Discover Emeraude 300

We don't build watches to tell time. Time is everywhere. We build them to be understood — every bridge bevelled, every screw blued, every second earned by a heart that beats twenty-eight thousand eight hundred times an hour.

— Élise Marchand, Master Watchmaker

01

Design

Two years of sketches before a single gram of steel is cut. The case profile alone went through 63 revisions.

02

Movement

Calibre V-70 is assembled by a single watchmaker, start to finish, then signed on the rotor.

03

Assembly

Dial, hands and bezel are fitted under a laminar-flow hood — not a single speck of dust allowed inside.

04

Testing

Twenty-one days across six positions and three temperatures. Then pressure-tested to 375 metres.

“The most quietly confident diver of the decade. You'll find yourself checking the time just to look at it.”
— Horological Review, 2026
