Most users get confused in describing water proof vs water resistant smartwatches. Both terms are used interchangeably to describe water handling capability of a smartwatch.
But, there are significant differences between waterproof smartwatches and water resistant smartwatches. Here’s a comprehensive comparison to help you make an informed decision:
Water-Resistant Smartwatches
A water-resistant smartwatch can withstand some exposure to water but is not impervious to it. The level of resistance varies based on the device’s water resistance rating.
Common Water Ratings
Most smartwatches would come with specific water resistance ratings. Some of the more commonly used water ratings for a smartwatch are:
IP Ratings (Ingress Protection): These are typically expressed as IPX7 or IPX8 for smartwatches.
- IPX7: Can survive immersion in up to 1 meter (3.3 feet) of water for 30 minutes.
- IPX8: Can handle deeper immersion, usually beyond 1 meter, for extended periods.
ATM Ratings (Atmospheres): Atmospheres is a unit that is used to describe pressure. The ATM rating of a smartwatch is often used to describe water resistance of smartwatches. Some ATM ratings that are commonly used for smartwatches include:
- 3 ATM (30 meters): Suitable for everyday use, including splashes, rain, and brief immersion in water.
- 5 ATM (50 meters): Safe for swimming in shallow water.
- 10 ATM (100 meters) and above: Suitable for more intensive water activities like snorkeling or scuba diving.
These smartwatches have water resistance ratings. The smartwatches can handle some exposure to water. But, persistent or extended exposure to water may cause detriment to the smartwatch.
Waterproof Smartwatches
Waterproof ratings for smartwatch indicate a more comprehensive water resistance than the plain water resistant smartwatches.
Technically, “waterproof” implies that the device is completely impervious to water under specified conditions. There is a very low chance of water ingestion in a water proof smartwatch.
A water proof smartwatch has better ingress protection against water. On a similar note, the water proof smartwatches can handle extreme water exposure for extended periods of time.
Water Activities
The following water activities are supported by water-resistant smartwatches and waterproof smartwatches.
Water-Resistant Smartwatches
These watches are suitable for light swimming and shallow water activities like snorkeling (if rated appropriately). The plain water resistant smartwatches are not suitable for high-impact water sports, diving, or extended underwater use.
Waterproof Smartwatches
Smartwatches rated as waterproof would allow more exposure to more water activities. These are suitable for more rigorous water activities, including swimming laps, surfing, or diving (if rated for depth).
But, the waterproof smartwatches are not suitable for extreme conditions beyond the specified ratings (e.g., deep-sea diving without proper certification).
Conclusion
For casual users, a smartwatch with IP 67 or IP 68 water ratings should serve well. As a best case, any smartwatch with a 3ATM water rating would be a good option.
For more active users, smartwatches with ATM ratings of 5 ATM or 10 ATM would do well for organized activities and intense exposure to water.
