G-Shock MT-G Buyer's Guide

We've come a long way since G-Shock inventor Kikuo Ibe dropped the first of his humble prototypes out of a windowed bathroom high above the pavement at Casio headquarters – just to see if it would survive. If you're unfamiliar with the story, don't miss Rob's adventures in Japan touring the Casio manufacturing and R&D facilities, documented previously on the Topper Blog.

36 innovation-filled years since that fateful experiment has led us to the MT-G collection (short for "Metal Twisted"), a strikingly modern, but mature collection of premium G-Shock watches that marry brains with brawn, while still bearing all the hallmarks of classic capability that G-Shock fans have come to demand. Now through the end of August, we're delivering more value than ever on the MT-G collection, with a Topper-exclusive special reserved just for our collecting community. You can learn more about that promotion right here, or read on to learn more about the three most important tenets of the MT-G collection.

As mentioned, the 'MT' delineation in the MT-G title stands for 'Metal Twisted,' which speaks directly to how each watch in the collection twists stainless steel around an ultralight carbon fiber-reinforced inner core, which houses the module and other sensitive timekeeping elements. Just like the G-Shock that Mr. Ibe tossed out of a window 36 years ago, the highly sophisticated MT-G watches still adhere to the same basic principles of shock resistance, water resistance, and self-sustainability, the latter of which is represented in the modern MT-G watches in the form of solar power, radio-controlled timekeeping, and Bluetooth synchronization.

Unlike a standard digital G-Shock, or even a lightweight 'Master of G' offering, the MT-G watches deliver a more tactile wrist presence, thanks to their unique hybrid alloy construction. But unlike even the larger resin-cased Master of G watches, MT-G cases have been specially designed with ergonomics in mind, deploying smaller movement modules to yield more moderate case sizes, fitting lightweight alloy cases with hollowed-stainless steel bracelets, and engineering lugs that articulate their straps around the tops of the wrist for greater wearer comfort.

Premium hand-finishing – the likes of which you might see on a high-end watch of both Swiss or Japanese origin are also introduced to the MT-G line. Here, Sallaz polishing techniques are executed by highly trained craftsmen to produce brushed, or super-smooth, mirror finishes that neatly contrast more rugged elements, like crown knurling and honed screws throughout the watch.

The premium treatment continues throughout the dial, where you'll see the depth and texture we love about higher-end G-Shocks, but with a series of additional premium flourishes, like laser-engraved indexes and hands – which are fully luminous and legible in low-light, but enhanced with a super-bright LED that floods the dial with light at the press of the pusher at 2:00. Speaking of buttons, the MT-G looks complicated, but the movement is actually quite user-friendly: the 'mode' button at 8:00 jumps between its various functions (stopwatch, countdown timer, alarm), and then the 'light' and 'receiving' buttons at 2 and 4:00 respectively activate, and reset each function. Many of the hands on the dial pull double-duty, snapping to laser-engraved indicators on the dial's periphery, or whizzing between 'home' time and the  chronograph's elapsed time. To enable the quick, independent actuation, each set of hands is controlled by its own motor at the heart of the Connected Engine module (5544).

The MT-G watches are perfect for frequent travelers as well, as the times in two different cities are displayed on the main dial and via the subdial at 6:00 (which has a companion AM/PM indicator just to its right). Both of these times can be quickly set using the watch's companion app, and regularly synchronized via Bluetooth for incredible accuracy, no matter where you are in the world. The app also displays information that's non-essential to timekeeping, like reception status, a solar power generation status (though there is a solar power reserve indicator tucked into the 9:00 subdial, and the battery's charge level can be displayed by cycling through the functions), and internal data updating history are all displayed with a series of graphics, creating a neat tie-in between both the analog, and the digital age.

The most emblematic variant in the MT-G collection is probably ref. MTGB1000D-1A which delivers striking contrast between this signature MT-G case, dial, and bracelet (though it’s also available on a black rubber strap in reference MTGB1000-1A). It’s here where you can best see the impressive range of finishing techniques deployed throughout the case, which contrast the many varying depths and textures found throughout the dial and perimeter of the case – all details that make the MT-G watches so fun to wear. The rest of the references in the collection utilize the same 55mm case (51mm lug-to-lug, and 14mm thick) and Connected movement module, in a variety of case finish and strap combinations, which include a black IP-coated case with red or black rubber straps (ref. MTGB1000B-1A4 and MTGB1000B-1A, respectively). All the aforementioned feature bright red accents, but there is a dramatic blue-accented variant, in reference MTGB1000BD-1A which has a black IP-coated case and bracelet with blue anodized subdials.
