Abstract

PURPOSE: To enable the slug of press blanking to be easily removed in a body having bayonet construction, by joining a body disposed with bayonet projections and separate bodies divided by the cavity part at the top surface of this projection thereby producing the body.

After this, separate bodies 2 divided at the cavity part 1-b at the top surface of the bayonet projections are joined, whereby the watch-case is produced.
