Chronoswiss Pulse GMT Enamel Sky Gold

With the Pulse GMT Enamel Sky Gold, Chronoswiss presents a timepiece that embodies its brand philosophy: Modern Mechanical.

The revival of the GMT function traces back to a Chronoswiss icon: the Tora. With its unconventional dual-time display, the Tora challenged traditional watchmaking and became a symbol of the brand’s independent spirit.

Today, this idea returns in a radically modern interpretation.

The Pulse family represents one of the most progressive chapters in Chronoswiss history. Architectural, bold and unmistakably contemporary, it carries the brand’s defining design codes: The onion crown, the coin-edge bezel and a strong mechanical identity rooted in independence.

The Pulse GMT is built for those who move between worlds – travelers and collectors whose lives unfold across continents and time zones. Yet with the Pulse GMT Enamel Sky, Chronoswiss deliberately brings together two seemingly opposite worlds: A modern timepiece paired with one of the oldest and most demanding decorative crafts in watchmaking.

The result is a watch where progressive design meets ancient craftsmanship – a rare combination that defines the spirit of Chronoswiss today. Limited to just 50 pieces worldwide.

A Sky Forged In Fire: Paillonné Enamel

Every Pulse GMT Enamel Sky begins with a curved, hand-guillochéd white gold dial, engraved in the Atelier in Lucerne on century-old machines. The pattern beneath the enamel creates the living depth of the dial.

Layer by layer, translucent blue enamel is applied and fired at high temperatures. Each firing is irreversible. Dust, tension or microscopic bubbles can destroy days of work in seconds.

Only when the deep navy base reaches its perfect intensity does the most delicate stage begin. Under magnification, wafer-thin gold paillons are individually cut and positioned by hand. Each tiny star is placed with microscopic precision before the dial returns to the oven once again.

A final, translucent enamel layer seals the stars beneath the surface. The gold remains suspended in glass, while the guilloché beneath continues to interact with the light.

What you see is not print. It is gold embedded in enamel above hand-cut geometry – crafted to last for centuries. This is the demanding art of paillonné enamel, executed in the Chronoswiss Atelier in Lucerne.

Solid Presence & Mechanical Integrity

The 41mm case, measuring 13 mm in height, is crafted entirely from 5N 18-carat red gold. Paired with the seamlessly integrated full gold bracelet, the Pulse GMT Enamel Sky becomes a sculptural object - carrying presence both visually and physically.

Inside beats the Chronoswiss Manufacture Caliber C.6002, developed together with La Joux-Perret. The movement offers 55 hours of power reserve and integrates a true two-timezone display:

• Left: 24-hour second timezone

• Right: 12-hour home time

• Central minutes and seconds unify both.

Limited to only 50 pieces worldwide, the Pulse GMT Enamel Sky is created for identity-driven collectors. For those who move between worlds and time zones. For those who do not follow trends, but define them. A timepiece that demands attention. And a collector who expects nothing less.
