Overall Customer’s Feedback

The traditional Japanese hue known as Kachi-Iro is popular among customers (winning color). The winning color Kachi-Iro – a dark navy blue with a long history in Japan, was chosen by samurai and was frequently used for armor and helmets. Therefore, it signifies that the spirit of the samurai warrior inspires the new MR-G model.

Furthermore, the nicest feature that has received positive feedback on the watch is the Connected Engine 3-Way module. This indicates that the MRG-G2000HA is equipped with GPS, terrestrial radio waves, and Bluetooth connectivity. As a result, it enables the watch to receive receptions (either automatically or manually) for time calibration and connect to the app on the phone for additional features.

In-Depth Review of Casio MR-G Watches

Size & weight

The watch weighs 16 ounces. This is an average weight for a regular Casio G-Shock Watch. Plus, with a diameter of 46.2 mm, this item appears to be pretty comfortable for watch users. However, if you have small wrists, you might want to move to other options since this model will be like a rock on your arm.


The watch’s case is made of deep-layered hardened titanium. It has a titanium bezel that has been recrystallized. The surface of this heat-treated titanium has a unique crystal pattern that is like Neon Japanese sword blades.

Water resistance

This G-Shock model has a water resistance of 200 meters. However, this does not imply that you can swim as deep as 200 meters below the surface for as long and as often as you like, and the watch will not malfunction. The ISO testing procedures are stringent, but they do not include someone diving 200 meters beneath the surface and confirming the time.

Instead, it’s a pressure test in a laboratory that’s comparable to static water pressure, followed by a one-hour immersion in 40 centimeters of water. The official unit of measurement is the atmosphere (ATM), which equals 40 meters of static water pressure.


Casio’s in-house quartz movement, the 5652, drives both watches. The 5652, like many G-Shock models, includes Casio’s Tough Solar charging system, radio-controlled time synchronization six times per day, a second-time zone, a 24-hour chronograph, a 24-hour countdown timer, one daily alarm, and a fully automatic perpetual calendar accurate through 2099.

The battery life of the 5652 is up to 26 months after a full solar charge. So don’t be concerned about the battery because it never seems to run out.



The watch uses sapphire crystal. This is not glass but rather a substance formed by crystallizing pure aluminum oxide at extremely high temperatures.

Sapphire crystals have a high degree of refraction. Furthermore, sapphire’s scratch and shatter resistance demonstrate its rank as one of the toughest substances on the planet. Anything harder than sapphire, on the other hand, can scratch it. 

So, as long as it doesn’t come into contact with a diamond or silicon carbide, you’re good. Scratched sapphire crystals, on the other hand, cannot be restored but it is replaced instead.


The dial is packed with traditional Japanese themes that are skillfully woven together with the high-tech ultramodern MR-G style. The main black dial surface is finished with an alternating triangular design known as Uroko, or fish scale, which can be found in centuries of Japanese art and craftsmanship.


Casio employs a black DLC coated version of the integrated three-link titanium bracelet seen on this model for a clean and cohesive look. The watch also features a black integrated fluorine rubber strap with a slight nod to traditional Japanese themes. This strap’s raised central section displays the classic Bishamon tortoiseshell pattern, emphasizing the relationship to samurai aesthetics while giving a punch of distinctive texture in earlier images.

Other special features

Recognizing that high-end G-Shocks can be difficult to use for beginners, Casio has integrated Bluetooth connectivity on almost all of its high-end versions. Therefore, customers can control and alter the watch’s numerous settings and capabilities more simply and conveniently using the G-Shock Connected app.

The watch has an alarm, a countdown timer, chronograph capabilities, and the ability to display time in two timezones simultaneously. It also incorporates Multi-Band 6 technology, which allows the watch to receive time calibration signals from six stations located around the world – two in Japan, one in China, one in Germany, one in the United Kingdom, and one in the United States.
