Abstract
A watch casing has a back and a body or middle part made in one piece, and a glass engaged in the middle part. A strap is provided with an annular central portion bearing on the glass and with diametral arms secured to hinge lugs of the casing serving for the attachment of the bracelet. Thus, the glass is retained in place even when it is only engaged frictionally in a sealing gasket located in the casing body. The removal of the glass can be effected easily by engaging a blade into a lip of the casing body and into an annular groove provided for this purpose in the lateral face of the glass.
