MDV106 Series | Unisex Analog Watch | 200M WR | Stainless Steel Case | Resin Band | 2 Hand Analog (HR, Min, SEC) | Date Display | Screw Down Crown/Screw Down Caseback | 3 Year Battery

I just received the watch, it's even more beautiful on the wrist, easy to adjust and read the time. It could have a magnifying lens over the date, but the design is very nice. It seems to be of very good quality. The rubber strap seemed a little too rigid; we'll see how long it will withstand the repetitive opening and closing motion. In any case, there's a compatible steel strap available for this model on Amazon for $15.00, so when I have to replace it, it will only be once. The manual doesn't provide any instructions on how to unlock the crown for date/time adjustment. It seems quite simple and obvious, but you just need to turn it counter-clockwise until you feel the crown is loose, then pull it out. The first click adjusts the date and the second click the hours. Excellent purchase, a very beautiful watch.

I am 80 and had many watches in my life, this one is 5 stars for quality and looks and reliability and price, wear it daily and love it. ❤️

Let me start this review by saying, had there been a 10 star rating, this watch deserves it! I watched at least a dozen reviews on YouTube (I know, I have no life) and decided to take a chance with it. I have a manufacturing background and the fit, finish, overall package is amazing for the money. The fact that it has a screw down crown, water resistant to 200 meters and a 120 click unidirectional bezel is amazing. The watch even has a nice weighty feeling and dose not feel cheap or cheesy. Even the included strap is comfortable and good quality. I currently own over a dozen watches including Seiko, Citizen, Tissot, and Tag Heuer, and I like them all but enjoy the looks, quality and value and wear the Casio quite a bit. *** Note, I have a 7 1/2¨ wrist and love the 44mm case size but it may be a bit overpowering for a small wrist. ***

The Casio MDV-106 (often called the “Duro” or “Marlin”) in its black dial version (typically MDV-106-1A or similar) is one of the most celebrated affordable dive watches out there. It’s a cult classic, famously worn by Bill Gates, and praised for punching way above its ~$50–$80 price point. Here are the key positive aspects: • Incredible value and bang-for-buck — At this low cost, you get a solid stainless steel case, 200m water resistance (suitable for swimming/diving), a screw-down crown, and a reliable Japanese quartz movement that’s accurate and low-maintenance. Widely known for being powerhouse or the best value diver — it is tough, reliable, and built to last with stories of it surviving heavy abuse. • Classic, versatile diver aesthetic — The black dial has a subtle sunburst effect (shifting from deep black to charcoal gray in light), clean high-contrast markers/hands, a unidirectional bezel, and the iconic marlin logo (on dial and caseback for the original versions). It evokes a Rolex Submariner vibe without copying it outright — minimalist, legible, and handsome on the wrist. The overall look is timeless and understated. • Surprising build quality and comfort — For the price, the 316L stainless steel feels premium with polished finishes and beveled edges. It wears lighter and thinner (around 12mm thick) than expected for a 44mm case, and many find it comfortable despite the size. The resin strap is basic but functional; but I switched it out for a black and grey nato strap. • Durability and everyday toughness — It’s a true “beater” watch — people rave about its ruggedness for daily wear, work, or adventures. The movement is quiet, accurate (often within seconds per day), and the battery lasts years. It’s not fancy, but it’s dependable and no-nonsense. • Legibility and functionality — Easy to read with large fluorescent markers ( lume is basic but adequate for the price — visible in low light without being exceptional). The date window is clear, and the bezel clicks positively. Many fellow reviewers and Reddit users (from r/DuroGang) call it a gateway watch into the hobby — affordable, fun, and impressive enough to spark compliments or even look like something much pricier. Downsides like weaker lume or larger size on smaller wrists are common mentions, but the positives overwhelmingly dominate for what it is. If you’re after a no-fuss, tough diver that delivers massive satisfaction without breaking the bank, the Casio Duro is still a strong recommendation in 2026. It’s legendary for a reason!

Watch with a great reputation (deservedly) for its good looks, water resistance, and reliably good quartz movement. Did I mention that Bill Gates has famously worn this watch?

