In the year 2000 Chronoswiss made the word’s first serially produced regulator tourbillon. To celebrate the 20th anniversary of this achievement, Maik Panziera has designed the Open Gear Tourbillon – a modern mechanical timekeeper with a unique regulator set-up, electric blue case and a hypnotising handmade guilloché.
