ABSTRACT:
A watch middle cum plate is described that comprises an annular middle-forming portion and a plate-forming portion which is surrounded by the middle-forming portion and which is formed with recesses for receiving components of the watch movement. The middle cum plate is provided with a protective coating of which a first part essentially covers the plate-forming portion and of which a second, thicker, more resistant part covers at least the visible surfaces of the middle-forming portion.
Such middles cum plates may be made from flat brass blanks by machining recesses in their central portion for receiving components of a watch movement, by applying to the blanks a layer of material that is chemically more inert than brass to form the first part of the above coating, stacking and assembling the blanks such that at least the above central portions of the blanks with the recesses are masked, and applying to the visible regions of the stacked and assembled blanks the above second part of the coating.
