BASEPLATES, PLATES
FOR ADDITIONAL MECHANISMS AND BRIDGES

Baseplates, plates for additional mechanisms (modules) and bridges must have:

  • Polished chamfers.

  • Straight-grained sides.

  • Circular-graining or finishes that eliminate all machining traces.

  • Smoothed-down bridge supports.

  • Polished bevels in holes and recesses.

  • Polished sinks for jewel holes.

The tops of bridges must be finished with Geneva stripes or any other decoration that eliminates machining marks.
