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

This Casio watch exceeds expectations. It has a classic, elegant design that goes well with any style and feels durable and well made. It’s comfortable to wear, easy to read, and very accurate. The quality is excellent for the price and shows why Casio is such a reliable brand. Definitely a purchase worth making.

The CASIO MDC106 is a classic analog diver watch with a steel case and 200-meter water resistance. This elegant timepiece represents not just functionality but a deliberate choice to step back from the digital noise that saturates modern life. Personal Context: I owned one of these as a teenager many moons ago. Picking one up again for nostalgia reasons proved to be one of my better recent purchases—seeing it back on my wrist brought genuine satisfaction and memories. What Works: The watch delivers everything an analog timepiece should: date dial, elegant face, unidirectional bezel, and a resin band that sits snugly and comfortably on the wrist. The timekeeping is accurate and reliable—critical in my video production work where seconds matter in synchronizing equipment and maintaining production schedules. The Larger Point: This isn't just a watch—it's a statement about reclaiming simplicity. I'm done with digital watches loaded with bells and whistles I never use. Analog life is manifesting itself more deliberately in my daily routine, and this timepiece is part of that transition back to simpler, more intentional living. Bottom Line: Casio has always been a reliable brand, and this watch proves why. Elegant, comfortable, well-made, and the price point makes it accessible. Highly recommended for anyone seeking quality analog timekeeping without unnecessary complexity. They say Bill Gates uses one.

1st thoughts .... solid feel, good size, great specs, Not to Big, looks nice, Marlin a must, and Great overall value!!! This is my 1st dive watch and I'm very happy with this purchase. I did get the metal Casio strap, and I have also purchased a Malinese mesh metal strap (I like the look). Yep, this surely meets the hype at twice the $66 price I paid IMO!!!

I received this watch on 1-20-2018. I received my first Casio watch on Christmas morning somewhere around 1979. That watch, a simple, black plastic digital one, kept working for about 15 years, on the same battery. This wasn't any great feat in my mind at the time. It was just all I really knew, except for the time when I got an Armitron calculator watch at some point. Not only did the Armitron not last, it also felt like it wouldn't last. The buttons were flimsy, the edges rough, and it had an overall plasticky feel, even though it was gold. My old Casio shined by comparison. My dad got himself the same one as me that Christmas, except in stainless, and anytime it came up in later years, he'd laugh and say something like "David, I think I wore that watch for thirty years and I only replaced the battery once." So that is what Casio is in my mind. One time at the office I said to a coworker that Casio was the best watch in the world. Of course he laughed and quickly pointed out that there are FAR better watches. And he was certainly correct, but not for the money. I've had a few other Casios in my life. A Forester model which was really cool because of the forest green color and the fact that it was a fishing watch. What "fishing watch" actually meant was that it would tell you the about the ocean tides. Living in New Mexico, this was totally useless, but I still liked the little fish that would appear when the tide was high or something. Another Casio I got was the one with the world time with the atomic clock sensor. This one was a little off. The light stopped working after a while and setting it was a pain. But it's still ticking in my drawer right now after eight or so years and I still wear it here and there. But probably not anymore. This watch...this watch has me all smiles. I don't really have words to say. I'm not necessarily a "watch guy" in that sense, but I have always had one on my left arm since the age of ten or so. And honestly if it wasn't for Casio, I probably would have skipped wearing one mostly. Casio doesn't always hit it out of the park. After all they live and breathe like the rest of us. Maybe that's what makes this one such a beauty. I bought a very nice Bulova a couple years back for around $400. I like that watch. I get compliments on it and for good reason. It's solid. It's heavy. They paid very close attention to the design and the finish is beautiful. It feels like a $400 dollar watch or more. It is perfect for wearing to the office. Well, not really. Not since 1-20-2018. I don't dive. I have never diven (?) OK I have never dived. But something about a watch that is designed to be SIX HUNDRED FEET UNDER WATER AND STILL WORK gets me interested. There are many watches that can do this and much more, but they are not this watch. If I was a Viking, this would be the watch I wore. So what can I say? Yes, the date is comically small. I need reading glasses for small print and still can't read the date with them on. I guess most people who have not just come out of a coma should know the date. Touche, Casio. Oh and the Lumiglo or whatever is weak and nearly pointless, but at least it's there. I do like to light it up with my phone flashlight and look at it in the closet, however. But if I tap the crystal with my fingernail you know, it feels like I am tapping bulletproof glass. The bezel has a great click and I actually find myself using it! I use it to time my commute, or to time how long the waiter takes to bring the food out after I order. This is the kind of watch that is not going to win you any likes or impress anyone, unless they are a very smart, unselfish engineer type. Maybe. With my Bulova, people have actually wanted to hold it, they have examined it closely and then complimented me on it, gave it back, and then looked at it on my arm as if they may mug me later. This one won't really do that. You are the only one who will ever truly appreciate what this watch is. It's a secret love affair. I like that about it. A few things that I will say that I haven't read about it in those other reviews. The band for one thing. It's pretty good. It looks all plasticky and horrible in the pictures, I thought anyway. But in fact it is pliable, if not supple, and rather well proportioned, if not svelte. The clasp is also sort of excellent. It's not cheap. It's like they actually realized that the clasp is just as important as the other parts. It's like some executive with Casio said "The clasp is the most important part of any watch. It's what keeps it on. Make it beefy." Yep. That's exactly what happened. It is well made, with a soft, rounded finish, and it makes a nice clink sound when you are putting it on. There's really nothing more to say. Except when I look at this watch to see what time it is, I know the time within .003 seconds of my eyes seeing the face. It's just so clear. And functional. And simple. I never really thought about that with any other watch, and I love it. So I'll stop now, but expect an update when this watch becomes less of what it is now, or in the year 2040, whichever comes first. ***UPDATE*** April 27, 2021 The watch has become slightly less of what it was then, but not really. Let me explain. This thing has lived on my arm most days since I bought it. That's about 1,200 days. Before you ask, I do not take the watch into water. No showering with it, no swimming with it. I don't sleep with it, but I do remodel homes here and there and other sweaty messy things too and it gets dirty sometimes. Anyways, my first tiny little bummer happened last June, though it was so tiny I did not do an update. The bummer was that the battery died. Bummer. So I took the watch in to some random fancy jewelry store I found on Google maps, and they replaced the battery. I waited five days for the job to be completed and it cost twenty bucks. I got the watch back and all was well. Then about four months later it died again. This time slightly more furious, I went to a little jewelry store I happened to be driving past and this guy took it apart, checked the battery, which he said was perfect, cleaned it really well and said it was probably just dirty inside. I suspected shoddy workmanship and/or a lack of attention to detail on behalf of the fancy place. So I was on my way with a clean, healthy watch. The guy didn't charge a dime and did this on the spot and it took five minutes. He was a pro. The watch actually seems to keep even more perfect time since that happened. Seriously. And then the other day the band broke while putting it on. (See pictures) I just ordered a genuine replacement band from Casio, and I noticed in the pictures that the replacement says Casio JAPAN on it, while my original one says CHINA. (See pictures) So I have high hopes for the new one. Other than these two things, the watch has been stellar.

