A case including a first case which has a retaining portion provided on an outer circumference thereof, an exterior member which has an engaging portion with which the retaining portion is engaged, and covers the outer circumference of the first case, a second case which is arranged on upper parts of the first case and the exterior member, and a fastening member which attaches the second case to the first case by fastening the second case to the exterior member.

A watch is a watch including a watch case, a cover glass attached to the watch case, and a decorative body attached to the watch case, wherein the watch case includes a holding wall portion provided along an outer periphery of the cover glass, a first column portion provided outside the holding wall portion, a second column portion provided outside the holding wall portion, and provided at a distance from the first column portion, and an inclined portion including an inner end portion formed from between the first and second column portions to the holding wall portion, and is connected with the holding wall portion, and an outer end portion is connected with an outer surface of the watch case and provided at a position close to a rear surface of the watch case, and the decorative body is held by the holding wall portion, the first, and second column portions.

Watch case (1) having a middle (2) provided with a blind hole (20); a first mobile horn (3) for fastening a strand of a bracelet, and provided with a through-hole (33); a first elastic element (31) exerting a force on the horn (3) that tends to push it back into a position with a widened lug distance (d); a push-button (5) traversing said through-hole (33) and engaged in the blind hole (20) in the middle, arranged so as to be able to slide between a locked position, in which the push-button (5) blocks the displacement of the horn (3), and a released position in which the displacement of the horn (3) into pushed-back position is possible, a second elastic element (52) exerting a force on the push-button (5) to push it hack into the locked position.

A case configured to receive a plurality of mechanical watch movements in the wound state, each movement being housed inside a compartment, configured to receive and maintain the movement according to a predefined orientation. In this position, the winding buttons of the movements are positioned facing respective microphones which are mounted inside the case. The microphones are configured such that they cancel the noises detected, such that the acoustic measurements of each of the movements are essentially not disturbed by the noises produced by the adjacent movements. Also, a method for testing a plurality of mechanical movements installed in the case, and to a testing system which includes the case. The movements are measured by a plurality of cycles of consecutive and successive measurement periods.
