Review: An excellent G-Shock! - Excellent G-Shock! The appearance is incredibly good, it screams "sporty" and "stylish" the dial looks like the speedometer on a Ferrari, if it didn't say "Casio" and "G-Shock" on it I would think it was a Ferrari brand watch. It is incredibly accurate and comfortable it gets a lot of attention and looks fantastic, the negative display can be a tiny bit hard to read at times but it's really not too bad and the light is good enough also to light up the hands. Another thing to note is that you can choose to either display the time or the date on the screens below the hands you cannot display both, this is a small issue as the hands will display the time regardless and if you change the time digitally? the hands will move on their own to adjust (Which looks so cool, trust me!) I could not recommend this watch enough! fantastic release from Casio! Review: A proper bloke's watch with a hint of gaiety - Perfect red with a satin matt finish. Lightweight & comfortable. I am blessed with 9 inches (of wrist size) & it fits on the last pair of holes but looks aok in the hasp & a millimeter of strap still comes through after the securing band is pulled round. Very easy to set up, the easiest Casio I have in fact. Bright silver digits in black LCD displays are perfect. One tiny issue, the hour hand is red with the minute hand white & this makes for a little extra looking to spot it. Only the red does this by the looks of other colours I have looked at. ## Features - item shape: Round water resistance depth: 200 m - World time - 1/1000th sec stopwatch - Repeat countdown timer - 5 alarms - 200m water resistant ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005FEY8YK | | Age Range Description | Adult | | Band Colour | Red | | Band Material Type | Resin | | Band Width | 22 Millimetres | | Bands | 1 | | Best Sellers Rank | 352,246 in Fashion ( See Top 100 in Fashion ) 2,529 in Men's Wrist Watches | | Brand Name | Casio | | Case Diameter | 51 Millimetres | | Case Material Type | Resin | | Case Thickness | 15 Millimetres | | Character | Fashion | | Clasp Type | Buckle | | Closure Type | Magnetic | | Crystal | Crystal | | Customer Reviews | 4.6 out of 5 stars 1,778 Reviews | | Dial Color | Black | | Display | Analog-Digital | | Face Style | Classic | | Included Components | 1 package | | Item Part Number | GA-100B-4AER | | Item Shape | Round | | Item Type Name | Watch | | Item Weight | 70 Grams | | Manufacturer | CASIO | | Manufacturer Part Number | GA-100B-4AER | | Manufacturer Warranty Description | 2 years | | Material | Resin | | Model Name | GA-100B-4AER | | Model Number | GA-100B-4AER | | Model Series | G-SHOCK | | Number of Items | 1 | | Number of Packs | 1 | | Pattern | Solid | | Power Source | Battery Powered | | Special Features | Alarm, World Time, countdown timer, stopwatch | | Sport Type | Other Sports | | Strap Type | Plastic strap with buckle | | Style Name | Sport | | Theme | Bracelet | | Unit Count | 1 Count | | Warranty Type | Manufacturer | | Watch Movement Type | Quartz | | Water Resistance Depth | 200 Metres | | Water Resistance Level | Waterproof | ## Images ![G-Shock Men's Watch GA-100B - Image 1](https://m.media-amazon.com/images/I/61pRVXJThHL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: dose this model have date and month as it say it do not and is the size 55 as it said thank you** A: Dear Tanto,Thank you for your e-mail.

Lightweight & comfortable. I am blessed with 9 inches (of wrist size) & it fits on the last pair of holes but looks aok in the hasp & a millimeter of strap still comes through after the securing band is pulled round.

I have purchased the red colour version and have been very pleased with it since day one. The watch is very accurate and it also comes with a small amber LED light to see the time at night (I know some reviews said the LED is poor but my honest opinion is it does the job and you can see the time in darkness). The watch is totally water proof and cold weather proof. I have done a weather test myself by leaving it in a bucket overnight as well as leaving it inside my freezer for 24hr. The watch survive in both tests and I have attached photos for your reference. Very happy with the product and I would definitely recommend it to anyone who is looking for a sporty looking, strong and reliable watch. ## Frequently Bought Together - Casio G-Shock Men's Watch GA-100B - CASIO Mens Analogue-Digital Watch --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/47919598-g-shock-mens-watch-ga-100b](https://www.desertcart.com.sa/products/47919598-g-shock-mens-watch-ga-100b) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-09-30*
