The waterproofing of LASIKA WATERPROOF WATCH depends on the waterproof rubber ring on the watch lens, back cover, and the handle to reach the corresponding standard. All waterproof watches are marked with the English words "WATER RESISTANT" or "WATERPROOF" on the bottom cover. Watches without water-resistance mark are only dust-proof and should be kept away from water. Thirty meters (3ATM, that is, three atmospheres) waterproof watch, can be used for daily grooming or use in the rain, that is, water droplets only splash on the surface without any water pressure on the watch.

At present, any type of LASIKA WATERPROOF WATCH, no matter how many meters is marked, can not be used in hot water (40C°). There are two reasons: 1. The permeability of water molecules is greatly enhanced when the temperature rises, and all waterproof watches are designed based on cold water. 2. According to thermal expansion and contraction, some components of LASIKA WATERPROOF WATCH will expand in different degrees under hot water conditions, which may increase the possible gap.
