Bought as a gift for a young man, as an introduction to watches as opposed to his mobile phone. I needed something sturdy and waterproof, that would not need a lot of care and attention on a daily basis. This watch appeared to fulfill this whilst looking modern. Fiddle factor was also something i wanted so the included features were also a factor.

My Carbon G-Shock is certainly rugged, but there are situations calling for something both dressy and sporty. That’s where this watch comes in. All the ease of pairing it with your phone, functionality, digital accuracy with analog face, plus a steel case and bracelet. Can’t go wrong.

This is my first full metal G-Shock watch and I'm extremely impressed with the quality and how it fits so so nicely on my arm. The price was fantastic as was the communication and the postage was unbelievably quick. I will definitely be purchasing from Watch Direct again. Thank you!!
Great watch very pleased with first class watches. Fast posting, delivered within 2 days of ordering. Good website and watch is exactly as described. Nice big bracelet had to remove 2 links, and my wrist isn’t small.Once the Casio app is downloaded, setting the time is simple using my phone, not the watch! Amazing. Great watch, easy to use, built to last, forever.
I like the watch, great design, easy to set up everything using Bluetooth on your phone, but I would suggest to avoid setting the time, day, month and year manually, it's really inconvenient and confusing at the first sight. Even when you need to set the timer quickly, it's just uneasy, because using the crown is time consuming and unhandy. If you need something more functional where you can use timer and stopwatch easily it's better to choose mudmaster in this price range. Another minus is that you cannot turn off the sound when pressing buttons or maybe I just haven't found out yet.
I am very impressed by the service value and peace of mind that First Class Watches provide .i am happy to recommend them to my friends and family.The communication, shipping speed and price including shipping is the most competitive if all other sellers .The G Shock Steel is a really stunning timepiece perfect working functions great contrast of steel and resin already getting compliments and being asked where i bought it from and were suprised at the excellent value .G Shock Steel GST B100Overall a great smooth and easy transactioni will be buying more from them for gifts and for myself in the future .I would give 6 stars !Best regards to all at First Class Watches.Thanks againHarry .
After such a positive experience with the purchase of the GSTB200D though Rowland of first class watches I just had to come back again.The GSTB200D was the most beautifully, well engineered watch I had ever laid eyes on until now that is, when I held in my hand the GSTB100D!The watch screens luxury and tank tough at the same time. Being fully analogue it is similar and yet completely different to it's ana digital brother..Do I favour one over the other? Just purchase both..As expected the watch arrived in record time (5 days) in exceptional packaging. The service I received from Rowland was first class and was the main reason for me coming back for more so early on in the piece...Thanks again fellas... A job well done indeed!Now for what G to buy next.....
Great watch. Solar powered with 6 month battery life with full charge. Multi band six so picks up atomic signal from Colorado to set the time. Backlight is amazing on this model -- it is blue in color and lights up the back portion of the dial and the main white ticks at one, three, five, seven, nine and eleven. This also lights up the hands of the watch with very bright green edges on the hands. The hands also glow in the dark along with small ticks at each of the numbers on the dial. G-Shock protection, water resistant to 200M and mud resist. Black case with gray band. Very heavy duty. Hourly chime, 5 alarms, world time, stopwatch and timer. Super cool watch. MSRP from Casio tag is $300.00 USD.
Love having a watch that keeps perfect time, due to blue tooth connection with phone. Also no need to replace batteries as is solar charged. A jolly good purchase and the seller was good enough to send me parts of the strap to enlarge it. A smashing experience overall.

G-Shock G-Steel GSTB100-1A
This is a model from the G-Shock Mudmaster Series, designed for use in extreme environments scattered with rubble, dirt and debris, and uses carbon materials. The use of high rigidity carbon on the case keeps damage and deformation at bay, and ensures a high level of airtightness and shock resistance. This model also features a filter that protects against the invasion of mud, a stainless steel panel back, and a back cover made of shock-resistant fine resin embedded with glass fibers, giving it a high level of resistance to dust and mud. The bezel also uses three layers of fine resin with carbon fiber inserts and is designed to resemble a portable gasoline can that could be found on off-road vehicles. Function-wise, this model comes with compass, altimeter/barometer, temperature reader and pedometer. In addition to being able to easily correct the time using the dedicated CASIO WATCHES app, there are lots of other useful features including the Mission Log feature, which automatically records in the app altitude data obtained from the watch and route data obtained by your smartphone. This is a toughness watch that supports you in taking quick decisions and accurate actions.
