What should I look for in an outdoor adventure smartwatch?

Prioritize battery life measured in days or weeks rather than hours, accurate multi-band GPS, a water rating of at least 5 ATM for swimming, and rugged build standards. Features like offline maps, a built-in flashlight, and solar charging matter most for multi-day trips away from a charger.

Are outdoor smartwatches waterproof?

Most quality outdoor smartwatches carry a 5 ATM or 10 ATM water rating, which covers swimming, snorkeling, and watersports. Note that a swim rating is not a dive rating - watches intended for scuba are dive-rated separately and include decompression features.
