WATER RESISTANCE FOR WATCH

1. Non-water resistance

• If "WATER RESISTANCE" is not inscribed on the case back, your watch is not water resistance, and care should be taken not to get it wet as water may damage the movement.

2. Water Resistance (3 BAR)

• If "WATER RESISTANCE 3 BAR" is inscribed on the back, your watch is designed & manufactured to withstand up to 3 bar. Such as accidental contact with splashes of water or rain, but not designed for swimming or diving.
  

3. Water Resistance (5 BAR)

• If "WATER RESISTANCE 5 BAR" is inscribed on the back case, your watch is designed & manufactured to withstand up to 5 bar and is suitable for swimming, yachting, strong water exposure and taking a shower.
  

4. Water Resistance (10/15/20 BAR)

• If "WATER RESISTANCE 10 BAR", "WATER RESISTANCE 15 BAR", or "WATER RESISTANCE 20 BAR" is inscribed on the case back, your watch is designed & manufactured to withstand up to 10/15/20 bar and is suitable for taking a bath, shallow diving, but not for scuba diving. Diving watch should have a ISO Standard of Water Resistance (For e.g. Diver's 200m) inscribed on the case back or face dial.
  

5. Diver's 200m, Professional 300m & above (etc)

• 
  Do not swimming or diving with your watch unless it has a screw-down crown (also known as ‘screw-lock’ or ‘screw-in’ crown) and is water-resistant to at least 100 meters.
  

6. General

• Before using the water resistance 5, 10, 15 or 20 bar watch in water, be sure the crown is pushed completely. DO NOT operate the crown/buttons when the watch is wet or in water. If used in salt water, rinse the watch in fresh water and dry it completely. Watches that has a rotating bezel, turn the bezel several times while rinsing it. This will prevent salt buildup and corrosion of the bezel ring.

7. Note

• Pressure in bar is a test pressure and should not be considered as corresponding to actual diving depth since swimming movement tends to increase the pressure at a given depth. Care should be taken on diving into water.
  Besides that, try to avoid wearing watch while showering in hot tub or sauna. Such extreme heat may defect the gasket within. Over time, it may allow water droplets to penetrate the watch.
