The G-Shock G100-1BV utilizes a Quartz movement with an accuracy of plus/minus 15 seconds per month.

The Good

There are an incredible amount of positive elements in this Casio G-Shock design. First, the shock, water, and magnetic resistance are features that you will only find together in a watch such as this.

The rugged Resin case and bezel is incredibly durable and built for withstanding exposure to the elements, falls, and rough living.

Excellent features of this model include an EL Backlight with Afterglow, Dual Time, Daily Alarm, 1/100 Second Stopwatch, a pre-programmed Auto Calendar (good until 2039), 12 and 24 hour format display options, 200 meter (660 feet) water resistance, magnetic resistance, and shock resistance.

The triple black design looks great with the red and white accents of the hour indices, luminous dial hands, and etchings into the bezel.

The dual Analog-Digital display of this G-Shock is perfect for keeping track of the chosen features, mode, and time options.

The Bad

This 47.8mm G-Shock is magnetic resistant and is designed and built to withstand magnetic force. However, you should still keep it away from appliances and machines that generate a strong magnetic field just in case. This is because exposure to strong magnetism can cause timekeeping to slow down, which affects accuracy.


One of the highlights is the “resistance factor.” This G-Shock has it all: shock resistance, magnetic resistance, water resistance, and a strong mineral dial window for the best protection against the elements in different weather conditions and temperatures. The sheer durability of the Resin case and bezel, as well as the Resin band, make this a watch that can withstand the force of nature.

The triple black design is also very attractive and bold with the red accents, white etchings and dial markers, and luminous hands, as well as the EL Backlight with Afterglow. There isn’t a situation one can think of where this G-Shock would not be useful.


The functionality of this timepiece is nearly perfect. With a Quartz movement and a battery that lasts for a minimum of 3 years, you can expect top notch quality and performance out of this G-Shock.

With its famous shock resistant Resin construction and water resistance, you can take this rugged watch to any event, sport, extreme sport, or adventure you put your mind to.

The special features are also excellent, with options for keeping a calendar, setting alarms, viewing dual time, using it as a stopwatch, and more.

The EL Backlight with Afterglow is perfect when the sun sets or when you are in the water.


You can purchase the Casio G-Shock Men’s G100-1BV model on Amazon.com for 45% off of the $99.00 retail price. For only $55.00, you can purchase one of the best G-Shocks available.
