The timepiece is driven by the new in-house caliber KV21. Inspired by the KV20 movement, it has been developed to integrate complications requiring the entire surface of the main plate on the dial side, without significantly affecting the movement’s thickness. To achieve this, the escapement was subtly modified while preserving its original functioning. Following in the footsteps of the renowned VINGT-8, this caliber is destined to leave its mark on Voutilainen’s iconic timepieces.

The mechanism has been designed, built, fabricated, hand-finished and assembled entirely within the Voutilainen workshop with the utmost precision, care, and passion. It features a very large balance wheel crafted in-house, enabling precise regulation of the watch within strict tolerances.

dditionally, 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 caliber KV21 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.

The case back reveals a captivating view of the caliber KV21’s intricacies 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.

It can be personalized according to the owner’s preference, allowing the timepiece to become a unique piece. The interplay of textures and light brings the watch to life, reflecting the patience, passion, and skills invested in every detail, a true work of art.
To complete the design, the KV21 Tonneau is paired with an elegant hand-sewn strap.
