The movement has a very large balance wheel manufactured in-house, allowing perfect regulation of the watch to within strict tolerances. To equip such an exceptional timepiece, a very rare and unique balance spring system has been used. The exterior of the spring uses a typical Breguet overcoil, while the internal curve uses the little known Grossmann curve.
The escapement makes the movement very special; this is the first watch to have two escapement wheels in such a configuration. The escapement wheels give a direct impulse to the balance through the impulse roller/jewel. This escapement is extremely efficient and requires much less energy than traditional lever escapements, offering benefits in terms of longevity and stability in day-to-day use.
