Victorinox Swiss Army Watch I.N.O.X. Professional Diver 241781. Additional protection comes from a detachable, transparent jelly fish bumper that also helps maintain a defined bezel position while diving. It incorporates a magnifying effect for good visibility and as an appealing reminder of diving watches of days gone by with their domed crystals. True to the I.N.O.X. credo of setting new watchmaking standards, these divers watches achieve water resistance to 200 meters, double that stipulated by the ISO 6425 regulation. They make their mark above and below sea level. Indelibly.
