Grönefeld GTM-06
This chiming wristwatch, the most complicated wristwatch ever created in The Netherland’s history, is a so-called tourbillon with a minute repeater mechanism, able to sound the exact time on tiny gongs held within its case. This type of wristwatch represents the watchmaker’s Mount Everest in the world of horology, requiring more than 6 months of careful construction, assembly and regulation before completion.
