Abstract

The present invention provides a wristwatch structure, an electronic crown for wristwatch, and a wristwatch having a display. The wristwatch structure comprises an electric driving component; an electronic core having a plurality of two-dimensional joints; and an electronic crown comprising a rotating portion and a fixed detecting portion, the detecting portion detecting electronic signals according to a rotation of the rotating portion; wherein the detecting portion of the electronic crown exports the electronic signals to the electronic core via one of the joints, and the electric driving component is electrically connected to one set of joints among the two-dimensional joints. The present invention can improve compatibility for various designs, thereby shortening product development cycle. Also, the present invention is suitable for developing a product with appearance similar to a mechanical watch.
