The ability to Waterproof level of the Casio G- Shock watch.

 The waterproof level of the G-shock Mens Watch.


  


The waterproof, indicating that the water 50 meters to 100 meters or 200 meters are the pressures level of the test. This is not a true test dive.The movement of the dive pressure will increase over the measured depth. The waterproof level is specified that does not mean the Clock can be down to the actual water depth. but this is the ability of the clock to prevent the water pressure that equivalent actual deep water.

Handling water resistant, While in the water and make sure the crown is in the locked position to prevent water into the crown. Do not press any button while the watch is wet or in water.
After diving into the sea, Use water to wash the salt and dirt from the clock.Watches marked "DIVER’ S WATCH 200M "that can include scuba diving (with tank oxygen).

The following usage waterproof recommendations are suggested by the Casio.

• Water resistant to 30 meters (100 feet). Will withstand splashes or to resist rain, but should not worn while swimming, water related work and fishing or diving.
• Water resistant to 50 meters (165 feet). Suitable for showering or swimming in shallow water or white water rafting. non-snorkeling water related work, and fishing.
• Water resistant to 100 meters (330 feet). Suitable for swimming, recreational surfing, sailing and water sports and snorkeling.
• Water resistant to 150 meters (500 feet). Suitable for snorkeling.
• Water resistant to 200 meters (660 feet). Suitable for skin diving.
• Water resistant to Diver's 150 meters (500 feet) and 200 meters (660 feet). Meets ISO standards and is suitable for scuba diving.
• 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.

Water-resistance is measured in bars.

Water-resistance is measured in bars (unit of pressure, 1 bar being equivalent to 1 atmosphere), and watches are tested at these pressures for a certain period of time. Exceptional pressure, as when diving, may exceed those limits, so if you are a diving enthusiast you will need a watch that can tolerate those conditions.
Manufacturers often measure water-resistance to a number of feet, meters or atmospheres (atm).Normally, terms of depth imply that a watch will remain resistant at that (atmospheric pressure) depth in still conditions.

• 3 atm (30 m or 100 ft)= 3 bar : rain, gentle splash.
• 5 atm (50 m or 165 ft)= 5 bar : swimming, splashing in pool, but not heavy diving or jumping.
• 10 atm (100 m or 330 ft)= 10 bar : minimum for sport diving.
• 20 atm (20 bar) or more for serious diving.
