6 Best Smartwatches for Scuba Diving: (2025 Guide & Reviews)

Last Updated on November 5, 2025 by Luis Cooper

Are you looking for the best smartwatches for scuba diving?

Here, I’ve compiled the best-reviewed watches for you.

When it comes to scuba diving, choosing the best watch is crucial for safety and functionality.

Dive watches are specially designed timepieces that can withstand underwater conditions.

They typically feature high water resistance, luminous markers for enhanced visibility, and a unidirectional rotating bezel for accurate tracking of dive time.

Whether you’re a recreational diver or a professional, a reliable dive watch is essential for underwater adventures.

Which are the Best Smartwatches for Scuba Diving?

Here are my recommended top 6 Best Smartwatches for Scuba Diving:-

 

1. Apple Watch Ultra 3: (Best Smartwatch for Scuba Diving in 2025)

I took the Apple Watch Ultra 3 diving and used it as my main dive computer on two shallow reef dives and a pool practice session.

It stood out because the screen was easy to read underwater, the haptic buzz alerted me during my safety stop, and the depth/temperature readings matched my console.

If you dive for fun and want the convenience of a watch that works underwater, this one deserves your attention.

Why it works for divers:

Made for water and depth:

It’s rated for 100 meters of underwater use and follows the EN 13319 dive standard.

That means you can safely use it for regular scuba dives down to about 40 meters.

Bright, easy to read display:

The screen stays clear even in bright or shaded water—important when you’re glancing at your wrist for time or depth.

Useful for safety stops:

With the right dive app (like Oceanic+), the watch will buzz and alert you to the speed of ascent, depth, and how long to stay at the stop—not just the time, but also smart reminders.

All-day power:

Its battery lasts through a full day of diving and surface breaks without panicking over a low battery.

When you’re swapping gear or on a liveaboard, that peace matters.

What you get:

• Dive-ready build: The watch meets serious durability standards for water, dust, and rough conditions.

• Underwater tracking: With the right app installed, you see depth, dive time, and water temperature on your wrist.

• Smart safety features: Alerts for ascent rate, low pressure, or when it’s time to stop and decompress (for recreational dives).

• Normal watch features included: You still get your calls, fitness tracking, wrist-based HR, maps, and apps.

• Simple reset after dive: Rinse with fresh water, dry off, and you’re ready for the next round. No bulky computer needed if you’re doing fun diving.

Conclusion:

If you dive for recreation and want a watch that can track your dive, alert you to safety stops, and still serve as a daily smartwatch, the Apple Watch Ultra 3 is one of the best options available.

Just be aware of its depth limit and app-based approach—when you know how it works, it becomes a reliable dive tool.

4. Garmin Descent Mk3i: (Best Watch-Style Dive Computer)

 

I used the Garmin Descent Mk3i for a reef dive and a wreck training day.

What I liked most: the screen was easy to read, the alerts were clear, and I could check my gas and buddy info without hand signals.

This is not just a “smartwatch that can dive”—it’s a full dive computer with Garmin’s fitness features on top.

Why it’s great for divers:

Built to go deep:

The Mk3i has a 200-meter dive rating, a sapphire lens, and leak-proof metal inductive buttons.

It comes in 43 mm (1.2″ AMOLED) and 51 mm (1.4″ AMOLED) sizes, both bright and easy to read underwater.

All the dive modes you need:

Single-gas and multi-gas (air, nitrox, trimix), gauge, apnea/apnea hunt, and CCR/rebreather support.

If you progress from open water to tech, the watch grows with you.

Gas, buddy, and messages underwater:

Pair with a Descent T2 transmitter to see tank pressure and remaining gas.

With SubWave (sonar), you can check buddy data and send preset diver-to-diver messages underwater (range and speed are limited; messages can take time to send and require compatible gear).

Maps on your wrist:

DiveView color maps show bathymetric contours and thousands of dive sites, handy for planning and orientation at the surface.

Battery that fits real trips:

Garmin lists up to ~30–66 hours in dive mode (model/settings dependent) and as high as ~10 days (43 mm) / ~25 days (51 mm) in smartwatch use—good for a full dive weekend or liveaboard without daily charging.

51 mm bonus:

The big model adds a built-in LED flashlight for gear checks and night entries.

In the water: (what stood out)

• Readability & alerts: The AMOLED stayed clear in green water and shade. Haptic beeps and on-screen prompts made ascent-rate and safety-stop management simple.

• Buddy awareness: Seeing my buddy’s depth/distance and gas at a glance (with T2/SubWave) cut down on extra signals and kept our checks calm. (Remember: everyone needs compatible units for this to work.)

• Planning and logging: Pre-dive checks are structured (gases, alarms, transmitter link). After the dive, logs sync to Garmin Dive with maps and profiles you can review or share.

Where it beats typical “smart” dive watches:

• Tech-ready features: Trimix and CCR support go beyond recreational limits; SubWave adds team tools many smartwatches lack.

• Surface life matters: You still get Garmin’s sports tracking, health metrics, and navigation—useful on trips when you’re running, hiking to shore entries, or traveling across time zones. (The Dive Readiness tool also ties sleep, stress, and travel into your pre-dive decision making.)

Simple setup tips:

1. Before the trip: Update firmware, pair the T2 transmitter, set gases/alerts, and do a pool check to learn the screens.

2. On the boat: Confirm SubWave connections, pick the right dive mode (rec/tech/apnea), and lock your strap tight for stable readings.

3. Underwater: Follow your training. Use the alerts for ascent and stops; check buddy data as a backup to hand signals.

4. After diving: Rinse in fresh water, sync your log to Garmin Dive, add site notes while they’re fresh.

Conclusion:

If you want a watch-style computer that handles recreational and advanced diving with clear screens, long battery, air integration, and team tools underwater, the Garmin Descent Mk3i is hard to beat.

It covers today’s needs (open water, nitrox) and leaves room to grow (trimix, CCR), while still giving you Garmin’s everyday training and travel features between dives.

Buying Guide:

Water Resistance Rating:

• Ensure the smartwatch has a high water resistance rating designed explicitly for scuba diving. Look for a minimum of 100 meters (330 feet) or, better yet, a professional-grade dive watch rated to 200 meters (660 feet) or more.

Dive Modes:

• Choose a smartwatch with dedicated dive modes and algorithms. These modes should track dive time, depth, water temperature, and surface intervals. Some watches offer air and nitrox compatibility for mixed-gas diving.

Dive Log and Data:

• Look for a watch that records dive data, including dive profiles, maximum depth, and bottom time. The ability to store and analyze this information is crucial for tracking your dives.

Durability:

• A durable and rugged construction is essential to withstand underwater pressure and potential impacts. Stainless steel or titanium cases are expected for dive watches.

Battery Life:

• Consider the battery life, especially during dive sessions. The watch should last for multiple dives on a single charge. Some watches offer power-saving modes for extended use.

Visibility:

• Ensure the watch has a bright and easy-to-read display, even in low-light or underwater conditions. An always-on display option is beneficial.

Strap:

• Look for a comfortable and secure strap worn over a wetsuit. Silicone or rubber straps are standard for dive watches.
