Waterproof Level
5 ATM 

*The device complies with the 5 ATM-rated resistance level under the ISO 22810:2010 standard, which indicates that it can withstand up to 50-metre static water pressure for 10 minutes, but does not actually mean that it is water-resistant in water that is 50-metre deep. The device can be used for shallow water activities, such as those in swimming pools or along the coast. It is not intended to be worn while diving, taking a hot shower, soaking in hot springs or saunas, or during any other activities that involve deep water or fast water flow. Remember to rinse the device with freshwater and wipe it dry after wearing it in ocean water.
Water resistance is not permanent, and performance may deteriorate with daily wear and tear.
