Waterproof watches are divided into ordinary waterproof and professional waterproof. Ordinary waterproof watches can only prevent water splashes, while professional waterproof watches can withstand immersion in different depths of water. The waterproofness of the watch depends on the waterproof rubber ring on the watch mirror, back cover, and handle to reach the corresponding standard.
All waterproof watches are marked with the English words “WATERRESISTANT” or “WATER PROOF” on the bottom cover. Watches without water-resistance mark are only dust-proof and should be kept away from water. The 30-meter (3ATM, or 3 atmospheres) waterproof watch can be used for daily freshening or use in the rain. That is, the water droplets only splash on the surface without any water pressure being applied to the watch. The 50-meter waterproof watch is suitable for swimming and general housework. The 100-meter waterproof watch can be used for underwater work such as swimming and diving.
Waterproof rubber ring is prone to aging and deterioration, so it should be replaced regularly. Or replace each time it is repaired. Damage to the watch glass can affect the waterproof performance of the watch. If it is damaged, replace it in time. Do not operate the crown of the watch in water or when the watch is wet. To prevent water from entering the meter. Push the crown to the end after use. Be careful to lock the turnbuckle crown on the watch without leaving a gap.
