Garmin Descent Mk3 Dive Smartwatch

The Garmin Descent Mk3 is an advanced dive computer and multisport GPS smartwatch built for explorers above and below the surface. With a bright 1.2" AMOLED display, 200-meter dive rating, sapphire lens, and leakproof inductive buttons, it’s engineered for serious underwater performance.
