Waterproof smartwatches are still mostly niche products, but that is starting to change with the introduction of more smartwatches that are water-resistant to 50-meters and beyond. Most smartwatches have an Ingress Protection rating of IP68. These smartwatches have been tested to survive submersion in shallow water for a short period of time. The reality is that you should avoid regularly exposing them to water, and you should definitely not swim with them. IP68-rated watches are designed to withstand accidental water exposure and the occasional dunking but are not intended for regular wear underwater or for water-based activities. If you plan to expose your smartwatch to water regularly or want to swim with it, see the models below with better water protection.
“Waterproof” is used as a descriptive marketing term when it comes to electronics and should not be taken literally (as increasing depth, pressure, and time will eventually overcome most waterproof devices). “Water-resistant” is the more accurate term and commonly used when referring to traditional watches. This list focuses on smartwatches that are at least water-resistant to 50 meters. A 50-meter (or 5 ATM) water resistance rating is suitable for swimming. For activities like surfing or diving, a watch with 100-meter water-resistance is recommended. Those with active lifestyles who want the best water-resistance currently available should look into the following smartwatch models for 2017.
