Summer is here, and whether you are hitting the beach or the local pool, you probably want to keep your smartwatch on to track your swimming stats. But before you jump in, have you checked your watch’s waterproof rating? There is a common misconception that "waterproof" means you can do anything with your device. In the world of electronics, not all protection is created equal. Let’s decode the technical terms IP67, IP68, and 5ATM so you can use your COLMI Smartwatch Safely.

1. What do IP67 and IP68 actually mean?

The "IP" stands for Ingress Protection. It is an international standard that classifies how well a device resists dust and water.
The first digit (6):Represents dust protection. "6" is the highest level, meaning the device is completely dust-tight.
The second digit (7 or 8):Represents liquid protection.
IP67:The device can withstand immersion in water up to 1 meter deep for 30 minutes. This is perfect for hand washing, rain, or accidental splashes.
IP68: The device can withstand immersion deeper than 1 meter (usually 1.5m) for 30 minutes. It offers better protection than IP67 but is still mainly designed for static water pressure.

2. What is 5ATM?

If you are a serious swimmer, you should look for the 5ATM rating.
ATM stands for "Atmospheres." 5ATM means the watch can withstand pressure equivalent to a depth of 50 meters. Unlike IP ratings, which focus on static immersion, 5ATM indicates that the watch is built to handle the pressure changes experienced during swimming.

3. The "Kryptonite" of Smartwatches: Hot Water & Steam

This is the most important rule: Regardless of whether your watch is IP68 or 5ATM, you should never wear it in a hot shower, sauna, or hot spring.
Why?

  • ● Steam Molecules: Water vapor molecules are much smaller than liquid water droplets. They can easily penetrate the seals of the watch.

  • ● Temperature Changes: High temperatures can cause the sealing glue inside the watch to expand and degrade over time, destroying its waterproof capability.

 So, remember: Waterproof ≠ Steam-proof.

4. Maintenance Tips for Longevity

To keep your smartwatch in top condition, follow these simple tips:

  • ● Rinse After Salt Water: If you wear your watch in the ocean, salt can corrode the charging pins and casing. Always rinse it with fresh water and dry it immediately afterward.

  • ● Dry Before Charging: Never charge your watch while it is wet. Ensure the magnetic contacts are completely dry to avoid short circuits.

  • ● Avoid High-Speed Water: Avoid wearing your watch during high-speed water sports (like water skiing or diving) unless it is specifically built for diving, as the water impact pressure can exceed the rating limits.

Conclusion

Understanding your smartwatch's limits is the key to longevity. At COLMI, we rigorously test our devices to meet international standards. Check your specific model’s manual today to see its rating, and enjoy your workout—safely!
