The Best Dive Computer Watch

1. Suunto Zoop Novo: Best Entry Level Dive Computer Watch

It was not recently that I have been messing around with Suunto but with products like the Suunto Traverse Alpha, it’s hard not to have high expectations for the Suunto Zoop Novo. I am happy to report that this dive computer watch has met my expectations and then some.

Best Dive Computer Watch for Beginners

Dive experts and veterans will find the Suunto Zoop Novo to be quite basic. However, it has enough functions and features that make it perfect for beginners or simply for divers who prefer a basic computer.

Although it’s a basic dive computer, the Zoop Novo offers enough features for a safer diving experience. The big, easy-to-read digits ensure legibility while underwater. The Zoop Novo’s interface is fairly intuitive but complete beginners will likely need to read the manual to use the watch properly.

The Zoop Novo utilizes the Suunto RGBM (reduced gradient bubble model) for calculating decompression stops. One common feedback about Suunto’s dive computers is that they are too conservative. However, this is not necessarily a bad thing for an entry-level computer.

The Suunto Zoop Novo has a maximum display depth of 330 ft (100 meters) and will automatically trigger at 15 ft. The watch works great as a backup dive computer as well.

2. Oceanic Geo 2.0 Air/Nitrox: Top-Notch

Divers who prefer a mid-range all-rounder computer watch will have a lot to love about the Oceanic Geo 2.0 Air/Nitrox. On top of being a pretty good dive computer watch, it looks good enough to be worn as a daily wristwatch.

Top-Notch All-Rounder

The Oceanic Geo 2.0 Air/Nitrox is available in both white and titanium. As you can see from the picture, this is one good-looking watch and most people won’t have a problem wearing this on a daily basis. However, I am happy to report that it’s a reliable computer dive watch as well.

The watch features 4 operating modes: watch (complete alarm and countdown timer), norm (for Air and Nitrox dive modes), free dive, and gauge. One thing that I like about this dive computer is the Dual Algorithm technology which allows you to set decompression and no-decompression profiles. It’s also a breeze to program the watch to switch between two Nitrox mixes.

The watch also comes with flashing LED lights and an audible alarm that will notify you once you are approaching a no-decompression limit or going over a safe ascent rate. The interface is very easy to use and read and the computer can store up to 24 dives.

Whether you’re a beginner or an advanced diver, the Oceanic Geo 2.0 Air/Nitrox is a solid dive computer watch to consider.

3. Suunto D6i Novo: Best High-End Dive Watch

Divers with a sky-is-the-limit budget should consider getting the Suunto D6i Novo dive computer for its impressive technology and striking aesthetics. It’s no way a cheap watch so this option is definitely for a splurge.

A Dive Watch Worthy of a Splurge

The quality of the Suunto D6i Novo is a standout with its stainless steel bezel, steel casing, and silicone strap. The construction ensures that you’ll be having this for years. The watch is fitted with sapphire crystal glass display with anti-reflective coating. Even when underwater, the watch looks clear as day.

The D6i Novo features 4 diving modes: Air, Nitrox, Gauge and Freediving. Users can switch between three different gases and I must say that the interface is quite intuitive as well. There’s also the innovative apnea timer which is a godsend for freedivers.

Finding your way underwater is made easy by the 3D digital compass. Plus, it comes with a dive planner for storing multiple dive profiles and surface intervals.

My only gripe is that the battery is not rechargeable which means that a replacement will be necessary down the line. It might be an expensive freediving watch but the price tag is more than justified.

4. Cressi Leonardo: Best Inexpensive Dive Watch

The Cressi Leonardo is an excellent dive computer for under $200. It also happens to be the best-selling dive computer watch on Amazon, so it’s certainly worth the look.

Affordable and Gets the Job Done

The Cressi Leonardo is not intended to be used as an everyday watch but it features a rugged, low-profile design. What I love about this watch is its single-button interface. With just one button, you can easily operate the watch and access all of its features. It’s not the most intuitive out there but gains more points when it comes to ease of use.

Like most dive computer watches, the Cressi Leonardo comes with multiple modes: Air, Nitrox and Gauge. The edge-to-edge display is wide and easy to read. However, it does have some legibility issues when underwater but nothing too major. Thankfully, you can always toggle the backlight when visibility becomes an issue.

The watch also comes with a 60 dive, 70 hour logbook memory function which works great for progress tracking. An audible alarm is also present for added safety.

The Cressi Leonardo is a solid dive computer watch for beginners and experienced divers alike.

5. Mares Puck Pro: A Bang for Your Buck

The Mares Puck is considered to be a classic and was considered to be the best dive computer watch back then. The Mares Puck Pro is the updated version of the Puck and it comes with the much-needed improvements.

Simplicity and Ease of Use

If you are looking for a computer watch that’s a breeze to use, the Mares Puck Pro is one of the top picks. One of the first things you’ll notice about this watch is that it’s a bit bulky. It’s about 2 inches in diameter and nearly an inch thick. While this may seem like a drawback for many people, the large size allows for a larger screen display as well.

The large screen displays all the necessary information at a glance. The Puck Pro also features a single-button interface which keeps things simple. However, navigation can be quite tedious as you scroll through the many different functions.

The dive computer watch comes with 3 modes: Air, Nitrox, and Gauge. The watch also features audible and visual alarms for statuses like ascendance rate, decompression stop violation, exceed safety for ppO2/MOD, and low battery.

When it comes to the best dive computer watch, this one is definitely a bang for your buck.

6. Aqua Lung i450t: Best Dive Watch for Tec Divers

If you happen to bump into a tec diver, there’s a good chance he’s using a Aqua Lung i450t. The Aqua Lung i450t is the go-to dive computer watch for the most experienced divers.

Designed for Tec Divers

The Aqua Lung i450t dive computer features four different modes: Air, Nitrox, Gauge and Free Dive. Highlights include the multiple gas capability feature that can manage up to 3 Nitrox mixes (with 3 transmitters) and the Pre-Dive planning feature.

The four-button interface makes it a breeze to scroll through the menus and access the features that you want. It’s not that different when using your favorite G-Shock. Even in the most adverse condition, you should have no trouble using the Aqua Lung i450t while underwater.

The dive computer will automatically adjust depending on your altitude or whether you’re diving in fresh or salt water. It also comes with a digital compass that works surprisingly well. The display features a backlight and offers excellent visibility.

It’s not the most budget-friendly dive computer watch in this list but it certainly offers a great value.

Dive Safe

That’s it for our list of the best dive computer watch that you can buy in the market. A dive computer is just one of those gadgets that divers can’t leave home without.

Hopefully, this guide has helped you pick a reliable diving companion.
