Must have for guys
Top notch packaging with top notch quality, got this for approx 6.5k with credit card discount and I would say that it is an absolute steal for that price. Can be worn for both casual and formal events, even on the ground. Do not give it a second thought.

Smaller than what you see in photos
1. Casio don't give a sealed box. So you'll be not sure if the product is already used & returned by someone. 2. Watch looks big in photos. But small in real. I've added size comparison with a CREDIT CARD. It looks cute and durable. Only issue I found is with the size. It's small. Even though the watch model is old, Year of Manufacturing is 2025. So, it's a latest manufactured product.

Tecti-cool Casioak Stealth Black
1. Looks: This watch has a cool tectical look which looks amazing in daylight. But at low light conditions it almost becomes invisible 😅 and the dial is very difficult to read as the dial is black and the glass is a bit reflective. In these situations, the light comes very handy. 2. Wearability: Very comfortable to wear as it's just 51 grams and the resin strap quality is also good. The watch fits perfectly in my 9 inch wrist. It's very easy to use and requires zero care. 3. Value for money: Most critically acclaimed casioak at affordable price. The price ranges from 6k to 9.2k depending upon the offers. 4. Durability: Hands down one of the most durable watch money can buy 💯. Only thing is that the glass may catch a scratch or two. That's it. 200 m water resistance, casio carbon fibre core, shock proof, somewhat fire proof too.

Great Product from Casio
Casioak is one of the best and practical sized watches to wear. Being G-Shock, it's tough , durable and lightweight. It's super comfortable and goes well with sportswear. Casual wear and even on dark colored formal wears.

Relógio incrível.
O relógio é original, vem na caixa com manual, garantia e etiqueta. Chegou rápido e bem embalado. Estava doido para comprar um CasioOak, pois estou iniciando minha coleção e creio que toda coleção deva ter um G-Shock, justamente aquele relógio robusto, que vai durar anos, para utilizar quando for fazer exercícios, nadar ou até mesmo sair para um local mais arrumado, já que é um relógio incrivelmente bonito. Tive dúvida entre esse e o clássico DW5600 full black, mas achei esse mais bonito e moderno. Estava com medo do tamanho, já que suas dimensões são grandes (48.5 × 45.4 × 11.8 mm), no entanto, ele aparenta ser muito menor pessoalmente. No meu pulso de mais ou menos 16cm (6 polegadas) de circunferência, ficou ótimo, melhor até do que aparenta nas fotos, pois nelas parece que ele ficou grande, mas pessoalmente o efeito gerado não é este. Aliado a isso, é um relógio extremamente leve (51g), nem parece que você está usando. Gostei do preço que paguei (659 reais), já que nos EUA ele está a venda por 100 dólares, o que, ao converter e adicionar valor de impostos, sairia uns 600 reais. No site oficial da G-Shock Brasil ele é ainda mais caro. Como ponto "negativo" do relógio, é o fato de ele ser muito escuro, ruim para ver as horas à noite ou em ambientes escuros, embora ele tenha o LED para acender a parte digital. Porém, eu já sabia disso e comprei mesmo assim, não estou arrependido. Para mim, essa versão all black é a mais bonita da linha em resina, embora o relógio com a caixa em metal seja, para mim, o GA2100 mais bonito, porém não compensa pelo preço salgado de quase 2.000 reais.

Waterproof! I Went Full Aquaman to Find Out
After triple-checking online that my G-Shock was waterproof, I figured—why not test it the old-fashioned way? First dunk was caught on video, and since then it’s survived pool splashes, ocean waves, freshwater dips, chaotic family events, and even elegant dinners where it somehow still looked the part. No complaints, just compliments. The all-black look is sleek and stealthy—though maybe a little too stealthy at night. If your eyesight’s not 20/20 and your glasses are MIA, you might find yourself squinting like you're decoding ancient runes. But hey, that’s a me problem. Overall, I love this watch! Tough, stylish, and reliable. Already eyeing another one with bigger, brighter numbers for my midnight adventures.

Produto excepcional, superou minhas expectativas. Muito confortável, leve e ainda mais bonito pessoalmente. O único problema que tive foi com a entrega, que foi adiada 3 vezes.
