At the Chronoswiss Atelier in Lucerne, tiny stars of gold are cut and set by hand under magnification, then sealed beneath layers of fired blue enamel for the watch’s dial.
Chronoswiss today introduces the PULSE GMT Enamel Sky Gold, limited to 50 pieces in solid 18-carat red gold. It pairs the brand’s GMT case with paillonné enamel, one of watchmaking’s oldest and most demanding decorative crafts.
The dial begins as a curved white gold base, hand-guilloché on the same century-old machines as the rest of the family. Blue enamel is fired on layer by layer, and each firing is irreversible: dust, tension or a microscopic bubble can undo days of work.
Under magnification, wafer-thin stars of gold are cut and placed by hand, then sealed beneath a final layer of enamel so they float above the guilloché pattern beneath.
Inside is the automatic calibre C.6002, shared across the PULSE GMT family: a 24-hour second time zone on the left of the dial, 12-hour home time on the right. The idea goes back to an earlier Chronoswiss watch, the Tora.
The result is a watch built from two crafts at once, a modern travel movement inside a dial fired and finished entirely by hand.