I consider myself and by peers as definitely a watch collector and enthusiast at atleast at some level. I have everything Casio DW5600s to Omegas, Rolex Daytonas and know brands like Greubel Forsey and Alange-Soehne Phenomenal watch, accurate, and I used to work in a high end 4 star hotel in a exceptionally wealthy area with very wealthy clients and have gotten complimented on this watch many times, more times than even my Rolex Explorer 2 ever did. And to non watch people they’ve literally asked if it was Rolex. My only issue is the mineral glass does scratch a little too easily: The gold color option was not tacky or fake looking and wore well as an everyday or casual. I’m purchasing another one and having the crystal replaced with sapphire through a customizer though.

This watch looks better in person. The photos don't do it justice. This is a watch with an actual 44mm case diameter (I measured it myself) minus the crown protectors. The lug width is 22mm. The resin band is reminiscent of the ones on big G-Shock watches. Resin will crack, eventually from UV exposure and constant bending. And resin straps are comfortable, but in not hot weather, so I replaced it with a stainless-steel bracelet, which dissipates heat quickly. On my 6 inch wrist, I am surprised that it looks good on me, despite is large size. It is also comfortable to wear. The quartz movement is very, very accurate. I can understand why Mr. Bill Gates wears this model and other Casio watches. It is a handsome watch that is reasonably-priced, along with high-quality materials and design. It runs on battery power, which means I don't have to pay a lot to get it serviced like a mechanical watch.

As my eyesight gets worse with age, I was looking for a durable, waterproof, easy-to-read watch with a simple timer that looked great on my wrist. I own both a Fitbit and Apple watch – I was getting tired of being tracked all the time and getting notifications about everything (which yes, I know can be adjusted). I’ve owned Casio watches before and still have a G-Shock digital that’s been running great for almost 20 years, so after reading many reviews here on Amazon and elsewhere, it was an easy decision to make. I went with the black face and bezel model, although you really can’t go wrong with any of the other colors offered. It’s a classic diving watch that, in my opinion, looks sturdy, cleaner and more elegant than some of the more expensive competitors. Given Casio’s proven durability over the decades and the price point of this particular watch, you can't miss with this one. There are a ton of You Tube videos and review articles online about this diver (which is a bit of a cult classic it seems) – the vast majority of which are overwhelmingly positive, so I won’t add much more here that hasn’t already been stated there. One common “complaint” that I noticed though is regarding the stock watchband. Many are critical of it, but I tend to disagree. I did take the advice of some and tried a few different aftermarket bands – the Barton elite silicone, a Ritchie classic leather band, and a Ritchie nylon NATO strap (all available on Amazon). With the exception of the NATO, I personally found the stock Casio diver band the watch comes with to be the most comfortable of the others tried – not taking away from or knocking the others by any means, it’s just a “why spend the extra money” type thing for a $50-ish watch. Simply a personal thing… Re the NATO strap in my pics: I did keep the Ritchie Premium Nylon strap to compliment the watch. It really does dress it up and make the timepiece pop for more “formal” occasions if you will – and very comfortable too. For everyday use though, the stock classic diver-style band turned out to be the most practical for me – one I recommend over aftermarket options and especially for those in the trades or who are knocking around on the beach, out hunting, at the lake, etc. If I had to be critical of any aspect of this watch, it would be the luminescent capacity of the hands and markers – something also frequently mentioned in many of the reviews I read online. It’s marginal at best. When blasted with high intensity light, the markers glow brilliantly initially, but it does seem to fade quick. I mention it because if this is an important feature for you night owls, it is something to consider. For me, it’s acceptable and not enough of a factor for me to change my rating of the piece. Bottom line is that I highly recommend this waterproof diver. It’s superior quality with Casio durability and reliability at a price that can’t be beat. It keeps d***-near perfect time and doesn’t have to be charged on a daily basis or wound ever – just a simple, inexpensive battery keeps it going for a couple of years. You will not be disappointed with this one! Thx, DT Edit 2/2/2024: A word on timekeeping: Having owned this watch for a while now, it does GAIN a few seconds every month. I go to www.time.gov to set adjust time every now and then... It's still more accurate than my other watches though - amazing considering this is a $50-ish dollar piece. Highly recommend this watch!
