Open Gear Tourbillon

Chronoswiss 2021

ref. CH-3126-BLBL
Men's

Chronoswiss explores ten shades of blue on the dial, case and strap of this Open Gear Tourbillon, which opts for the regulator-style display of an off-centre hour dial at 12 o’Clock combined with a central minutes hand. Vertically aligned with the hour dial, at 6 o’clock, is a flying tourbillon. The blue lacquered dial is constructed on three levels from 42 components, with Côtes de Genève decoration on the bottom, hand-guillochage and hand-engraving on the middle level, and screwed-on skeletonised train-wheel bridges on the upper level, with gears visible through the hour display. The case comprises 17 components in steel, suffused with electric blue CVD plating.
