Garmin Descent Mk3 43 mm Stainless Steel Smartwatch with Fog Grey Silicone Band is sized for smaller wrists, it features a bright 1.2-inch AMOLED display with scratch-resistant sapphire lens, 200-meter dive-rated case, metal leakproof inductive buttons and multiple dive modes for recreational to technical scuba diving and freediving. DiveView maps offer bathymetric depth contours and more than 4000 dive sites to help you find where to dive and get oriented. Plus, a dive readiness tool, developed by Garmin, shows how lifestyle factors such as sleep, exercise, stress and jet lag can affect your body’s overall preparedness for diving – so, ultimately, you can make better-informed dive plan decisions (data presented is intended to be a close estimation of metrics tracked). No other dive computer does more to help you prepare for the physical and mental challenges of diving. You can also reference ABC sensors with a 3-axis underwater compass as well as surface GPS capabilities to mark your entry and exit points. When you’re ashore, built-in sports apps help you stay on top of your fitness, while Garmin Pay contactless payments, music storage and smart notifications keep you connected (compatible smartphone required). Battery performance: up to 10 days in smartwatch mode and up to 30 hours in dive mode — so you can dive without worrying about battery life and go longer between recharges.
