As a novice recreational diver this dive computer does the job. I have the black nato i200c and i do not regret purchasing this computer. I have yet to go past 60ft with it and haven't put myself in Deco terrioity so i haven't tested the alarm features of the watch. the back light is a bit mind even in south florida clear waters. But its still plenty readable. The bluetooth logging is seamless and i love it. i wouldnt use it as a daily watch due to its semi bulkiness. i would recommend.

As a professional diver I expect a lot out of my gear. I am in the water more than out from March through December each year and spend the majority of my dive time as an instructor, divemaster or spearfishing guide in the northern gulf of Mexico. This is the only time I have had a computer that could do it all for me on my dives. The signal from computer to transceiver stays strong, the display is incredibly easy to read, and the compass works flawlessly. I have owned other computers but nothing that comes near to the OCI in performance as well as the bang you get from your buck. You will not be disappointed with this product.

Great computer for students!
I have recommended this computer to most of my divers and they are very happy with how easy it is to understand and to maintain safe dives. The numbers are easy to ready and the different colors are a favorite for the ladies. It is conservative but I rather have that than push the limits.

Great Computer, Perfect for all my diving needs, Perfect and effortless integration with my pod, Nitrox and Air dives switching between the two is nice and simple, Dive profile tracing, consumption rates, approximately dive time remaining on your cylinder and so much more everything you need in one place, Could not ask for better Computer, Just one downside to it Can not put it in sleep mode while it is in storage with my kit, So battery only last a year and a half at this stage, Once i have the battery replaced will lose my current logs on it and that a shame,

Love my Garmin MK2i. I use it for everything skiing, rowing, running and of course diving. Easy to use, battery life is great as well. The only negative I might say would be that it is a little big for smaller wrists, but it is a computer with a lot of functions. I would definitely recommend to anyone who does more than diving.

What Is A Dive Computer Watch?

Not to be confused with dive watches, which are basically depth rated timepieces whose main function is to tell time.  Dive computer watches are full-featured watch-sized dive computers that can make real-time decompression calculations.

Don’t let their small size fool you, thou. These small devices pack as big a punch and can have all the same features and capabilities as their larger counterparts. Including advanced features such as air integration, Nitrox capabilities, gas switching, and digital compasses.

Why Should I Consider Owning A Dive Computer Watch?

If you’re a scuba diver who’s serious about the sport, a watch-sized dive computer delivers the perfect combination of functionality and Style. Not only are they perfect for all your underwater adventures, but also looks great for a night out on the town, special event, or everyday wear.

Their small size also makes them a great travel companion for your next dive trip,  where reducing weight and saving space in your luggage is a major concern. Especially, with the rates, airlines are charging for checked-in luggage these days.

Many models are also equipped with a digital compass. Have you ever unpacked your dive bag only to notice that you forgot to pack your compass? This has happened to me once or twice before. But with a digital compass, you can simply set your computer to compass mode and you’re ready to go. The compass can be a little slow at times but get the job done. What makes them great thou, is many of the compasses can also be activated on the surface for land navigation.

Even if you already have the perfect dive computer, a dive computer watch also makes a great backup computer for fail-safe diving in the event your primary dive computer fails or malfunctions. Some models even have the capability to change its algorithm to closely match those of your primary computer

And, because you’re always wearing it, you will never forget to pack or lose your dive computer.

Did I forget to mention that they just look cool? Honestly, the first thing that comes to mind when you see someone walk in the dive center with a dive computer watch on is, this person is a serious diver.

What Should I Know Before Buying?

These types of dive computers aren’t for everyone thou. There are still a few things you should know about dive computer watches before you make the decision to buy.

If you are visually impaired or dive in low visibility conditions the smaller screen and digit might make them harder to read. The small buttons can also be harder to press when wearing thick gloves.

Also, because they are made to be worn on your bare wrist, the straps on many models are not long enough to go over a dry suit or thick wetsuit.

Changing batteries can sometimes be a pain as well. Because of their intricate construction, many do not have user changeable batteries and require an authorized service technician to change the batteries. So while you’re waiting for your batteries to be changed you’ll be out a dive computer.

The Bottom Line

Dive computer watches provide the perfect mix of style and functionally and has quickly become the new icon of the serious scuba diver, similarly to what dive watches were to the early scuba divers.

With so many dive computer watches to choose from these days, it is easy to find one that matches your personal style as well as your diving preferences and budget.
