With the Open Gear Tourbillon the ‘blue hour’ gets a whole new meaning. Using 10 different shades of the colour historically symbolising loyalty, strength, wisdom and trust, the calm display of the watch is contrasted especially by the energetic, almost aggressive electric blue CVD coating on the 17-part, stainless steel case.
Open Gear Tourbillon
Traditionally placed at 6 o’clock, the tourbillon is a perfect ingredient to incorporate in the Chronoswiss design lexicon.
