Waterproofing is highly important for watches, but the waterproof rubber rings may gradually lose their function due to factors such as natural aging, temperature changes, external collisions or contact with beauty products, making your watch prone to damages. Your watch needs your careful protection.
Points to note for everyday wear of waterproof watches:
1. Waterproof rubber rings are prone to aging and should be checked and replaced periodically.
2. The waterproof performance may be affected if the crystal is damaged. If so, replace it immediately.
3. Do not operate the watch crown underwater, or when the watch is wet, to prevent water from entering the watch.
4. Reset the crown after use. If the crown has a spiral design, remember to screw it back into the watch tightly without leaving a gap.
5. Dry the watch after it comes into contact with water.
6. Avoid chemical substances from coming into contact with the watches, otherwise the case and the waterproof rubber ring will be affected and the waterproofing performance may be impaired.
7. Do not use the watch in high temperatures (+60 degrees Celsius) or low temperatures (-10 degrees Celsius) for prolonged periods.
8. If mist appears inside the watch, have it repaired immediately at Balco authorised repair service centres to avoid parts rusting.
9. Never wear watches in the shower or in saunas.
10. Familiarise yourself with the waterproofing capabilities of your watch. For everyday wear, contact with water should be kept within the threshold as much as possible. If the threshold is passed, use care to keep the water away.
1. The waterproofing capability is indicated on the dial, or the case cover, on most Balco watches.
2. On non-diving watches, the specific diving depth is not indicated, but is shown by ATM or M. ATM is an abbreviation of the standard atmosphere in English, with 1 ATM equivalent to 1 unit of pressure. Therefore, 2 ATM = waterproof in 20 m, 3 ATM = waterproof in 30 m, 5 ATM = waterproof in 50m waterproof and so on.
3. 30 m (i.e. 3 ATM) waterproof watches are capable of waterproofing in daily situations, suitable for wearing when grooming or when splashed with rain, meaning that water splashed onto the surface of the watch does not cause any pressure on your watch. 50 m waterproof watches are capable of enhanced waterproofing for daily situations, suitable for wearing when washing hands, face, vegetables and performing other household chores. They can be washed with a small amount of cold water, but cannot be immersed. 100 m waterproof watches can be used when swimming in shallow water; 200 m above waterproof watches can be used for swimming in deep water and diving.
4. Waterproof tests are carried out in static conditions by applying pressure to the watches for a few seconds to derive the maximum pressure compression values. Therefore, even if the watch is marked as 30 m or 50 m waterproof, you still must not wear the watch when swimming. Theory and practical experience tells us that a watch must be waterproof in actual underwater settings to at least 100 m (i.e. 10 ATM) before it can be called a watch with swimming functions. Watches with a diving function must be waterproof to at least 200 m (i.e. 20 ATM).
5. The waterproofing capabilities of a watch depends mainly on its crystal, case cover, crown and waterproof rubber ring. Over time, the waterproof rubber ring will gradually age, lose its elasticity, easily forming a gap, allowing water and dust to enter. Therefore, it is necessary to regularly check the rubber ring and replace it. (It is recommended that a watch be checked for waterproofing capabilities once a year. If the rubber ring shows signs of aging, replace it immediately. Otherwise, replace it every two years.)
6. The crown should be kept in its normal position. If the crown is a spiral design, screw it in tightly.
When the exterior of the crown is wet with water or dirt, wipe it clean before turning the crown to prevent water and dust from entering. Do not pull out the crown underwater to make adjustments.
