Looking for affordable everyday dive watches? How about the Casio Duro for just $50?
What does it take to convince you to buy the Casio Duro? (And no, Casio isn't paying me for this article.) It might be one of the most practical and sensible decisions of your life.
Indeed, Casio is the first choice when it comes to affordability, reliability, and functionality in watches.
I admit I don't always praise Casio as much as these watches deserve. I'm often distracted by expensive, luxurious models and collectible pieces that cost a fortune.
But not every investment has to empty your wallet. The Casio Duro is such a good deal that it feels like you're getting many features almost for free.
The Casio Duro is one of the most affordable dive watches in the world. The model has existed since 2011 and remains popular to this day. At first glance, it may seem that there's nothing special about these watches.
After all, they're just quartz analog dive watches with a black dial. Haven't we seen this combination a thousand times?
Yes, but try to find another brand offering dive watches for $50 that won't fall apart in a few months. I think you'll find it challenging.
The Casio Duro (also known as MDV106, 'Marlin', or simply 'Duro') is not a copy of the Rolex Submariner. Rather, it's an alternative and a tribute to the legendary model with everything you need for daily use.
Key Features of Casio Duro You Need to Know
Throughout the history of dive watches, we've appreciated their unique qualities: durability, readability, precision, and water resistance.
For its price, the Casio Marlin offers an impressive set of features that cannot be overlooked. For example, the reliable unidirectional bezel with 120 clicks performs excellently in tracking time underwater.
The luminescent dot at the '0' mark and the knurled edge are details that neatly enhance the design. It's worth noting that, unlike many competitors in this price category, the bezel perfectly aligns with the dial.
Well-crafted chamfers on the case and lugs give the watch a premium look. The polished and matte surfaces do not look cheap at all.
The strict and easily readable black dial is housed in a massive 44mm case, protected by mineral glass. The hour markers are typical for dive models - round and tapering shapes, complemented by a minute hand and an arrow-shaped hour hand.
The date window is located at the '3 o'clock' position, but without the magnifying glass in the Submariner style. The red second hand adds a bright accent and character to the dial.
The marlin logo - Casio's signature mark for dive watches - is applied on the dial and the case back. The watch is also equipped with a screw-down crown, recessed into the case and protected by guards - a nice and useful detail.
Given these features, it's clear why the Casio Duro has earned widespread recognition. It combines many qualities inherent in the best dive watches on the market.
Casio Duro Modifications
Already caught the Duro love bug? One of the side effects is the desire to modify the watch. Among Casio Duro collectors, this is a real trend.
Modifications can radically transform the watch. It all depends on whether you're satisfied with the base version or want to add some personality. Personally, I prefer the original.
If you're new to modding, you can consider several upgrade options. For example, replace the aluminum bezel with a sapphire or ceramic one. Changing the bezel color dramatically alters the look of the MDV-106 and is a popular customization method.
Other modifications include replacing the strap. Instead of the durable and comfortable plastic strap, you can opt for a NATO strap for a military style or a metal bracelet, bringing the watch closer to the Submariner look.
For a technical upgrade, you can improve the luminescent coating. Super-LumiNova significantly outperforms the standard Duro coating in brightness and glow duration.
Metal Bracelet for Casio Duro
For about $22, you can significantly expand the capabilities of the Casio Duro by installing an attractive metal bracelet.

Tightly fitting bracelets are rare in mass stores. However, Casio fans claim that the 'Oyster' style bracelet from eBay fits perfectly with the case. There are also seven holes for micro-adjusting the length.
Casio Duro 38mm - The Compact Version
The difference in the Duro design is that under the reference MDV-107, a wide selection of colored dials is available. For those wanting to modify or simply prefer variety, the Casio Duro 38mm model has appeared.
This was Casio's response to customer requests: 'Yes, we hear you! Here's a model for those with smaller wrists.' However, the model did not gain the expected popularity. Many believe that 38mm is actually about 36mm, which seems too small.

Besides the reduced size, Casio also cut some features. Instead of a raised ring with divisions, there's now a printed one. The lume colors disappointed fans, and the water resistance decreased to 50 meters.
Another downside was the bezel with 60 clicks and unwanted play. As a result, some claim that for $50, there are better small watch options.
A positive point was that the plastic strap was replaced with a steel bracelet with a folding clasp and buttons. Casio paid attention to this element.
Nevertheless, the Casio Duro 38mm, while remaining a worthy option for its price, did not generate the same interest as the classic MDV106.
Are Casio Duro Good Watches?
I won't hide it, the Casio Duro for $50 has its drawbacks. (You didn't expect me to say otherwise, did you?) However, yes, they are good watches.
The junction of the case and case back could be neater - the finishing needs improvement. Also, for those looking for dive watches for a thin wrist, 44mm might seem too large.

If you're not deterred by the size, finding other substantial complaints will be difficult. Yes, the watch doesn't meet ISO standards, but the 200-meter water resistance far exceeds what's available for $50.
So, are Casio Duro good watches?
Ultimately, these robust dive watches are visually pleasing and affordable. They are widely available, so you can buy them in almost any store. For those on a budget, this is an excellent option for everyday dive watches.
Why Casio Duro is Easy to Love
Whether you wear Casio or not, Duro is sure to make a good impression. If you've been hesitating for a long time whether to buy them, do it - literally dive in!
Swim, snorkel, play sports, or just enjoy the classic dive design. What do you have to lose?
For many collectors, the Rolex Submariner remains an unattainable dream. Those lucky enough to own such a watch often fear wearing it daily. The same goes for expensive professional dive models - nice to have, but not always convenient to use.
The Marlin doesn't hide its inspiration from the Submariner. Its goal is to offer a more accessible version of the legendary watches.
The Submariner is like an expensive sports car that you take out only on a warm day. It sits in the garage, polished, waiting for a special occasion.
The Duro is an everyday reliable car. It's sturdy, dependable, and ready for any weather conditions.
My advice - stop hesitating and buy the Casio Duro right now. Thank me later.
