10 Best Garmin Dive Watches 2026 in the United States

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.

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 Pro is a high-end multisport GPS smartwatch built with premium materials like a titanium bezel and scratch-resistant sapphire lens, making it robust and durable for outdoor activities. It offers a 40-meter water resistance rating suitable for scuba and apnea diving, though it’s not a dedicated dive computer with advanced dive-specific features. The 1.4-inch AMOLED touchscreen is bright and clear, which helps with readability underwater and in bright conditions. Battery life is decent for a smartwatch with an AMOLED display and LTE satellite connectivity, but heavy use of communication features or GPS may reduce it faster.

Unique to this model is the built-in inReach satellite technology that enables two-way messaging, SOS emergency alerts, and LTE calls without a phone—ideal for off-grid adventures where safety is a priority. It also includes comprehensive health monitoring and multisport tracking, making it versatile beyond diving. However, the watch’s bulkier 51mm size and 90-gram weight might feel less comfortable for some users during long dives or daily wear. Additionally, many smart features require active subscriptions and can be limited by regional regulations.

While it performs very well as an all-around outdoor and fitness smartwatch with dive support, serious divers looking for specialized dive modes and detailed underwater metrics might find it less tailored to their needs. For users seeking a rugged, connected smartwatch with good dive capability and extensive outdoor features, the Garmin fēnix 8 Pro presents a strong choice.
