The watches can fulfill its function of water proof by water-resistant robber rings on parts of watch mirror, rear cover and the handle. Waterproof watches can not be used without any limits. While in use of these watches, we should pay attention to the following matters.

The waterproof rubber rings are easy to be aged and deteriorated, thus it is necessary for us to do testing of waterproof in fixed time. Once you find the bad performance of the waterproof function of your watch, you should replace the rubber ring.
No. 2 use the watch handle correctly
Do not manipulate the watch handle in the rain or in water or in any other damp environment in avoiding the stepping of humidity into the interior of watches. After use you should recover the watch handle to original situation to avoid the gaps between the handle and watch body.
No. 3 wipe water or dirt
Once the watches dipped with any water or any dirt, you should at once wipe away the water drops. And you should keep your watch far away from any chemical which would affect the watch case and waterproof rubber ring, and then the waterproof performance would be decreased gradually.
No. 4 keep you watch far away from high temperature or low temperature
You should keep your watch far away from any environment in high temperature or low temperature, and do not wear your watch under the environment in great temperature variation, such as hot-water bath, sauna, and swimming even when you work in the kitchen, since great temperature variation would cause expansion and contraction effects which would produce gaps and speed up the aging of waterproof rubber rings.
No. 5 remove steam and cloud point inside watches
If there is any water steam or cloud point inside the watches, you should remove it at once, otherwise it would cause rusting of watch parts, which would affect the timing accuracy of the watch.
