Garmin Descent Mk3 Series Smartwatch

Sale priceS$1,839.00

Model: Descent Mk3
Size: 43mm
Color: Fog Gray


  • Advanced, watch-style dive computer, sized for smaller wrists, features a stunning 1.2” AMOLED display, scratch-resistant sapphire lens and 43 mm stainless steel bezel. 
  • Dive-first design with 200-meter dive-rated case includes metal leakproof inductive buttons and multiple dive modes for recreational to technical scuba diving and freediving. 
  • Enhanced SubWave sonar technology provides the ability to exchange preset diver-to-diver messages up to 30 meters (available with software v.15.70 or later) as well as monitor tank pressures and depth for up to eight divers within a range of 10 meters, when paired with the Descent T2 transceiver (sold separately) for group dive support. 
  • 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 — offering guidance that can help you make better-informed dive plan decisions. (data presented is intended to be a close estimation of metrics tracked)
  • Multi-band GPS technology provides superior positional accuracy while you’re out on the water, and built-in ABC sensors — including an underwater compass — help navigate every part of your dive from entry to exit. (GPS tracking does not work underwater)
  • Dive logs automatically sync with the Garmin Dive app downloaded to your compatible smartphone, allowing you to share and review data, track gear, post photos, take notes and more. 
  • Built-in sports apps help support your active lifestyle, offering fitness and training features that provide actionable insights for building strength and endurance. 
  • Get 24/7 health and wellness monitoring with wrist-based heart rate, advanced sleep monitoring, respiration tracking, Pulse Ox and more. (this is not a medical device, and data presented is intended to be a close estimation of metrics tracked; Pulse Ox not available in all countries)
  • Enjoy everyday wearability, and live connected with smart notifications, music storage, Garmin Pay contactless payments and more. (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.
