A side surface of one of the movement 2 and the groove 7 has at least one elastic projection 8, and a side surface of the other of the movement 2 and the groove 7 has recesses 9 fitting the elastic projections 8.

[0021] According to one example of the present disclosure, the projections and the recesses are disposed at dual points, that is, at the positions of 6 o'clock and 12 o'clock of the case or the movement respectively. According to other examples, the projections and the recesses are disposed at four points, that is, at the positions of 2 o'clock, 4 o'clock, 8 o'clock, and 10 o'clock of the case or the movement respectively.

[0022] As shown in FIG. 3, the side surface of the groove 7 of the case 1 has a protruding elastic projection 8, and the side surface of the movement 2 has a recess 9 fitting the elastic projection. Of course, the elastic projection 8 may also be disposed on the side surface of the movement 2, while the recess 9 is located in the side surface of the groove 7 of the case 1 correspondingly. Alternatively, as shown in FIG. 4, the side surface of the groove 7 of the case 1 and the side surface of the movement 2 each have an elastic projection 8 and a recess 9 for alternate fitting.

[0023] The shape, number, position and material of the elastic projections 8 and the recesses 9 are not limited. As shown in FIG. 1, according to this example, a crown holding slot 5 for holding the crown 4 is provided in the case 1.Example 2:

[0024] The detachable structure is a buckle structure which is removable by pressing.

[0025] According to the detachable structure, the movement 2 and the case 1 are in buckled fit. A buckle is disposed on a liner of the movement. The buckle may also be disposed on an inner wall of the case. The buckle structure is achieved by means of pressable elastic members.

[0026] According to one example of the present disclosure, raised elastic members are disposed on the movement. The raised elastic members may be pressed and deformed via connecting buttons on the movement. Recesses are provided in the case to clamp the raised elastic members, and the raised elastic members may be moved into or out of the recesses in the case by pressing the connecting buttons, thus achieving assembly or disassembly of the movement and the case.

[0027] According to other examples of the present disclosure, the raised elastic members may also be disposed on the case, and the recesses may be provided in the movement.

[0028] Further preferably, the recesses may also be provided as elastic structures, and the raised elastic members in the recesses may be pushed out by pressing.

[0029] According to other examples of the present disclosure, the raised elastic members and the recesses are disposed at dual points, that is, at the positions of 6 o'clock and 12 o'clock of the case or the movement respectively.
