About this caliber
Self-winding, open-worked movement. In an effort to increase stability and precision a second balance wheel and balance-spring are mounted to the same axis as the original, in effect increasing the mass and thus inertia over the use of a single balance assembly of the same size.
Movement shown from the dial-side.
