Casio G-Shock GMB2100 Full-Metal “CasiOak” Review

August 30, 2023

In 1983, Casio introduced the revolutionary line of watches known as G-Shock. Designed to surpass expectations, the G-Shock aimed to provide a battery life of a minimum of ten years, withstand water pressure up to ten bar (100m), and endure falls from heights of up to ten meters. Since its inception, Casio has successfully sold over one hundred million G-Shock watches worldwide, cementing its popularity among watch enthusiasts. Among the current collection, one standout model is the widely acclaimed “CasiOak,” renowned for its striking resemblance to Audemars Piguet’s iconic Royal Oak timepiece.

Crafted with meticulous attention to detail, the GMB2100 case boasts a sturdy steel construction enhanced by a sophisticated three-step surface-finishing technique. This meticulous process results in a distinct three-dimensional aesthetic that captivates the eye, adorning both the case and bezel. Notably, the top surfaces of the watch feature a captivating circular brushed finish, while the sides showcase an elegant vertical brushing technique.

The remaining areas of the watch embrace a polished style, providing a harmonious balance of textures. The brand achieves sharp detailing on the index and inner dial through a vapor deposition treatment, further enhancing the multifaceted allure of the timepiece. For discerning individuals, the GMB2100 is available in three exquisite case finishes: classic steel, black IP-coated steel, and copper IP-coated steel.

The new model of the G-SHOCK retains the impeccable craftsmanship and superior finishing seen in previous Full Metal editions. The latest model sets itself apart with a sleeker design that sits comfortably on the wrist. It measures only 12.8mm in height, making it thinner than its predecessors. In keeping with the signature “CasiOak” style, the watch maintains a well-balanced proportion with a 44.4mm diameter and 49.8mm length. Embodying the essence of the GA-2100 series, the GMB2100 features a captivating blend of analog and digital elements on its dial.

Positioned between 3 o’clock and 6 o’clock, a versatile digital window offers a range of functions. Complementing this, a subdial at 9 o’clock serves as a handy indicator for various watch features. The central analog hour and minute hands provide a traditional touch to this contemporary timepiece.

Driving the GMB2100 is the highly reliable Module 5691 quartz movement. This watch incorporates the innovative Tough Solar Technology, enabling it to convert even the faintest light sources into power. Furthermore, it boasts a power-saving mode for extended usage. The Full Metal watch has standard G-SHOCK technology in all three versions. It comes with a 24-hour stopwatch, a 60-minute countdown timer, a hand shift function, and a multilingual day of the week display. Additionally, users can swap the date/month display as per their convenience. As expected from the G-SHOCK line, this timepiece is remarkably resistant to shocks and offers an impressive water resistance of up to 200 meters.

Similar to its counterparts in the Full Metal collection, the GMB2100 introduces Bluetooth capabilities and incorporates Smartphone Link features through the G-SHOCK Connected app. This innovative technology enables the watch to seamlessly connect with smartphones, providing automatic time updates, convenient watch adjustments, timestamped location information, calendar reminders, and a useful phone finder function.

With its distinct octagonal bezel and ana-digi dial display, the GMB2100 joins the popular line of timepieces known as “CasiOak.” This nickname pays homage to the renowned Royal Oak, renowned for its sporty style, geometric shape, and resemblance to the iconic GA2100 design. The new Full Metal models continue to embody a modern sense of luxury while remaining considerably more affordable, exemplifying the original intention behind the “CasiOak” models. This launch further demonstrates G-Shock’s commitment to expanding its range of luxury-focused offerings, complementing the already impressive assortment of serial and limited releases within the extensive Full Metal and MR-G series, which is certain to be enthusiastically embraced by the brand’s devoted followers.
