Dust proof, Shockproof, freezeproof, crushproof, Splashproof, rustproof, water resistant, waterproof and most importantly is it fool proof
If any of you are planning to buy a watch or GPS equipment and intended to take it for a swim, make sure it is IPX8 certified or 100m water resistant (refer to table below)
Most Garmin & Polar watch are IPX7 certified. An IPX7 designation means the GPS case can withstand accidental immersion in one meter of water for up to 30 minutes. An IPX8 designation is for continuous underwater use (www.garmin.com).
Most watch such as Nike, Timex, Casio & a few other sport watch are IPX8 certified or water resistant more than 100m.
Olympus camera are IPX8 certified with some NEW model such as the Olympus Stylus Tough-8000 are waterproof, freezeproof and crushproof (www.olympusamerica.com)
Watches are classified by their degree of water resistance, which roughly translated to the following (1metre = 3.2808398950131 feet);
|Water resistance rating||Suitability||Remarks|
|Water Resistant 30 m or 50 m||Suitable for water related work and fishing.||NOT suitable for swimming or diving.|
|Water Resistant 100 m||Suitable for recreational surfing, swimming, snorkeling, sailing and water sports.||NOT suitable for diving.|
|Water Resistant 200 m||Suitable for professional marine activity and serious surface water sports.||NOT suitable for diving.|
|Diver's 100 m||Minimum ISO standard (ISO 6425) for scuba|
diving at depths NO
T requiring helium gas.
|Diver's 100 m and 150 m watches are generally old(er) watches.|
|Diver's 200 m or 300 m||Suitable for scuba diving at depths NOT requiring helium gas.||Typical ratings for contemporary diver's watches.|
|Diver's 300+ m for mixed-gas diving||Suitable for saturation diving (helium enriched environment).||Watches designed for mixed-gas diving will have the DIVER’S WATCH L M FOR MIXED-GAS DIVING additional marking to point this out.|
