VOUTILAINEN – 28ti Titanium Edition

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.

The watch is finished to the highest standards.

The surfaces of pinions and wheels are completely flat and highly polished to within exceptionally uniform tolerances. All finishing work on the main plate and bridges is by hand to achieve the highest possible levels of surface finish.

Screws and all steel parts are finished and polished by hand.
