Casio G-Shock MTG-B2000: An In-Depth Review

The Casio G-Shock series is one of the most well-known collections in the horology industry. Known to both watch enthusiasts and casual wearers who are not familiar with the watch market, the Casio G-Shock is highly regarded for its hefty build and robust durability. In particular, the Casio G-Shock stands out for its use of resin, which gives it a superior degree of shock and impact resistance. 

Of course, a brand like Casio is nothing if not adventurous. As such, in 2020, the brand diversified its G-Shock range with the release of the Casio G-Shock MTG-B2000. Despite belonging to the G-Shock collection, these G-Shock MTG watches break from the norm with their sleek metal cases and high-quality finishes. Promising style and ever-reliable levels of shock resistance, the Casio G-Shock MTG is the G-Shock collection’s newest premium line. 

Without further ado, let us delve deep into the Casio G-Shock MTG and everything it has to offer. 

All About Casio G-Shock MTG B2000

The first Casio G-Shock MTG watches were introduced in 2018, under the moniker Casio G-Shock MTG-B1000. Despite being the newest additions to a collection known for using resin materials, the G-Shock MTG line distinguished itself by incorporating unprecedented levels of metal into its watches. These watches managed to show off more lustrous aesthetics, while still maintaining the level of shock resistance expected from G-Shock watches.  

Thanks to the popular reception of the G-Shock MTG-B1000 timepieces, Casio decided to release newer, upgraded variants of the G-Shock MTG. Most recently, in September 2020, the brand unveiled its G-Shock MTG-B2000 watches. These latest iterations of the G-Shock MTG promise more stylish designs and updated features that can only be found in Casio’s top-tier models. 

Casio G-Shock MTG-B2000: First Impressions

Right off the bat, the Casio G-Shock MTG-B2000 is still recognizable as a distinctively G-Shock piece, with its rugged and outdoor-ready build. It is a revamped version of the G-Shock MTG-B2000, with similar dimensions and a slightly busier dial. 

One significant upgrade that has been made to the G-Shock MTG-B2000, however, is its bezel. As opposed to the MTG-B1000’s round case, the MTG-B2000 shows off a rare dodecagonal bezel, tailored to suit shock-resistant watches like this. 

Thanks to this bezel, watch fans have remarked on the MTG-B2000’s resemblance to other watches with angular bezels. This has led to very flattering comparisons with iconic pieces like the Audemars Piguet Royal Oak and the Patek Philippe Nautilus. As a result, the MTG-B2000 possesses a versatility that makes it an interesting choice as a dress watch for formal occasions too. 

Anatomy of the Casio G-Shock MTG-B2000 



The Casio G-Shock MTG-B2000 comes in a chunky 55.1mm case that measures 15.9mm in thickness. Although it is slightly smaller than its MTG predecessor, this watch still poses a very significant presence on your wrist, a trait that is true of all G-Shock watches. Like the watch bezel, the case itself is twelve-sided, giving it a very sharp and angular look. 

The case of the MTG-B2000 shows off a very layered build, which contributes greatly to its durability. It is composed of a rigid carbon monocoque case and a firm stainless steel cargo frame, which protects the inner case from external shocks. The stainless steel frame is treated with a black IP finish and a lovely Sallaz polish. This gives the frame a sleek, mirror-like black surface that adds to the visual appeal of this watch. 

The use of carbon is critical in the MTG-B2000, as it is both highly shock-resistant and can be molded into complex shapes, offering greater design freedom. Since carbon is very lightweight, its use also ensures that the G-Shock MTG-B2000 does not weigh too heavily on your wrist. Thanks to the case’s semi-carbon composition, the MTG-B2000 weighs just 156 grams in total, which is quite light considering its size. 

The case is also equipped with the brand’s signature Triple G Resist system. A major factor contributing to the G-Shock watches’ durability, it reinforces the MTG-B2000’s ability to withstand shocks, centrifugal forces, and vibration. In addition, the MTG-B2000 also has a solid depth rating of 200 metres, so you can easily bring it for a swim.

