01 — The Movement

Anatomy of
an instant

Keep scrolling — the Calibre Un opens itself. Sapphire, bezel, dial, hands and the beating gear train, suspended in space.

02 — The Craft

Every bridge edge is bevelled and polished by a single artisan with gentian wood. Forty hours per movement — a mirror you will mostly never see.

The dial is fired at 820 °C, seven times. Two in ten survive the kiln. The rest are broken with a hammer, by tradition and by temper.

III

Steel hands are heated over an open flame until they turn — for two seconds only — the exact blue of a Genève dusk. Then they are pulled away.

Twin mainspring barrels in series hold four days of tension, so the watch outlasts your weekend — and most of your excuses.

“We do not build watches to tell time. We build them so that time, for once, has to earn its keep.”
— A. Éterne, Founder
