These models represent a type of compensation balance designed about 1923 by [M. Paul Ditisheim] for use with elinvar hairsprings.

[edit] How it works

Each consists of an uncut mono-metallic ring with the addition of short bi-metallic bales to effect the small amount of temperature compensation required. In order to reduce the air friction and lessen the variations in time keeping which follow changes in the atmospheric pressure the compensating blades are placed in recesses in the rim of the balance. An advantage of the uncut balance is the absence of changes of shape arising from centrifugal forces, the differences between which in long and short arcs of vibration lead to complication in the adjustment of the hairspring.