When I was in junior high, this watch came out brand new, and it was the hottest thing that all the girls wanted. I was one of those girls. My sweet mother saw to it that I got that watch for Christmas! I LOVED that watch. Groups of us would go to the movies; there was always an occasion for the need of a light — somebody dropped something and needed to find it … somebody spilled food or drink and needed/wanted to clean up the mess … one of us always needed something in our purse and needed to be able to see inside it to find the coveted item … or the movie just sucked; but I paid good money to see it; so I’d frequently check my watch for the time, to estimate how much longer I had to suffer through it! That watch’s light was instrumental in achieving all those things, and more! It was fabulous! I don’t know what happened to that watch; but I have really missed it through the years. Recently, I’ve experienced various needs for a digital watch. I haven’t cared much for the big, bulky watches that are digital, as I am petite and have small bones; those bulky things take over my arm, and, quite frankly, they look ridiculous on me. Even though they are “women’s watches,” they all look like I borrowed my dad’s watch and customized the size of the band. Plus, I _really_ wanted a digital watch with a light — one that was feminine and classy, so that I could dress it up or down and wear it anywhere, if I wanted/needed to! I regretted more and more not knowing what happened to that watch from my junior high days, especially since I seem to have an aversion to “smart watches,” which seem to be the only thing close in size that would work on me. Then I found this little watch! I couldn’t believe that Casio still offers it! It looks just like the one I had in junior high school! It even said in the description that it has a LIGHT! I knew it was the right size for me! It has everything I wanted — ease of use … very easy programming … it has the date, a stopwatch, and an alarm, along with, of course, the time! Plus it’s lovely to look at, it could go dressy or casual, it doesn’t swallow my entire arm, its band is adjustable [though it wasn’t easy to adjust — I had to get a guy to close it in place for me, as I just wasn’t strong enough to close the clamp, myself], it’s very feminine, and it keeps PERFECT time! I was THRILLED that I had found my long-lost watch from so many years gone by; and, since both of my parents are deceased now, even though I was buying it for myself, it felt like my parents were buying it FOR me, once again, with all of that parental love attached to it! I couldn’t wait to get my perfect little watch in the mail! I LOVE this watch. HOWEVER, the description LIED — it does NOT have a LIGHT! That really bummed me out. The other thing that bothers me is that the alarm is SO soft that I cannot HEAR it! It must be a sound/frequency that only dogs can hear! It will NOT wake me up from a nap, nor will it remind me to take my next pill or anything of the sort! I can put it right up to my ear, and I absolutely cannot hear it [and I have EXCELLENT hearing]! It DOES _have_ an alarm FEATURE, though … unlike the LIGHT that the description said it had, but in fact it does NOT. I still love the watch. It makes me feel close to my deceased family. It brings back cherished memories. It looks lovely on my boney arm. [lol!] It’s elegantly tailored, beautifully feminine and quite versatile … so yes, I decided to keep it. More than anything, though, I wish it had that LIGHT! Casio has always had a superb reputation as a watch of quality. This watch holds up to Casio’s reputation. It really DOES keep PERFECT time! I would absolutely recommend this little watch to any female, who is petite like me, who doesn’t wish to feel like she's wearing a man’s watch, but rather wants to continue feeling like a female wearing a watch. If she wants something versatile and lovely to wear as a timepiece, that keeps perfect time, is digital, and has helpful functions, this little watch is as close to perfect as she can get … barring the fact that the alarm is worthless and THERE IS NO LIGHT! 😁. The biggest plus, though, is that it’s “all that” and its price is quite reasonable! It will never go out of style, either; it’s just an absolute classic! Nevertheless, if they ever make one of these [this exact style and size, that is] WITH a light again, you betcha I’ll go ahead and buy _that_ one, especially if they don’t raise the price of the watch! Oh — one little word of caution — the band CAN catch the “peach-fuzz” on your arm and pull those hairs, which can be very uncomfortable, not to mention annoying and downright painful. However, if you just adjust the band, you will find the right band size, and it will cease the torture! If you are considering this little watch, I say, “Buy it!” I love it. It looks beautiful, feminine, and elegant! You really cannot go wrong with this one. I just wish the description that is posted with this item would not publish the untruth that it lights up, when it, in fact, does NOT. Otherwise, it’s a great find. 😉

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. ***

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!

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!
