Abstract (en)
[origin: US4589886A] In the manufacture of a watch case part comprising a glass and a middle having an opening for the glass, the following operations are carried out: first, a metallic coating is deposited on a peripheral portion of the glass, then one or more elements are formed on the coating by moulding a molten material having an affinity for the metal forming the coating, whereupon the glass is secured to the middle through the intermediary of the fastening element. The fastening element may consist of a heel extending around the periphery of the glass or of fastening studs extending at right angles to the plane of the glass. In some cases the fastening element may also act as sealing element.
