Stop fiddling with gauges and upgrade to the Garmin Descent Mk3i, arguably the most advanced dive computer watch on the market today.

Garmin introduces the Dive Readiness Tool, a first-of-its-kind feature that leverages lifestyle factors like sleep, stress, and exercise to let you know when your body is best prepared for a dive. For exploration and orientation, the DiveView Maps are invaluable, offering color maps with bathymetric depth contours and over 4,000 preloaded dive sites right on your wrist.
The watch is built tough with a bright 1.4” AMOLED display, a sapphire lens, and a 200-meter dive rating. Plus, the built-in LED flashlight works both above and below water, making it a versatile safety and signaling tool.

- Designed and built in Canada and depth-rated to 200 meters
The Shearwater Teric is the answer for divers who demand a high-performance air-integrated dive computer that doesn’t sacrifice style.
It’s a full-color, watch-style computer featuring a stunning, high-resolution AMOLED display that provides a bright, vivid interface. Built and designed in Canada, the Teric is depth-rated to a robust 200 meters.
The Teric is fully featured for every level. It includes five dive modes: OC REC (Nitrox to 99%), OC TEC (Trimix enabled for planned decompression), CC/BO (Closed Circuit Rebreather), Gauge, and Freediving. As an air-integrated dive computer, it’s able to connect with up to 4 Shearwater Swift transmitters, so you can monitor multiple tanks or your buddy’s pressure.
Durability is key, and the Teric delivers with a scratch-resistant sapphire window and a bezel and buttons constructed from marine-grade 316 stainless steel. Inside this rugged casing, a 3-axis, tilt-compensated digital compass gives you reliable underwater navigation.
Powering this computer is an internal rechargeable Li-ion battery, which gives you up to 30 hours in dive mode and up to 50 hours in watch mode. Recharging is effortlessly simple with the included wireless charging station.
Color options include:

Apple Watch Ultra 3
4.2
- The ultimate sports and adventure watch is built to last with an extremely tough titanium case and a strong sapphire crystal display.
- A large and advanced display that emits more light at wider angles.
- Up to 42 hours of normal use and up to 72 hours in Low Power Mode.
- If you don’t have cell service or Wi-Fi, built-in satellite communications let you text emergency services via satellite to get help.
I know what you’re thinking. “Why is a smartwatch on this list?” Well, the answer is simple. We’re talking about dive computer watches and what’s more of a watch than an actual smartwatch that you can wear every day and use for diving?
The Apple Watch Ultra 3 is built out of titanium and uses a Wide-Angle Always-on Retina LTPO3 OLED display. It uses a rechargeable Li-ion that can last up to 42 hours with normal use and is fast-charge capable, giving you up to 12 hours on just 15 minutes of charge.
The watch comes with all your usual smartwatch features, including health, sleep, and fitness tracking. It’s IP6X dust resistant and fit for recreational scuba diving up to 40 meters.
To turn this thing into a dive watch, you’ll have to get the Oceanic+ app. This app will give your watch full dive capabilities.
The app uses the Buhlmann ZHL-16C algorithm for dive planning and decompression management. It does everything a dive watch would do including: safety stop, no deco time, ascent/descent rate, dive planner, and more.
Unfortunately, a lot of the scuba diving features are gated behind a subscription. Oceanic offers these four plans:
| Basic | Snorkeling | Freediving | Scuba Diving |
| Free | $1.99 / mo | $4.99 / mo | $9.99 / mo |
Suunto Ocean

Underwater route tracking lets you visualize your path in the app afterward.

Connectivity includes dual-band GPS/GNSS, Bluetooth app syncing, and over-the-air firmware updates. Beyond diving, it supports over 115 sport modes with wrist-based heart rate, blood oxygen, altimeter, barometer, compass, and offline maps for navigation.

The Tern is equipped with Bluetooth wireless technology and can store up to 500 hours of dives in its dive log. The dives can be uploaded to the Shearwater Cloud app.
