Obsidian Nero

Hydrosphere, in layman’s terms, is defined as: all of the water on the earth’s surface. This watch was built for the water and was made to be a reliable tool while sailing the English channel or scuba diving off the coast of California. With the Hydrosphere on your wrist, you are equipped for wherever the wind takes you.    DIAL Obsidian Nero dial Coarse sand texture Hand-applied polished raised indexes with Swiss luminescent Raised date window Polished hands with Swiss luminescent CASE Case diameter: 42mm Thickness: 11.5mm w/ glass Brushed & polished stainless steel case Unidirectional rotating bezel Engraved case back Curved glass w/ sapphire coating 20ATM W/R & screw in crown Fold over deployant clasp with micro adjust MOVEMENT Ronda 515, Swiss Made Quartz calibre Diameter: 25.60mm – 1 jewel  Standard battery: 371  Battery life: about 45 months Instruction Manual