As we mentioned, the bezel is also a highlight of the G-Shock MTG-B2000. This bezel has an unusual dodecagonal shape. It is crafted entirely from stainless steel, so it is very robust and protects the watch face from any scratches or impacts. 

The bezel is also treated with a layer of ion plating. This further boosts its resistance to scratches while also giving it its shiny pink-red hue.

The G-Shock MTG-B2000 comes with a three-link stainless steel bracelet. Like the watch case, this bracelet has been treated with a black IP finish and Sallaz polish. In order to reduce the heftiness of the MTG-B2000, however, Casio has hollowed out this bracelet to make space for metal injection moulding. This reduces the overall weight of the MTG-B2000’s bracelet to 15% less than a typical, all-stainless steel strap. 

This metal strap is equipped with a double slide lever. This allows you to quickly wear or release it, maximising convenience. 

Aside from that, the MTG-B2000 is also offered with a soft urethane strap in black. If you want your MTG-B2000 piece to be even lighter, then this urethane band is a great choice. With the urethane strap, the MTG-B2000 weighs 127 grams in total and comes at a slightly cheaper price tag. 



Compared to its predecessor, the Casio G-Shock MTG-B2000 shows off an improved dial configuration which allows for easier readability. It shows off a matte black finish that wonderfully complements the rest of the watch. 

This dial is also filled with oversized sword hands in silver-white and thick, applique hour markers that give this watch face a three-dimensional look. The hands and indices have been coated in Casio’s LumiBrite material, allowing for optimal legibility even in the dark. On top of that, this watch also comes with an LED backlight, which you can activate using one of the pushers on the side of the case. 

As a chronograph watch, the G-Shock MTG-B2000 also contains three sub-dials in different sizes. The sub-dial at 8 o’clock serves as the 12-hour chronograph counter, while a smaller day-night indicator is placed to the right of it. At 3 o’clock, you can find the day-of-the-week and mode indicators. Finally, a 24-hour display is placed on the upper left hand of the dial. Metallic red accents are also scattered all around this watch face, matching the bezel and giving it an especially cool look. 


Underneath this packed dial, you can find an in-house Japanese Seiko quartz caliber. This is a Tough Solar movement, which means that it can be charged using any form of consistent light source, artificial or natural. When fully charged, it can last for up to an impressive five months without any exposure to light. 

Dual Core Guard Structure

One of the core features of the Casio G-Shock MTG-B2000 is its Dual Core Guard Structure. This is an improved version of the Metal Core Guard Structure, which was first introduced in the MTG-B1000. 

The Dual Core Guard Structure accentuates the aesthetics of a metal watch without the need to make it too big or bulky. It does away with the traditional metal caseback. Instead, the Dual Core Guard Structure employs a carbon monocoque case that seamlessly integrates both the case and caseback, making use of the strong yet lightweight nature of carbon. A metal frame is then placed around the case, offering it greater protection against external damage.

The Casio G-Shock MTG-B2000 comes with a number of useful Casio-developed systems as well. For instance, it is equipped with the brand’s Multi-Band 6 technology. This enables it to receive time calibration signals from six radio stations around the world, which allows for more accurate timekeeping. It also has Bluetooth connectivity features, so wearers can automatically sync up the watch’s time or change between 300 different timezones. 

Casio also developed a dedicated app for G-Shock watches, the G-Shock Connected, which the MTG-B2000 has access to. Using this app, wearers can check on the watch’s updates and data history or access alarm and timer settings. You can even use this app to keep track of your health stats through the watch. 

The MTG-B2000 supports operating systems including and above iOS and Android 7.0. 

Price and Availability

As the most luxurious item in the entire G-Shock lineup, the Casio G-Shock MTG-B2000 retails at a more exorbitant price compared to its peers. You can purchase it for around $1,000 USD. 

Final Thoughts

The Casio G-Shock MTG-B2000 is a truly unique G-Shock offering. It retains the collection’s signature rugged boldness. At the same time, it also incorporates a new stylishness through its metal framing, giving the MTG-B2000 a versatility that allows it to fit in both in the wilderness and in more formal settings. Without a doubt, the MTG-B2000 is the best that G-Shock has to offer.
