Abstract

PURPOSE: To eliminate the gap caused at the crown part by applying the force via the spring to pull the crown inward, thus ensuring the easy prevention for the dust and sweat.
CONSTITUTION: The center-ward force is applied to setting stem 43 via setting lever guard 48 which engages to pin 7 to secure a close adhesion for surface 42a of crown 42 to setting stem pipe 49. Thus the gap is eliminated between pipe 49 and crown 42 to prevent intrusion of the dust and sweat. In the case of case 1 using no pipe 49, surface 42a is adhered close to case 1. In addition, the packing of the rubber or the like is provided to surface 42a or 42b to enhance the effect desired. The mechanism to pull crown 42 toward the center can also be formed by the spring or the like in place of the setting lever. In such simple constitution, the preventing mechanism can be realized for the dust and sweat.
