Abstract (en)
[origin: US4440505A] The watch case comprises, notably, a case band 1, a crystal 14 and a back 5 detachably mounted on the case band and a caging ring 6 assuring the positioning of a movement 22 in the case. The case band 1 has an upper opening 2 designed to be sealed by the crystal and a smaller-sized lower opening 3 defined by a projection 7 radially extending inward to its lower part. The caging ring 6 has an upper portion 10 and a lower portion 11 containing outer surfaces 12, 13, the dimensions of which correspond respectively to those of the upper opening 2 and lower opening 3 of the case band 1, the ring 6 being insertable in the latter through its upper opening before mounting of the crystal and placed so that its lower portion 11 is engaged in the lower opening 3 of the case band 1. The back 5 is held against the lower surface 8 of the projection 7 of the case band by means of set screws 9, tightening of which assures the locking of the caging ring 6 in the case.
