• Water resistance rated to 100 meters, suitable for recreational diving, snorkeling, and surface swimming

Data Insights

Dive computer analytics demonstrate that divers using real-time monitoring devices like the Descent Mk1 improve dive efficiency by up to 30%, directly reducing decompression sickness risk and extending bottom time safely. The smartwatch displays critical metrics including depth, ascent/descent rates, dive time, and nitrogen loading in real-time, eliminating reliance on separate instruments and streamlining your gear configuration. Garmin Connect integration enables post-dive analysis, showing trends in dive duration, depth range, and heart rate patterns across 200 logged dives.

Usage Instructions

Before your first dive, configure your preferred gas mixture and dive mode through the watch interface. Use the pre-dive checklist feature to verify settings, then allow GPS to acquire satellites if recording navigation data. During descent, monitor the display for real-time depth and nitrogen status; ascend at recommended rates and follow all safety stops shown on the screen. After surfacing, sync data to Garmin Connect using Wi-Fi or Bluetooth on your smartphone to preserve detailed dive profiles, water temperature records, and heart rate graphs for post-dive review and future trip planning.

Design & Material

The Descent Mk1 combines technical ruggedness with refined aesthetics through precision engineering and premium materials. The stainless steel bezel provides impact resistance during rough handling and saltwater exposure, while the sapphire crystal lens resists scratches that typically plague dive watches in sandy or rocky environments. This certified refurbished model has been restored to like-new condition and tested to meet original specifications.

• Stainless steel bezel with brushed finish resists corrosion in saltwater and chlorinated pools
• High-strength sapphire lens rated harder than standard acrylic, maintaining optical clarity after years of use
• Lightweight polymer case body reduces wrist fatigue during extended dive days
• Textured silicone band with QuickFit spring bars allow tool-free strap swaps to accommodate dive gloves or dress wear
• Sealed buttons prevent water ingress while maintaining responsive tactile feedback
• Model 010-N1760-00 is fully compatible with all Garmin dive accessories and software updates released for the Mk1 line
