Chapter VI — The Atelier
Made slowly, on purpose.
01Guilloché · Rose Engine
Engraved by hand.
On a century-old rose engine lathe, our engravers cut the dial line by line. Thirty-four passes, each offset by a fraction of a degree, until light itself begins to ripple across the surface.

02Gem Setting · Serti Clos
Set to catch light.
Each diamond is selected under 10× loupe, then held by eight hand-raised prongs. The setter works in silence — a single slip of the graver and the stone is lost.

03Anglage · Côtes de Genève
Polished until it sings.
Every bevel of every wheel is chamfered and mirror-polished with gentian wood and diamond paste. Invisible once cased — and that is precisely the point.
