Introduced in Geneva last month, the Greubel Forsey Art Piece 1 is an amazing collaboration between watchmaker and artist. It features a 30° inclined double tourbillion, combined with a micro-scultpture, created by renowned artist Willard Wigan. The sculptures that Wigan creates are so small they are not even visible to the naked eye. So small intact, that Greubel Forsey had to build a microscope into the timepiece. This is unchartered territory, so it was no easy task to produce a microscope that has a large opening and enough light for a human eye to see in, without making the optic too big that it would ruin the proportions of the timepiece.
