Abstract
The invention relates to a base element for a wristwatch and in particular a base element in the form of a laminate composed of two plates and a plastic foil. According to the invention, spacer elements, in particular in the form of a non-woven fiber fleece, are embedded in the plastic foil. This will avoid the plastics material being squeezed out laterally along the edges of openings and the like during heat-sealing of the plates with the plastic foil and, at the same time, a high degree of accuracy regarding the thickness of the finished base element will be achieved.
