To provide a mechanism intended to cause tips of flexible pointers to trace two mutually different paths.SOLUTION: A flexible pointer has a first cannon 166A and a second cannon 166B connected to a tip of the flexible pointer via a flexible arm, and changes an angle position of the second cannon 166B relative to the first cannon 166A to change its shape and length to a desired shape and length. Each flexible arm of the flexible pointer makes an angular rotation θ1 that a disc of a watch movement applies to an operation mechanism 160, where the angular rotation θ1 applied by the disc of the watch movement is adjusted with an additional angle φ(θ1/2) by the operation mechanism 160, and the additional angle φ(θ1/2) is applied in opposite directions to two flexible arms of the flexible pointer, to determine the change of the shape and length of the flexible pointer over two direct successive revolutions so that the tip makes two non-identical successive complete revolutions.SELECTED DRAWING: Figure 8A 【課題】可撓性指針の先端が２つの互いに異なる経路を描くようにすることを意図した機構を提供する。【解決手段】可撓性指針は、可撓性アームを介して可撓性指針の先端に接続された第１のキャノン１６６Ａおよび第２のキャノン１６６Ｂを有し、第２のキャノン１６６Ｂの角度位置を第１のキャノン１６６Ａに対して変化させて所望の形状および長さに変化させ、可撓性指針の各々の可撓性アームは、時計ムーブメントのディスクが作動機構１６０に適用する角回転θ１を行い、時計ムーブメントのディスクによって適用された角回転θ１は、作動機構１６０によって追加角度φ（θ１／２）で調整され、この追加角度φ（θ１／２）は、可撓性指針の２つの可撓性アームに逆方向に適用され、先端が２つの同一ではない連続する完全な回転を行うように、直接連続する２回転にわたって可撓性指針の形状および長さの変化を決定する。【選択図】図８Ａ
