In-house movement. Design, construction, fabrication, finishing and assembly in Voutilainen workshops. 65-hour power reserve
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 Phillips 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.
The balance-wheel bridge is sublimely elegant, offering an unimpeded view of the escapement and balance. It also allows the enthusiast to admire the extremely neat synchronized movements while watching the time.
