Nocturne Perpetual · Reference AN-19
The hour,
held in titanium
A perpetual calendar that knows the length of every month until 2100, in a 41 mm grade-5 titanium case 9.8 mm thick. Three hundred and eighty-one components, assembled by one watchmaker, adjusted in five positions.
Chapter I — The calibre
Three hundred
and eighty-one parts
The AN-19 opens as you scroll. Beneath the dial: a 5N gold rotor, anglage chamfers cut by hand on every bridge, and a free-sprung balance with a Breguet overcoil beating four times a second. Scroll further and the rotor winds the reserve indicator on the dial above.

Chapter II — Materials
Titanium, sapphire,
and one polished bevel
Grade-5 titanium is milled from a single billet, bead-blasted on the flanks and mirror-polished on the bevels — a contrast that only appears after four hours at the tin wheel. The box-domed sapphire carries double-sided anti-reflective coating, so the dial reads as though nothing sits above it.

Chapter III — In the dark
It keeps reading
after the light goes
Eleven applied indices and both hands carry a two-layer chroma-lume charge. Fully lit it glows for eight minutes and stays legible for eleven hours. The room dims as you reach this chapter; the dial does the rest.
“We do not decorate a movement to hide it. We decorate it because someone will look.”
