NOTE: Before engaging in water-based activities, check the Specifications and Device Care section of the watch's owner's manual. Avoid pressing buttons when the watch is wet or submerged. If the watch gets wet, it should always be wiped dry before attempting to change settings or modes.
For more information on suitable and unsuitable activities, see the Water Ratings page on the Garmin website.

Garmin rigorously tests for water resistance by subjecting devices to various water pressure levels. While a majority of Garmin’s watches can withstand some water exposure, only devices with a water resistance rating of 5 ATM (50 meters) or higher are designed to withstand usage while surface swimming without resulting in damage.
