Voutilainen Vingt-8 ISO

Unveiled at SIHH 2017, the Vingt-8 ISO wristwatch created by master watchmaker Kari Voutilainen boasts a completely innovative display of the time based on System 1 and System 2 human behaviour, as studied by Nobel Prize-winner Daniel Kahneman.

The time displaying pattern of the Vingt-8 ISO is briefly enumerated below:-
1. At the top of each hour, the minute hand overlaps the hour hand.
2. On every half hour, the minute and hours hands are opposite.
3. The circle of minutes turns at the same rate as the hour hand for easy reading.
4. The angle between the hour hand and the minute hand remains the same regardless of the time.
5. The position of the hour and minute hands, with respect to the other is always according to the minutes, whatever the hour is.
Daniel Kahneman, world renowned psychologist and Nobel Prize laureate in economics for Creating the field of Behavioral Economics, published Thinking, Fast and Slow. He describes two different ways to brain form thoughts – System 1 and System 2. Telling time by looking at a wrist watch is a result of a System 1 activity: a glance suffices because the « code » is so deep and familiar that in an instant you know the time without having to think twice. The Vingt-8 ISO counters this code; conforming to Kahneman’s System 2 behavior. You cannot read the time; you have to switch to System 2. It now creates a more intimate and reflective relationship with this watch – it takes a few seconds now to know the time; But you know the time better with the Vingt-8 ISO because your attention is keener.

The stylish 18k pink gold case measuring 39mm diameter houses an in-house mechanical hand-wound movement designed, built, fabricated, finished and assembled in Voutilainen workshop. The design and philosophy of the movement combines respect for longevity and precision with classical watchmaking tradition.

The movement has a very large scale manufactured in-house, allowing perfect regulation of the watch to within tolerances. To equip such an exceptional timepiece, a very rare and unique balance-spring system has been used. Phillips overcoil, while the internal curve uses the little known Grossmann curve.
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 lifting 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 synchronized movements of the escapement wheels.

The watch features finishing of the highest standards. The surfaces of pinions and wheels are completely flat and highly polished to 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.
