Overall Customers’ Reviews

According to customers, the Duro MDV106B-2AV is one of the most famous models in 2021, especially for water sports.

With an affordable dive watch but good water resistance, approval most people buy them for all Casio Duro’s functions, which is a real bargain.

The only minus point is that its attached strap is a thin black plastic strap, which reduces the sophistication of the Duro watch.

Detailed Review

Size & weight 

Despite its luxurious appearance, this watch is not the pinnacle of style due to its plastic strap design. However, thanks to this strap design, the Casio Duro has a relatively modest weight compared to other dive watches of the same type. 

With a weight of 92g and a diameter of 44mm, it is comfortable to wear and suitable for all sports and entertainment activities. You can wear this on your hand all day without worrying about wrist fatigue. Sometimes, you may not even notice that you have a dive watch on your hand.


Honestly, this part of the Casio dive watch reviews is not the most interesting, but as mentioned above, we do not ask too much about this part because the price is not high. The case is stainless steel, polished with a brushed top. However, since this is a functional dive watch, it is expected to increase its scratch resistance more than it is. Therefore, you should be careful to avoid intense collisions.

Water resistance 

On the front of the watch is written “WR 200” – A standard parameter that appears on specialized models for diving. With a water resistance of 200 M, the Casio Duro is suitable for diving, swimming, or general handwashing.


A commendable point for Casio’s watch lines is the ability to display the second hand accurately. And Duro does this precisely.

What you need to do is pull the knob. Drag out the first level to adjust the date. Then, drag out the second level to change the time.

The movement is a Casio module 2784, 3-year battery life, and easy operating specifications. Watch Duro keep time with quartz precision. Casio puts the watch’s accuracy at +/- 20 seconds a month, but Duro wearers report that it gains/loses 1-2 seconds per week. Seriously, this has essential timekeeping for its price tag of around $70 (not yet discounted).


Glass is one of the critical factors to consider when choosing to buy a good watch. Most products use Mineral Crystal mineral glass.

Mineral watch glass is a type of safety glass with high hardness, and when broken, it forms small pieces that do not cause damage.

Many watches in the mid-range segment and below use mineral glass because they are cheaper due to the familiar material and ease of production.

However, a plus point for this glass is the ability to polish easily. As long as the scratches are not too deep or have been polished many times, the ugly scratches will be blown away, and the glass will be as beautiful as new. It allows them to be beautiful and long-lasting.


A standout feature of the Casi Duro MDV106B-2AV is its sunray finish. It’s a beautiful deep black with dark charcoal gray.

The word Casio is printed in the center of the top half of the watch’s front, along with the marlin symbol in the center of the bottom half, above the words “WR 200”. The marlin work exhibits commendable elegance and grace. When Casio uses the marlin symbol, they categorize watches that are water-resistant, suitable for diving, and easily recognizable by customers at first sight.

Casio added a date window at 3 o’clock, and that’s much appreciated. However, a few customers still think that the window is relatively small and less sophisticated compared to the layout of the entire front of the watch.

The hour markers are polished and painted with lime. They capture light effectively and highlight the dials against the black background. From there, users can see the time accurately without causing discomfort.


Let’s repeat this one more time in the Casio MDV106 review. To be honest, the black plastic strap gives the user a sense of lightness, but they are pretty simple and boring in terms of fashion.

The plastic strap will be helpful when using it for actual diving or swimming. Unfortunately, the tang buckle is made of polished steel, which is also quite slippery, making it difficult to hold when you need to adjust.

Other special features

Original Casio Duro Marlin watch’s identification features: The watch is blue, is made of hard glass, and has a bezel of the same color. In addition, the top and bottom of Duro are engraved with the image of a Swordfish squaring in the middle of the sea, which is eye-catching.

In addition, the hour markers of the watch have been replaced by luminous and round crowns.

A notable feature of the Duro watch is the anti-reverse bezel (unidirectional bezel). As a result, it can rotate with 120 clicks/round with almost no wobble.

How do I adjust my Casio Duro dive watch?

The Duro MDV106-2A has a crown with 3 control levels. To set the time, follow the instructions below:

  • Step 1: Drag the crown to the nearest position, hold the knob, and rotate it counterclockwise to change the date.
  • Step 2: Pull the knob to the furthest position. Turn the crown clockwise to adjust the time.

Tips: You should keep your hands dry when adjusting the time on the watch because this Duro crown is quite slippery.

Are all watch batteries the same?

All watches have different batteries, each model uses its specific type, and they are not interchangeable. For example, the Duro model uses 2 watch batteries 3377 (SR626SW).

You can easily replace this type of battery by removing the back of the watch.

No, it doesn’t.
