ABSTRACT:
A timepiece includes a main plate and gear train bridge with a center wheel and pinion supported therebetween by one or more bearing members integrally formed in the main plate and gear train bridge. A plurality of springs integrally formed in said plate and bridge are used for positioning internal members of the timepiece relative to each other. Additional similar springs are used for fixing the frame structure to the casing of the timepiece. A pressing plate can be connected to the main plate and includes one or more leaf springs for fixing a back cover of the timepiece away from the frame structure. One or more of the plates or bridge can be electrically conductive for delivery of current to an internal member.
