To provide a duplicate effect compensation tool for attaching clock hands which makes visual control of both of maximum force and minimum force possible and can exactly adjust force strength.

A stake 17 screwed in a lower side rod 11 is provided at one end of a tool and an upper tube 15 where a head 18 is screwed in to be able to add force F is provided at the other end. The lower side rod 11 pushes a spring 33 pressing to the first tension control means 43 and, overlapping so that a motion indication member screwed in a tapped hole 34a for the first force F1 can be confirmed, and slides inside a tube part 13a of a middle cylinder element 13. The middle cylinder element 13 itself pushes the second spring 35 pressing to the second tension control means 45 and, overlapping so that a motion indication member screwed in a tapped hole 36a for the second force F2 can be confirmed, and slides inside the upper tube 15.
