WATERTIGHT WATCHCASE FOR WRISTWATCHES

摘要

An internal capsule constituted by a vessel made of a soft plastic material and by the watchglass is kept closed by an external capsule constituted by two metallic pieces fixed onto one another by screws. These pieces press the glass axially on the upper edge of the lateral portion of the plastic vessel so as to form a tight seal therebetween. The watch movement is held in place within the internal capsule by clamping. The lateral portion of the plastic vessel is therefore transversely compressed between the movement and one of the metallic pieces of the outer capsule.
