10 Best Garmin Dive Watches 2026 in the United States

The Garmin fēnix 8 is a premium multisport GPS smartwatch that stands out with its bright 1.4-inch AMOLED display protected by a scratch-resistant sapphire lens, offering excellent readability even underwater or in low light. Its build quality is top-notch, featuring a durable titanium bezel and leakproof metal buttons, which contribute to its 40-meter dive rating — making it suitable for both scuba and apnea diving. Battery life is impressive, lasting up to 29 days in smartwatch mode and up to 84 hours with GPS active, which means you can rely on it for extended adventures without frequent charging. The watch includes multiple dive modes and sensors that improve navigation and tracking underwater. Comfort-wise, although it weighs a modest 102 grams and has a pebble gray band designed for wear during intense activities, some users might find the 51mm size a bit large for smaller wrists.

In terms of smart features, it offers Bluetooth, Wi-Fi, and USB connectivity, voice call capabilities, and off-grid voice commands that work without a phone connection. Health and wellness monitoring is thorough with heart rate, sleep, respiration, and even an ECG app, though this data should be seen as an estimate rather than a medical grade. It excels for multisport and outdoor use, including diving, though the relatively large size and premium price might be considerations for casual users or those seeking a more compact dive watch.

The Garmin fēnix® 8 is a premium multisport GPS smartwatch designed for athletes and adventurers. One of its standout features is its impressive water resistance, rated for depths of up to 40 meters, making it suitable for various diving activities like scuba and apnea. This is complemented by robust durability, featuring a scratch-resistant sapphire lens and a titanium bezel, ensuring it can withstand the rigors of outdoor use. The bright 1.4-inch AMOLED display enhances readability, even in bright sunlight, which is beneficial for outdoor navigation and diving tasks.

Battery life is another strong point, lasting up to 16 days in smartwatch mode and 47 hours in GPS mode. This longevity is helpful for extended trips or activities without frequent recharging. The advanced fitness tracking capabilities, including real-time stamina tracking and personalized training plans, cater well to serious athletes looking for comprehensive performance metrics.

On the connectivity front, the fēnix® 8 allows for phone calls and text responses directly from the wrist when paired with a smartphone, adding convenience. Its off-grid voice command feature is useful in remote areas where smartphone connectivity may be lacking. Comfort and fit are essential for long wear, especially during activities, but the watch size (47 mm) may feel bulky for some users with smaller wrists. Lastly, while the price reflects its premium quality, it may be higher than what casual users are willing to spend.

The Garmin Descent Mk3i is an advanced dive computer that doubles as a multisport GPS smartwatch. The watch boasts a 1.4-inch AMOLED display, which is clear and readable even in low-light conditions, and the sapphire lens adds durability by resisting scratches. Its titanium bezel and optional titanium bracelet enhance its build quality, making it suitable for tough underwater environments. Water resistance up to 200 meters ensures reliability during deep dives, and the multiple dive modes cater to both recreational and technical divers, including freediving. The SubWave sonar technology is a standout feature, allowing communication between divers and monitoring tank pressures, though the required Descent T2 transceiver is sold separately, which could be a drawback for some users.

The built-in LED flashlight with variable intensities offers enhanced visibility underwater, adding to safety and convenience. The dive readiness tool is useful for assessing your physical condition before diving, though it should be noted that the metrics are estimations. The DiveView maps and multi-band GPS provide excellent navigational aid, though GPS tracking does not work underwater. The dive log feature is handy for storing and reviewing dive data, with seamless integration into the Garmin Dive app. As a multisport watch, it includes fitness and training features, along with comprehensive health monitoring tools, though these are not medical-grade.

Despite the robust features, the watch weighs 165.9 grams, which might not be comfortable for all users during prolonged wear. Connectivity through Bluetooth and USB supports smart features, enhancing its functionality as an everyday smartwatch. The Garmin Descent Mk3i excels in providing advanced features for diving and multisport activities, but the weight and additional cost for full sonar functionality could be potential downsides.
