Casio Gwg
This is a crucial feature for this type of watch that ensures perfect legibility at all times, even in complete darkness. A clever function that Casio has incorporated is that if you press the light button and the lower-left button, the hands move out of the way for the screen so you can read it properly in case they are in the way. The resin is raised for the bezel in order to keep the screen protected, and both sides have ”bumpers” in order to increase its resistance to shocks, but also keep the crown and triple sensor protected. Casio has constructed the case from a plastic material and on top sits a sapphire crystal.
I have read in one of the answers that few models are ion plated. I do construction work and I’m an outdoors type person so far it has held up good. I don’t believe I will mess it up on the construction site. Only complaint is that the rubberized plastic g shock watch bezel has a matte black finish because of its size it rubs on the inside of my jacket sleeve. Now it is becoming shiny in spots that come in contact with long sleeve clothing. So basically the matte finish is getting a Polish from clothing.
This is just one of the many benefits of the carbon fiber-based frame. There’s little chance of a button being dislodged, even under the most severe impact. Casio’s G-Shock line of affordable, durable and all-around everything-resistant watches has been going strong for the better part of half a century. G-Shock watches are well-built, durable, and stylish in a do-everything, take-no-prisoners, vintage kind of way.
The case is made of high-rigidity carbon material to protect against damage and deformation due to impact and other rough treatment, while metal button pipes ensure a tighter seal against the external environment. A filter further protects against the invasion of mud, for the high level of dust and mud resistance required when in severe environments. In addition, the dual back cover consists of a stainless steel panel back and an outer cover made of shock resistant fine resin embedded with glass fibers. With a name like “Mudmaster,” you know that this is a watch that isn’t afraid to get dirty. Its massive 55 mm case makes room for a ton of structural engineering that its name suggests, starting with a Carbon Core Guard structure that protects its movement and its modules with a carbon fiber reinforced resin case.
The lower-left button on the left opens the list of the features on the watch’s LED strip, which you can access or customize with the help of upper-left button. The list of features includes timer, stopwatch, alarm, atmospheric pressure, temperature, etc. The thermometer can give readings in either Celsius or Fahrenheit. The watch’s dial is illuminated by a LED light and is protected by a sapphire crystal, which as per Casio cannot be scratched. It also ensures high visibility under virtually any conditions imaginable.
