Description

From G-SHOCK, the watch that always strives for toughness, the first G-STEEL lineup models to offer chronograph performance in analog format. Thought all the dials of these models are analog, they still boast G-SHOCK level shock resistance. The dial at 9 o'clock has a multi-functional rotating disk that is cut to resemble the thick blades of a jet engine. Rotation of the blades reveals red coloring behind the disk, and this change in color is used to indicate the battery level and the alarm on/off setting. The blades also rotate in the Timekeeping and Stopwatch modes to with the passage of time. A new layer guard structure houses resin cushioning parts inside the case, for a more elegant design and a better fit to the wrist. High density mounting technology makes it possible to create a module that is smaller and thinner, which also contributes to a better fit. These watches are equipped with Bluetooth that lets them connect with a smartphone at the press of a button, and acquire time information from an internet time server. The result is accurate timekeeping no matter where in the world you happen to be. Other functions include Tough Solar in combination with CASIO original power saving technology for a stable supply of power, high brightness LED light illumination, and dual dial World Time.

  • Very cool looking and durable watch
This watch easily survived a trip around the world. It has a cool feature where it syncs to your phone, so whenever you changed time zones, the watch automatically updated itself to the correct date and time. Pretty neat feature.

  • Not a fragile watch
Let me start by saying this is not a fragile watch like Apple Watch or Samsung frontier Both of these i own and broke both of them this is not a smart watch and it’s also not a small watch so far I love the durability and accuracy of the watch we’ll see how overtime it holds up I’m new to Solar watches and this one is a little hard to tell what kind of charger has on it The app is convenient for setting all the functions but no where in the app does it tell what level the charges is well hopefully at some point they’ll change this and will be able to get an accurate measure of charge I would buy this watch again in a heartbeat and if you work hard and play hard this watch will probably survive it ... show more

  • This is a winner!
Omg this thing is beyond beautiful. I’ve never been more pleased with something seen online and the actual product. Has some smart features like the ability to set multiple times and alarms through an app but it is far from a smart watch because it isn’t one! It just has a few upgraded features, and it doesn’t claim to be a smart watch, so don’t complain (I’ve seen some complaints about this on a couple YouTube videos I’ve seen). This thing looks like it’ll last a lifetime comepared to “smart watches” that will be old tech in 1-2 years. This is a great investment. You get that G-shock toughness with a classy touch. If someone sees you with this on, they know you mean business. I could totally see Dwayne “The Rock” Johnson wearing this watch, that’s how tough it is! BUY THIS WATCH! ... show more

  • Excellent Piece
I have hairy arms and it catches often under the case, but it is easily resolved with positioning and care. The crown was a bit stiff at the start and I am not the biggest fan of setting the watch via the Casio app. I have to say that I am being a bit critical though. The watch is excellent. I’ve banged the crystal a few times and no scratches. I enjoy the features, the bezel holds up to my everyday, outdoor use and it has excellent movement for the money. This was well worth the purchase. ... show more

Maybe it's too early to tell but this watch is magnificent so far I love the look and factuality the bluetooth capability makes it the perfect watch for today

  • Really a fantastic watch!
The GST B100 is an elegant watch, although on the larger size. Has 300 city world times, alarm (although, this particular watch only has one daily alarm, but not an issue for me) stop watch, timer... and best of all, Tough Solar! G Shocks are really amazing watches... many work on solar, so you never have to worry about replacing the battery or resetting the watch, many have atomic solar for incredible accuracy, this particular watch uses bluetooth to link to your cell phone, and get the exact time off of your phone! Solid, well built, numerous functions... does it sound like I love this watch??? Well... I do! Well worth the price! Casio has hit a home run! ... show more
