Our History
A century of pressure, salt, and silence — distilled into instruments worn by those who descend furthest.
▣ MARK 01
1904
The Atelier Opens
Zuccolo Rochet & Cie founded in France. The seed of a brand that would dive deeper than any other.
▣ MARK 02
1964
Marine Nationale Issue
The French Navy's combat divers select the Grands Fonds 300 — its crown moved to 6 o'clock for unmatched protection.
▣ MARK 03
1970s
Atlantic Trials
Field-tested off Brest. Repeated dives to 300 meters validate the ECS® cleaning system at depth.
▣ MARK 04
2010
The Réédition
ZRC reissues the legendary 1964 Grands Fonds, faithful in spec, modernized in metallurgy.
▣ MARK 05
2020+
Heterium · Abyss · Crimson
New limited series push the catalog into rarefied colors and titanium constructions for the next generation of divers.
— PRESENT DAY
The Legend Continues
Every Grands Fonds leaving our atelier today carries the same caseback engraving and the same crown placement that distinguished its 1964 ancestor.
