ABSTRACT:
The wrist watch of this invention includes a caseband (18) and a baseplate (20) formed as a single piece to give a baseplate-caseband (10). The baseplate-caseband is entirely coated by a thin protective layer (60) of substantially constant thickness. In order to protect the portions of the caseband exposed to exterior stresses (shocks etc.) the baseplate-casband is borne by two longitudinal struts (1) fastened on either side of the caseband. These struts are provided in a manner such that they exhibit a greater resistance to said exterior stresses than does the baseplate-caseband. In particular the longitudinal struts (1) are coated with a protective layer (61) of greater thickness than the layer (60) which coats the baseplate-caseband.
