Creating a new relationship between the minute and hour hands, this is a watch designed to make you think. Via a good deal of clever engineering, the hands move at the same pace, with minutes read from an outer-track that moves anticlockwise. 

SKOLORR Comments

An epitome of art in the highest form of watchmaking. The level of intelligence in this creation by Kari (fondly addressed by his first name in the independent community) is mind-blowing. For purchase enquiry, we are happy to connect you to Kari.

The Vingt-8 ISO bears a truly original display of hours and minutes. At the top of each hour, the minute hand overlaps the hour hand, whilst on every half hour, the hands are opposite. A moving chapter ring on the perimeter turns anticlockwise allowing the minutes to be read easily. In this configuration, the angle between the hour and minutes remains the same regardless of the time.

The design of the in-house movement combines respect for longevity and precision with classical watchmaking traditions. A unique balance-spring system allows perfect regulation of the watch to within tolerances. The escapement has two wheels and requires much less energy than a traditional lifting escapement, offering benefits in terms of stability. The elegant balance-wheel bridge offers an unimpeded view of the escapement and balance.


The Nobel Prize laureate, Daniel Kahneman, is best known for his work on the psychology of judgement and decision making. His book, Thinking, Fast and Slow, describes two ways for the brain to form thoughts – System 1 and System 2. Telling the time is an example of a System 1 activity: a glance suffices because the process is so familiar - you can tell the time without having to think twice. The Vingt-8 ISO counters this code.

Conforming to Kahneman’s System 2 behaviour, you can no longer read the time instinctively; the process is made more deliberate and logical. Because System 1 is no longer modus operandi, this creates a more intimate and reflective relationship with the watch. By Kari’s reckoning, taking a few seconds longer to tell the time, you end up knowing the time better because your attention is keener.
