10 Best Garmin Dive Watches 2025 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 Descent Mk2i/Descent T1 Bundle is a top-tier dive watch that offers advanced features tailored for divers and multisport enthusiasts alike. One of its standout features is the enhanced 1.4-inch color display, which is larger and more readable than previous models, making it easier to view dive data even in bright sunlight. The water resistance and various dive modes, including the ability to monitor air pressure from up to five tanks, cater excellently to serious divers. The watch's battery life is impressive, lasting up to 32 hours in dive mode, which is essential for long underwater sessions.

Another strong aspect is its smart connectivity, allowing users to access multiple sports apps, music storage, and even Garmin Pay in eligible regions. Coupled with advanced metrics like wrist-based heart rate and Pulse Ox monitoring, it provides a comprehensive fitness and diving experience.

There are a few drawbacks to consider. While the watch's rugged build is great for durability, some users may find it slightly bulkier than traditional dive watches, which could affect comfort over extended wear. Additionally, the dive log feature is excellent for tracking dives but relies on a paired smartphone for sharing data, which might not be convenient for all users. Lastly, while the battery life is commendable, heavy use of smart features can drain it faster.

The Garmin Descent Mk3 is a stylish and highly capable dive computer designed for divers who want a watch-style device that fits smaller wrists. With a 43mm stainless steel case and a scratch-resistant sapphire lens, it offers strong durability and a premium feel. Its 1.2-inch AMOLED display is bright and sharp, making it easy to read underwater and in sunlight. The watch is rated for dives up to 200 meters and includes multiple dive modes that cater to both recreational and technical diving, as well as freediving.

Battery life is solid, providing up to 10 days in smartwatch mode and up to 30 hours during dives, so you don't have to worry about frequent recharging on diving trips. The watch also features metal leakproof buttons designed to withstand underwater conditions. Garmin's dive readiness tool is a helpful feature that estimates how your body’s condition might affect your dive, although it provides rough guidance rather than precise measurements.

Connectivity is strong with Bluetooth syncing to the Garmin Dive app, allowing you to review dive logs, track gear, and share experiences easily. The watch also supports everyday smart features like notifications, music storage, Garmin Pay, and health monitoring (heart rate, sleep, oxygen levels), making it versatile beyond diving. GPS doesn’t work underwater, but the built-in compass and sensors assist with navigation during dives. While some users might find the watch a bit on the heavier side due to its stainless steel build, the included silicone band and an extra strap help ensure a comfortable fit. This watch is an excellent choice for serious divers seeking advanced dive features combined with smartwatch conveniences, detailed dive planning tools, and durable build quality alongside fitness and health tracking for everyday use.
