Casio MRW200H Review

My full review of the Casio MRW200H is live! Be sure to check it out for more information about this cheap little diver.

See it here.

I recently purchased a $15 Casio MRW-200H dive style quartz watch, in order to see just how suited for actual diving such a cheap watch could be. 

With its cheap bidirectional bezel (real divers feature unidirectional bezels), lack of any kind of lume, and crown that doesn’t screw down the Casio MRW-200H is by no means an ideal watch for diving. It is however, very very cheap, which is a feature all of it’s own.

In the video below, I take the watch through a few simple tests before taking it on an actual dive. First, a simple immersion test in a foot of water. Of course a watch with 100 meters of water resistance will handle this no problem, right?

Unfortunately, not always. I’ve had watches with similar depth ratings fail before just going for a swim. Sometimes quality control is not so great. So it’s worth checking if a new watch can even get wet without failing before going deeper.

After that, it’s off to the deep pot! A deep pot is a small pressure tank with a see-through lid. The item you want to test is place in shallow water in the bottom of the tank, and then air pressure is added into the pot in order to simulate going down to depth.

I placed a small depth gauge besides the watch in order to visualize the depth reached.

First, it was quickly down to ~125ft and straight back up. A few bubbles formed around the bezel when ‘ascending’ back to the surface, but no water appears to have entered the watch.

After that, I took it down to 140ft, with a few ups and downs along the way. The ups and downs add quite a bit more stress than a simple down and back up. 

So far, the Casio MRW-200H is doing just fine. Next test is to take it out to the salty Puget Sound for a real dive!
