The Dials
Inspired by the shores of Swiss lakes, the Jura watch valley and the silence of Alpine snowfields, each dial interprets landscape through lacquer, engraving and light.
SPRING
The spring edition is the most romantic of the four. A deep violet lacquer flows over the sunray guilloché field, paired with a slate alligator strap and a burgundy lining — the chromatic memory of Swiss spring blossoms emerging through cool morning light.
“Geneva in April — magnolias breaking open against grey rain, the first warm hour of the year held in a single colour.”
SUMMER
Pale, luminous and expansive, the summer dial captures Swiss lakes at noon on a cloudless July day — the surface fractured by light, the sky and water merging into a single horizon of blue.
“Lac Léman from a boat at midday — pale above, deep below, light everywhere at once.”
AUTUMN
The tobacco brown dial is the most monochromatic of the four, drawing on chestnut leaves, walnut husks and the turned soil of October in the Jura watch valley.
“The Jura Watch valley in October — every shade of amber, rust and earth compressed into one hour of low light.”
WINTER
The winter edition is the most intense: near-black in shadow, blue in raking light, with dense concentric guilloché evoking frost and crystalline ice.
“Above the snowline of the Swiss alps — the world reduced to silence, shadow, and one infinite shade of blue.”
STORM
STORM joins the Four Seasons collection with a black guilloché dial and black alligator strap. Red chronograph and blue rattrapante hands bring sharp contrast to the dark dial.
Heritage in dialogue
The Four Seasons release keeps the original architectural logic of the early Ed. Koehn split-seconds pocket chronographs while translating it through contemporary guilloché, lacquer and steel casework.
