French watch making house swissmade collections

French watchmaking house, RESERVOIR was born from a man’s passion for measurement instruments of days gone by, which pace time, count revolutions or enumerate miles.

The house is settled in Paris, the capital of luxury and creativity, where she gives life to its watch collections inspired from objects of the past’s functionality and aestheticism. RESERVOIR are handmade in Switzerland at La Chaux-deFonds, in compliance with traditional craftsmanship and “Swiss made” label. Taking its inspiration from the functionality and the aesthetic appeal of vintage measuring instruments, RESERVOIR is meant to be the ref lection of eras full of cult objects, eras in which precision instruments were at the service of mankind. From automobile races with old cars to military aviation or the universe of submarines, measuring instruments are a source of inspiration both inexhaustible and powerful.

From a meter to a watch

RESERVOIR takes its inspiration from vintage car measuring instruments, and offers a radical time display by combining three horological complications, Swiss Made : the retrograde minute at 240° recalls the R.P.M. counters, the jumping hour recalls mileage meters and the power reserve display echoes the fuel gauges. RESERVOIR has joined forces with one of the best-know Swiss watchmakers, Telos Watch, specialized in designing high complication movements. A 124-components proprietary watchmaking module has, to this end, been specially drawn up and patented. The module is powered by an ETA 2824-2 movement, widely acclaimed for its reliability and precision.
