In the horological world, Skeleton watches are some of the most tricky to design and build since all of the timepiece's inner workings are completely exposed and visible at all times. They can also be a great teaching aide, which is why Swiss watchmaker Audemars Piguet hired artist Krzysztof J. Lukasik to create this tool that lets watch owners learn more about the investment.
Nineteen steel laser-cut slices fan out like a Pantone color chart, but are instead used to reveal the intricate mechanical layers and elements of Audemars Piguet's Skeleton watch. Given as gifts to the company's clients, each layer also includes an explanation of what it does, how it works, and why the $30,000 they spent was totally justified. [Krzysztof J. Lukasik via Notcot]
