At its Atelier Lucerne, Chronoswiss has sandblasted a hand-guilloché dial so that it diffuses light rather than reflecting it, which the brand calls a Chronoswiss first.
Chronoswiss today introduces the Pulse GMT Frosted Guilloche Gold, limited to 50 pieces. It brings 18-carat gold into the Pulse family, known for its onion crown and coin-edge bezel.

The hand-cut pattern remains, but its surface now has a frosted finish. The 41mm case holds 48g of gold and measures 13mm high. It comes on a new integrated black rubber strap, which Chronoswiss says is currently available only for this model.
Inside is the automatic Manufacture Caliber C.6002, developed exclusively with La Joux-Perret, with 55 hours of power reserve. A 24-hour disc at 9 o’clock shows the second time zone, while a 12-hour disc at 3 o’clock keeps home time in view.
Chronoswiss designed the movement for those who live between cities and time zones. Its dial no longer simply reflects light, but diffuses it — the same frosted idea, carried from surface to mechanism.
