To those who know nothing about diving, the thought of wearing a watch while underwater might seem strange. Other than knowing what time of day it is, there does not seem any reason to wear a watch underwater, they might say.
However, as any diver knows, a watch can be crucial in being able to check how long you have been underwater, and even more crucially, keeping track of how long your air supply will last.
With Casio being one of the most respected manufacturers of watches in the world, in this article we are going to review five of the best Casio dive watches and highlight their top features.
Best Casio Dive Watch Reviews
Casio Men’s Duro Analog Watch
A first glance the ‘Duro’ analog Casio dive watch, might not appear anything special, given that it has a very basic looking appearance, but on closer inspection you will discover that it has more to it than just a black and white face.
We will start with this watch’s hands, and its markers, which indicate the hours. These are all luminous and can be seen when light conditions are poor. The watch also has a date indicator but this not luminous.
All of this is housed in a stainless steel case, and protected behind a hardened mineral glass crystal, which ensures that it is going to take a lot for this watch to suffer any scratches.
Surrounding the glass is the watch’s bezel, which is segmented in 10-minute sections from 0 to 60, except between 0 and 15 where you have individual minute markings.
The bezel feels very secure and that is crucial given that it is this which is going to allow you to keep track of those all-important timings underwater. You should also be aware that the bezel is anti-reverse so there is no danger of it accidentally moving and causing you to misread your times.
The strap is made of resin, which obviously suits its use in water, and while it may not be as durable as say, leather, it is certainly more suited to diving than leather or fabric straps are. Another aspect of this watch which most certainly makes it an ideal dive watch is the fact that it is water resistant to 660 feet.
- Water-resistant to 660 feet
- Anti-reverse bezel
- Luminous hands and hour markers
- Hardened mineral glass crystal
- Stainless steel case
- Anti-glare coating is poor
- May look too big on thin wrists
Casio Men’s Super Illuminator Diver Watch
Our next Casio dive watch is one whose appearance makes it as much a candidate for being worn for how good it looks, as it does for when you need it to track your diving times.
We’ve mentioned how attractive this watch is, and while many watches are very functional, but do not look especially appealing, this one bucks that trend. Its case is silver in color, and the strap matches that, as well as having a more traditional dress watch styling of its own.
While it may be suitable for going out, we obviously want to see if it is suitable for going into the water too, given that we wish to use it as a dive watch.
In terms of water resistance, it will remain so down to 330 feet, which will suffice for normal snorkeling and scuba diving to that depth.
Also important is the bezel, and on this Casio watch it has minute markings from 0 to 15, and 5-minute markings thereafter to 60. The bezel is also anti-reverse so there is no risk of it being moved back accidentally.
The crystal is made from mineral glass, so it is extra hard, and extremely resistant to scratches. The case and the strap are made from stainless steel, and thus will resist any corrosion, which is vital if it is going to be used as a dive watch.
- Tough mineral crystal
- Anti-reverse bezel
- Traditional styling
- Stainless steel case and bracelet
- Water-resistant to 330 feet
- At 5.5 oz., it is heavy
- Difficult to adjust bracelet
