Its iconic octagonal shape pays homage to G-Shock’s roots while delivering a sleek, modern profile that fits seamlessly from boardroom to weekend adventure.

## Description

Carbon Core Guard structure: Ever since the first DW-5000C went on sale back in 1983, G-SHOCK has continued to push the limits of timekeeping toughness while creating new and original designs. These new models embody these efforts in an attractively thin configuration. These new models inherit the octagon form that was also employed for the original DW-5000C. Analog-digital timekeeping comes packed into a no-nonsense simple design without sacrificing G-SHOCK level toughness.

### ⭐⭐⭐⭐⭐ Great Product from Casio

### ⭐⭐⭐⭐⭐ Decent Watch. Looks quite graceful.
*by T***. on 5 October 2025*

I bought it for my son, he's very happy. Especially size & shape of this model is perfect. It doesn't look bulky like few G-Shock models.

### ⭐⭐⭐⭐ Tecti-cool Casioak Stealth Black
*by A***N on 8 September 2024*

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.
