## Overview

The Casio G-Shock GA-2100-1A1DR is a cutting-edge analog-digital watch featuring a durable carbon core guard resin case, 200-meter water resistance, and precise quartz movement. Its iconic octagonal design pays homage to the original DW-5000C, while its lightweight 51-gram build and dual time display make it the perfect blend of style, comfort, and rugged functionality for professionals on the go.

## 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.

Review: 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.
Review: 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.

### ⭐⭐⭐⭐⭐ Great Product from Casio
*by R***L on 30 November 2025*

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.

### ⭐⭐⭐⭐⭐ Smaller than what you see in photos
*by D***J on 2 April 2026*

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
*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.
