What are the different waterproof levels in watches and how do we use them to know which is good for my requirements?
Water Resistance Ratings
Water resistance ratings on watches are measured in atmospheres (ATM) or bars. One atmosphere is equal to about 10 meters or 33 feet of water pressure. So, a watch that is rated for 50 meters of water resistance can withstand a water pressure equivalent to being 50 meters underwater.
Water Resistance Ratings and Activities
The following table shows the recommended activities for watches with different water resistance ratings:
| Water Resistance Rating | Activities |
|---|---|
| 50 meters | Splashes, rain, and showering |
| 100 meters | Swimming, snorkeling, and surfing |
| 200 meters | Scuba diving up to 200 meters |
| 300 meters or more | Deep sea diving |
Using a Watch in Water
If you are going to wear your watch in water, it is important to follow these tips:
- Screw down the crown and any other buttons on the watch before getting in the water. This will help to prevent water from getting inside the watch.
- Do not operate any buttons on the watch while it is in water.
- Rinse the watch with fresh water after being in salt water. This will help to prevent the salt from corroding the watch.
- Dry the watch thoroughly after being in water.
Diving with a Watch
If you are going to use your watch for diving, it is important to make sure that it is rated for at least 200 meters of water resistance. You should also make sure that the watch has a unidirectional bezel, which is a bezel that can only be turned in one direction. This will help to prevent you from accidentally setting the dive time too high.
Showers and Heat
Most watches that are rated for water resistance can also be worn in the shower. However, it is important to avoid getting the watch wet when using hot water or steam. The heat can cause the watch to malfunction.
Rain
Most watches that are rated for water resistance can also be worn in the rain. However, it is important to avoid wearing the watch in heavy rain or when the weather is very cold. The water can cause the watch to malfunction.
Here are some additional tips for keeping your watch water resistant:
- Avoid wearing your watch when you are doing activities that could damage it, such as working with chemicals or playing contact sports.
- Have your watch serviced by a qualified watchmaker every two to three years. This will help to ensure that the seals are in good condition and that the watch is properly lubricated.
Remember these differences between waterproof and water resistant watches:
- Waterproof watches are designed to withstand water pressure at a certain depth. They are typically used for diving or other activities where the watch will be submerged in water.
- Water resistant watches are designed to withstand water splashes and light rain. They are not designed for use in deep water or for activities where the watch will be submerged for extended periods of time.
Conclusion
By following these tips, you can help to keep your watch water resistant and in good working condition for many years to come.
