Work plate (clock)
In small watches, a work plate or plate (also known as platina ) is the thin and flat part of a movement on which the components such as wheels , drives , bridges , cocks , barrels , bearings and shafts are attached. A work plate consists of a round blank in which holes and blind holes are milled. The spring mechanism , the gear mechanism , the pointer mechanism , the gear regulator and possibly also cadratures are mounted on a work plate (characterized according to assembly groups) .
The dial side of the work plate is called the underside and the other side is called the top . Work plates and their bridges are occasionally given additional designations such as caliber 3/4 work plate and 3/4 bridge , which refers to the length of the bridge relative to the diameter of the work plate.
In the case of a skeleton clock , the work plate is subsequently perforated, while in a minimal, figurative work plate, mechanically unnecessary parts are left out from the design.
