plurality of levers with an area for one lever portion. Further, by changing spring arrangement of the return lever, a using space of the lever is reduced, and cost can be improved. Arrangement flexibility of the retrograde displays can be enlarged greatly by this structure. COPYRIGHT: (C)2009,JPO&INPIT
