A timepiece includes a base, a case, a frame, and a gimbal coupling mechanism. The case holds a time display. The case is pivotably connected to the frame for rotation about a first axis. The frame is pivotably connected to the base for rotation about a second axis between an extended and a retracted position. The frame form a two-axis gimbal supporting the case. The gimbal coupling mechanism operably couples the frame and the case whereby rotation of the frame from the retracted position to the extended position then back to the retracted position rotates the case about the first axis to facilitate flipping of the case so as to selectively hide or show the time display.

A wristwatch is described, including a middle having a side wall, defining a median plane and further having attachment members for securing respective first and second ends of a strap to the middle, and a cover capable of pivoting, relative to the middle, between a first closed position in which the ends of the strap are locked onto the middle, and a second open position in which the ends of the strap are free to be separated from the middle. The cover is arranged so as pivot about a rotational axis parallel to the median plane, each attachment member including a hole provided in the side wall and intended for receiving the corresponding end of the strap by insertion in a direction substantially parallel to the median plane.

A convertible smart watch including: a frame having a groove; a watch body having an analog watch unit on one side and a smart watch unit on the other side leaning against each back, which is designed to be inserted to the groove; and a supporting member supporting the watch body so as to be rotatable, wherein one side is combined to the frame with a hinge such that watch body may rotate with respect to the frame between a first position being inserted to the groove and a second position being protruded to the front of the frame by leaving from the receiving groove.
