he mechanism of the KV20i was designed, built, fabricated, finished and assembled within the Voutilainen workshop. Thanks to its innovative architecture, the watch offers the opportunity to admire every detail of the movement, including the elegant single-arm balance-wheel bridge and the balance oscillating at a traditional frequency.

Additionally, it enables enthusias ts to appreciate at first glance the synchronized motions of the escapement wheels. On the case back, a purple dial and second counter are hand-guilloché adding a touch of elegance.

In terms of technique, the caliber features a very large balance wheel crafted in-house, allowing a perfect regulation of the watch within strict tolerances. To equip such a timepiece, a rare and unique balance-spring system has been used. The exterior of the spring has a typical Phillips overcoil, while the internal curve uses the little-known Grossmann curve further increasing accuracy.

The movement is particularly remarkable due to its two escapement wheels, which provide a direct impulse to the balance through the roller/jewel. This innovative construction improves efficiency by requiring less energy than the Swiss lever escapement and allows for notable benefits, for everyday use, such as longevity, stability and a longer power reserve.

Thanks to the reversed mechanism, it is possible to admire the movement that is meticulously finished to the highest standards by the expert artisans of the Voutilainen workshop. The surfaces of pinions and wheels are completely flat and polished with exceptionally uniform tolerances. The main plate and bridges, made from German-silver, are decorated by hand to achieve the utmost levels of surface finish. Screws and all steel parts are also finished and polished by hand.

Completing the design, the movement is housed in a stylish and elegant 39 mm titanium case paired with a hand - sewn black calf strap.
