All Garmin Smartwatches — One Watch for Every Adventure

Garmin builds smartwatches with a consistent philosophy: every metric on your wrist should mean something, and the watch should be as capable on the trail, in the pool, or underwater as it is in the office. The result is a lineup that spans from the most accessible running watch to the flagship Fenix 8 — a dive computer, multisport trainer, and adventure GPS combined in a single device.

What you'll find in this collection covers every Garmin smartwatch family available at DiveCatalog.com: the Descent dive computers worn as everyday smartwatches, the Fenix 8 adventure series, the Forerunner running series, the Venu and Vivoactive fitness and lifestyle series, and the Approach golf series. Each family is built around a specific primary use case but shares the Garmin Connect platform, Firstbeat Analytics health metrics, and the same core health and wellness features.

The Garmin Smartwatch Families

Descent — The Diver's Smartwatch

Garmin's Descent series is the intersection of professional dive computer and full smartwatch platform. The Descent G1 Solar, G2, Mk3, Mk3i, X30, and X50i all function as complete Garmin smartwatches when not underwater — Body Battery, sleep tracking, fitness tracking, Garmin Pay, music storage, and 100+ sport modes. The Mk3i and X50i add SubWave sonar diver-to-diver communication and wireless air integration. Browse the Garmin Dive Computers collection for the full Descent lineup.

Fenix 8 — The Flagship Adventure and Dive Watch

The Fenix 8 is Garmin's flagship multisport adventure watch — and it includes a built-in dive computer with multiple dive modes, SubWave sonar capability (with T2 transceivers), and DiveView bathymetric maps. For divers who also run, hike, climb, ski, and paddle, the Fenix 8 consolidates everything into one device. AMOLED and Solar display options. 43mm, 47mm, and 51mm case sizes. TopoActive onboard maps with turn-by-turn routing. Built-in flashlight. Multi-band GNSS. Firstbeat Analytics for training and recovery. The Fenix 8 Pro adds LTE and satellite communication for off-grid connectivity without a phone. The Fenix E is a streamlined version at a more accessible entry point. Available in titanium, carbon gray DLC, and soft gold finishes.

Forerunner — Running and Triathlon

The Forerunner series covers running from first-time GPS watch buyers through elite triathletes. Entry models (Forerunner 55, 165, 170) provide GPS, Garmin Coach, and Body Battery. Mid-range (Forerunner 570) adds AMOLED, multi-band GPS, and expanded training dynamics in a compact 42mm or 47mm case. The flagship Forerunner 970 adds TopoActive onboard maps, built-in speaker and microphone, advanced triathlon features, ECG, and titanium construction. All models sync to Garmin Connect for training load, race predictor, and recovery metrics. Browse the Garmin Running Smartwatches collection.

Venu & Vivoactive — Fitness and Lifestyle

The Venu 4 and Vivoactive 6 are Garmin's fitness lifestyle smartwatches — designed for people who want comprehensive health monitoring, fitness tracking, and smartwatch functionality without the running- or adventure-specific depth of the Forerunner or Fenix. Body Battery, sleep score, stress tracking, Pulse Ox SpO2, animated workout guidance, Garmin Pay, music storage, and notifications. The Venu 4 adds a flashlight and multi-band GPS at the premium tier. Browse the Garmin Fitness Tracking Smartwatches collection.

Approach — Golf

Frequently Asked Questions — Garmin Smartwatches

What is the difference between the Fenix 8 and the Descent Mk3i?

Both are flagship Garmin watches with full dive computers and smartwatch platforms. The Fenix 8 is oriented around outdoor adventure — topoActive maps, navigation, extreme sport tracking, with diving as one of many activity modes. The Descent Mk3i is dive-first — it has SubWave sonar messaging, T2 air integration, CCR compatibility, and Diver Readiness as core dive-computer features. The Fenix 8 is the better choice for a diver who is equally a runner, hiker, or climber. The Descent Mk3i is the better choice for a diver who wants the best dive computer, with excellent everything-else smartwatch features as a bonus.

Can I use a Garmin Forerunner for diving?

No. The Forerunner series does not include a dive computer. If you want a Garmin that functions as both a running watch and a dive computer, the Descent Mk3i or Fenix 8 are the correct choices.

What does Body Battery mean?

Body Battery is Garmin's real-time energy reserve indicator (0–100) powered by Firstbeat Analytics. It combines HRV data from overnight sleep, stress levels throughout the day, and activity load to estimate your current energy reserves. A Body Battery of 80–100 indicates well-rested, recovered, ready for demanding activity. 20–40 indicates fatigue. It's particularly useful for dive trip planning — seeing your Body Battery before a dive day gives concrete feedback on whether you're adequately recovered.

Do all Garmin smartwatches have GPS?

All Garmin smartwatches in our catalog include built-in GPS. Premium models (Fenix 8, Forerunner 970/570, Venu 4) include multi-band GNSS for more accurate positioning. The Descent dive computers also use GPS for surface position tracking at the end of a dive.
