OBSIDIENNE
Most watches are admired for their face. Ours asks to be opened.
The Obsidienne M·72 — a manual-wind calibre of 231 parts, finished by hand over four months, sealed beneath a dial of hand-guilloché obsidian. Scroll, and we will take it apart for you.

Keep scrolling — the watch will open itself.
SAPPHIRE CRYSTAL
Box-domed, double anti-reflective coating.
OBSIDIAN DIAL
Hand-guilloché at 0.05 mm depth.
CALIBRE M·72
231 components. One pair of hands.
18K GOLD CASE
38.5 mm. Polished and brushed by hand.
It beats eight times a second, for three days straight.
The dial is cut on a rose engine from 1904.
One slip of the hand ruins eleven hours of engine-turning. There are no slips. There is no second dial.
A crown that winds like a bank-vault door.
Forty-eight flutes, cut then polished by hand. Resistance calibrated to the gram — scaled to a fingertip.
Worn beneath a cuff, it disappears. It was never for them.
38.5 mm × 8.9 mm — a presence felt, not shown.
Black alligator, gold pin buckle.
The dial faces the one who wound it.
