The Voutilainen Vingt-8 wristwatch perfectly encapsulates the philosophy of Kari Voutilainen. Its elegant and strong mechanism is housed in a stylish and robust case. The in-house movement of the Vingt-8 was designed, built, fabricated, finished and assembled in its entirety in Voutilainen workshops. The design and philosophy of the movement combines respect for longevity and precision with classical watchmaking tradition.
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.
