Founded by François Moreau, Reservoir draws its identity from measuring instruments found in the automotive, aviation and marine worlds. Speedometers, pressure gauges and meters notably inspire its signature display combining retrograde minutes, jumping hours and a power reserve. Designed in France and Swiss Made, its watches bring the aesthetics of professional instruments to the wrist. The Hydrosphere collection applies this philosophy to diving, drawing direct inspiration from underwater pressure gauges. Reservoir also incorporates references to military history, notably through its jerrycan-inspired emblem. The brand thus offers distinctive watchmaking at the crossroads of mechanics, aviation, marine exploration and diving.
