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.

Este es un clásico con todas las letras. La mejor opción para un primer reloj o simplemente para tener en una colección, incluso para ser el único reloj de una persona. Todos sabemos de su fama, y si a alguien le llama la atención, no hay por qué dudar. Personalmente, el negro original nunca me encantó tanto, y aunque era bonito, fué el azul que desde el primer momyque lo ví dije "será mío", lo he comprado dos veces porque antes lo vendí pero realmente se extraña, eso sí, como punto negativo es la correa que trae, para empezar, es negra aún en el modelo azul y luego, es de calidad cuestionable, el reloj es calidad máxima en el rango de precio, pero la correa es a penas mejor que el de un Casio CA-53 o un AE-1000, siendo relojes de un tercio de precio, así que es casi obligatorio cambiar la correa y por tanto, es un gasto extra a un reloj que antaño era facil de conseguir por al rededor de 45usd pero que hoy en día está regularmente sobre 80usd. Yo le cambié a un brazalete de acero que tenía desde hace tiempo y compré el reloj en $1,169mxn(unos 60USD), precio por el que es perfecto, pero si se paga un poquito más, la realidad es que no decepciona nada. No hay mucho más que decir, las imágenes hablan por sí mismas, una carátula sencilla pero maravillosa, perfecta legibilidad, una fecha muy discreta, excelente bisel, aunque en el caso de este esta ligeramente desviado y no coinciden al 100% los índices, cosa que se entiende, es casi imperceptible pero a algunos puede molestar mucho. Corona roscada, el marlin aún grabado en la tapa trasera, un empaque muy sencillo y correa para cambiar, pero en cuánta sus acabados, perfecto por el precio adecuado. Dimensiones perfectas para prácticamente cualquier tamaño de muñeca, si bien es un reloj grande de 44mm, los disimula muy bien por su distancia entre asas tan corta de unos 47mm, así que el reloj viste como de 42mm para algunos de muleca grande o mediana y se verá de 44 para muñeca pequeña, perfecto para muñecas de 17cm(tal vez incluso menos). En mí caso, mi muñeca es de 18cm y uso relojes de hasta 45 cómo máximo.

Good and reliable quality. Satisfied.

Superbe montre, belle, fiable, étanche ( à 200m!) et solide: Qualité Casio! Le tout pour un prix serré Elle a mis un peu de temps à arriver des USA, pour cause de délais de dédouanement, mais j'étais informé régulièrement de son statut. Je possède également le modèle identique sans le marlin et donc encore moins chère, que j'avais malheureusement rayé dans une chute de vélo à laquelle mon poigné, lui, n'a pas résisté. D'où ce nouvel achat. Merci Amazon!

ビルゲイツ愛用で有名な時計。子どもが欲しがり誕生日プレゼントに購入。シンプルで試験の時も使えるし、ダイバーウォッチなので濡れても大丈夫なのも嬉しい。

Relógio é muito mais bonito do que nas fotos. Parece muito mais caro do que é. Relógio honesto, bonito, de presença. E um clássico em extinção, porque essa versão com o peixe Marlin saiu de linha e não fabrica mais, está cada vez mais escasso, e por isso o preço só sobe. Quando os últimos estoques forem vendidos, já era, quem tiver vai ter uma raridade no pulso! Instalei uma pulseira metálica jubilee comprada na AliExpress que elevou ainda mais o relógio!
