Nie wiem czy Omega certyfikuje ISO , ale zawsze można sprawdzić swoją markę zegarka
According to the Organization, the newly revised ISO is intended to ensure that if, for instance, a watch has a 30 meter water resistance, the watch is then suitable for any and all "aquatic activities" of any kind, up to 30 meters' depth – irrespective of the manufacturer. In practice this should mean that while your 50 meter water resistant watch isn't a dive watch per se, that if you do dive with it to, say, 20 meters, it shouldn't spring a leak – on the assumption that its date of manufacture is after the ISO went into effect, of course.
