  • Product Description
    Product Specifications

    Casio is an electronics manufacturing company that was founded in 1946 by Tadao Kashio. The brand has a versatile portfolio, from musical instruments and digital cameras to analogue and digital watches. The company raised to popularity quickly after releasing its first-ever product, a cigarette holder, which proved to be a huge success. Casio became involved in electronics in 1954 when they released Japan's first electro-mechanical calculator.

    During the “Quartz Revolution” in the 1970s, Casio expanded and became one of the first brands to create quartz watches which solidified the brand as an innovator in horological society. The brand’s timepieces are affordable and long-wearing, making them a favourite to both enthusiasts and everyday people. With the large variety of wristwatches and their commitment to progress, it is no surprise Casio has remained amongst the giants in the industry. 

    Core Features of the Casio G-Shock Mudmaster:

    • G-Shock watches are water-resistant over 10 bars or 100 meters.
    • The hands and the indices of the models are luminescent with Neobrite coating.
    • Incredibly durable, the watch is shock-resistant, vibration resistant and centrifugal force resistant.
    • The bezel of the watch has a herringbone print with a chrome finish
    • Casio’s G-Shock Mudmaster can be paired with a smartphone.

    Model Specifications: GG-B100-1A9ER

    • The black 53 mm case of the watch is made of carbon-reinforced resin.
    • An orange resin strap secures the watch.
    • The complicated dial gives the watch its distinctive utilitarian appearance. The dial features orange detailing.
    • A hard glass mineral crystal encases the dial.
    • Amongst the many functions featured on the watch are alarms, a calendar, altimeter and barometer, a compass, an LED backlight, a step counter and stopwatch functions alongside a sunrise/sunset function and a world timer.

    Customer picture of Casio Carbon Core MudMaster | Stopwatch | Bluetooth GG-B100-1A9ER Outstanding watch. I have had G-Shock watches for a number of years. Have been looking for a new one to upgrade from my previous one. I spent quite a while looking and found First Class Watches to be the cheapest and easiest to order. The watch arrived extremely well packed and arrived as promised.

    Really nice watch from Casio, great that we have a a Mudmaster with Bluetooth technology now. Very comfortable to wear and has all the functions you expect from a G-Shock. My only slight gripe is that this new model isn’t solar powered, which at this price point I would’ve expected.
    Usual very efficient service from First Class.

    Customer picture of Casio Carbon Core MudMaster | Stopwatch | Bluetooth GG-B100-1A9ER Well, what to say about this watch... other than it is pretty awesome!

    I have a few G-Shock watches now, ranging from the tiny Pikachu Baby-G to the beast that is the GWG-1000 MudMaster, the GG-B100 sits on my wrist more than the others now and is very worthy of the MudMaster name. It shares a lot of the features with it's big brother but has plenty more on top, in some cases it even betters its brother! For example, the barometer function, this watch can show you over 2 days worth of data (the GWG only shows 1 day), much better to see changes in the weather. I also find the thermometer to be better as you don't have direct contact with a metal case back as it has a resin cover. Then of course there is the step tracking function that can record your daily steps when using the G-Shock app on your phone. And when you do pair up with your phone a whole new bag of tricks is opened up for you.. from regular timekeeping updates to being able to record your location and then finding your way back using the watch, showing which direction and how far away, without having to take your phone out of your pocket/rucksack. Not to mention how much easier the app makes setting nearly all of the watch functions. I suppose I had better talk about how it looks.. I chose the orange version (1A9ER iirc), it looks stunning, then again all 3 versions do. It fits in nicely with the MudMaster range but slightly smaller than it's big brothers and the carbon fibre bezel looks very swish, the glass is domed which helps with any sunlight reflecting. Lume is pretty good, but should you need more light, the led light is amazing, it is literally the equivalent of shining a torch on the watch face! Fit wise, I have 8 inch wrists and the strap is plenty long, long enough that the tail end can still be held neatly down by the keeper. I barely notice the weight on my wrist, it is very comfortable to wear.

    tl;dr .... buy it now, it is awesome... oh and delivery was top notch, next working day and VERY well packed! Thanks!
