Waterproof Diving Watch. Do not expect to every watches can be waterproof or water resistant.Even if your sports watch maybe a waterproof feature on the dial or even the back cover. But you also have the capability of it. Sometimes it may help you to sweat, dust or rain water only and probably is water resistant in different situations.

Casio Men’s G-Shock G100-1BV Classic Ana-Digi Watch

Casio Men’s G-Shock G100-1BV shock resist watch,has remained consistently popular. It makes me feel that this is the classic version, which fans of Casio must have. If you work or an extreme activity, the watch that will go with you anywhere and at anytime, it would be tough. Of course, Casio have a good reputation about the durability, strength.

This watch is a good deal for the price, it's one of the more affordable G-Shock watches that you've got come across. It looks masculine on the wrist and contains the appearance of a military watch. The back light isn't highly bright and i also have remarked that many reviewers are disappointed with with the method by which you adjust the analog hands, It is quite hard to set the analog part, until you realize you hold down the set button.

So the buttons take time and effort to press, (To make sure they can't get pushed without trying.)
An interesting feature for me, Shock Resistant-Support men activities, 200M Water Resistant- No need to worry about water sports, Magnetic Resistant-Magnetic field will affect the mechanism of the clock but stop worrying about G-Shock G100-1BV, Backlight with Afterglow - Some people are not impressed with it but for me, it helped me a lot for dark environments. It may not be very bright, but it can glow all the time you press it. It is better to rely on the phosphor, which have a limited time to glow.

Overall: This watch has a very sturdy, slightly thicker than other digital watches (compared to the basic DW-6900), well built water-resistant watch, and possesses a decent amount of basic functions. It was great to watch everyone's satisfaction, affordable, and ideal for buying it as a gift to your loved ones.
