IMMERSION IMMINENTE. DESIRS D’EXPLORATION ET DE DEFIS INFUSENT LES SENS ET LE MENTAL…

Immersion imminente – Temps de plongée : 45 minutes, profondeur : 25 mètres. La pression monte. Désirs d’exploration et de défis infusent les sens et le mental. Rester concentré, le temps de vérifier l’équipement : Bouteilles, oxygène, détendeur, stabilisateur… Scellée au poignet, Hydrosphere, une montre à l’effigie des manomètres de plongée sous-marine, premiers instruments de survie des plongeurs. Lunette tournante unidirectionnelle avec double graduation, valve à hélium et indicateur de marche, RESERVOIR Hydrosphere affirme sa singularité avec une seule aiguille au cadran. Bousculant l’esthétisme des montres de plongée, elle porte en elle les piliers d’une immersion réussie : sécurité, fonctionnalité, confiance en soi comme en son équipement.

THE SWISS MADE LABEL

The RESERVOIR collection is a testament to the unique body of watchmaking knowledge that abides by the most stringent professional standards.

Qualified watchmakers design, assemble and check the meticulously calibrated settings of RESERVOIR watches in La Chaux-de-Fonds, Switzerland. The fact that the checks are so thorough, and that such attention is devoted to every minor detail, means that RESERVOIR is truly proud to display the SWISS MADE label: an emblem of high quality watchmaking achieved through a patented proprietary module comprising 124 components.

The movement

In order to fine-tune the precision mechanism so that the three complications on the timepieces can be displayed, RESERVOIR has joined forces with one of the best-known Swiss watchmakers, 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, oscillating at 28,800 alt./h.

All RESERVOIR watches feature a retrograde minute hand, a jumping hour and a 37-hours power reserve.
