The Bergeon 4040-P is a reversible, extensible movement holder designed to fit a wide range of watch movements.

It holds movements from 20 mm (8 3/4 ligne) to 43 mm (19 ligne).

This is the synthetic version of the Bergeon 4040, instead of a nickel finish.

The synthetic material is non-marring and will not scratch the workpiece under normal use.

It is sanded to remove rough edges and help protect the movement.

Swiss made.

Size: 58 x 38 x 20 mm.
