I want these! 5 noteworthy G-SHOCK and Oceanus models

　Casio celebrates the 50th anniversary of its entry into the watch business in 2024. In 2025, the company will continue to release many new models from its diverse brands. Among them, the brand's first mechanical watch, released under the "EDIFICE" brand, and a limited edition model of the "MR-G" watch with the "Origin" form decorated with traditional metalworking techniques are not only garnering attention, but also hint at Casio's next challenge.

　In this article, I will focus on G-SHOCK and Oceanus from among these exciting new releases, and introduce five that I particularly wanted.

G-SHOCK “MR-G” Ref.MRG-BF1000RG-3AJR

　From G-SHOCK's top-of-the-line MR-G line, we have selected a new color of the MRG-BF1000, Ref. MRG-BF1000RG-3AJR, which is based on the Frogman diver's watch that boasts ISO 200m water resistance.

　The design motif of this watch is the Goliath frog, the world's largest frog. The dial features beige indexes and orange hands coated with luminous paint, creating a stoic look reminiscent of a tool watch. Furthermore, the combination with the khaki-colored rubber strap, reminiscent of the frog's body color, will tickle any man's adventurous spirit.

　The titanium case is made up of over 70 small parts. This structure allows for meticulous polishing down to the smallest detail while recreating the Frogman's iconic asymmetrical form. Furthermore, by meticulously incorporating cushioning material and O-rings to maintain airtightness between each part, the case combines beauty with excellent durability.

　The watch is packed with features, including a dive mode that records dive time and surface interval time, and a tide graph mode that simultaneously displays the tide and time. A sapphire crystal is pressed into the center of the case back, ensuring optimal reception of the built-in antenna. The sapphire crystal is coated with a green vapor deposition coating, allowing you to see the iconic Frogman frog character.

　This watch combines the appeal of a gadget with a design that complements urban style. Even if you don't enjoy diving, its military-inspired look makes it a great choice for adding a touch of style to your outfit.

Oceanus "OCW-S7000RA-5A"

　The Oceanus slim watch line, which promotes "Elegance, Technology," has launched a new series with a classical appearance, the "Retro Tone Collection." The Ref. OCW-S7000RA-5A belongs to this series and is a chronograph model limited to 1200 pieces worldwide.

　The dial of this watch has a three-eye vertical layout. The coloring combines silver vapor deposition, color painting, and a gradation pattern to create a deep brown hue. The surface is semi-matte finished using a newly developed mold, creating a calm atmosphere while allowing the light necessary for solar power generation to pass through to the module.

　Additionally, the sapphire crystal bezel, which is common to the OCW-S7000 series, has also been laser-processed to create a semi-matt finish. Furthermore, the center links of the bracelet have been given a hairline finish, which is different from the conventional style. The overall shine of the watch has been reduced, creating a unified, timeless look.

　The titanium carbide-treated case is slim and lightweight, measuring just 9.5mm thick and weighing just 83g. Equipped with multifunctional features such as radio wave reception and world time, it is expected to be useful in a variety of everyday situations. Its refined and understated appearance blends seamlessly with casual fashion and jacket styles, and will also create a stylish and individual look in business settings.

G-SHOCK “MT-G” Ref.MTG-B4000-1AJF

　From the "MT-G" series, which combines resin and metal, we have selected the Ref. MTG-B4000-1AJF, a groundbreaking G-SHOCK regular model that is the first to incorporate AI into its development process.

　During the development of this watch, AI performed load simulations based on the shock resistance data accumulated by G-SHOCK, calculating the optimal structure taking into account strength and workability. This was then repeatedly verified and improved by human designers. The resulting frame combines the strength of G-SHOCK with the unique aesthetic design that only AI can achieve.

　The frame is a fusion of carbon and stainless steel, and a new structure that integrates the band connection part reduces impact on the center case, achieving higher impact resistance. The unique carbon layered pattern visible from the side of the case, and the vertical and horizontal hairline finish on the two-piece stainless steel bezel further enhance the powerful impression.

　In terms of functionality, it includes "MULTIBAND6," Bluetooth mobile link functionality, Tough Solar, etc. This model incorporates cutting-edge AI technology, and is also attractive in that it allows you to experience Casio's new watchmaking.

G-SHOCK “MT-G” Ref.MTG-B2000YBD-2AJF

　Also from MT-G's "MTG-B2000" series is the Ref. MTG-B2000YBD-2AJF. This latest color model in the classic series incorporates MT-G's unique advanced technologies, such as the "Dual Core Guard Structure," which combines metal and resin to provide strong protection for the module, and the "Layer Composite Band," which combines a comfortable fit with the texture of metal.

　The case is primarily black, and the 12-sided bezel, common to the series, is finished in blue-gray IP. The combination with the pushers and crown, both finished in the same color, creates a cool two-tone look.

　The bezel frame is made of a laminated material of carbon fiber and blue glass fiber sheet, and the black and blue stripes on the side add a design accent. In addition, carbon sheet is wrapped around key areas of the case, not only showing a subtle grid pattern but also increasing durability.

　In terms of functionality, the watch connects to a dedicated app via Bluetooth and can acquire time information. It also features MULTIBAND6 and Tough Solar technology. With its versatile coloring, multifunctionality, and a price range of under ¥20, it's a perfect introduction to the luxury G-SHOCK line, along with the MTG-B4000 mentioned above.

G-SHOCK “FINE METALLIC SERIES” Ref.GM-2100YMG-9AJF

　Many attractive new models have appeared not only in the high-end G-SHOCK line but also in the sub-10 yen range. One that stands out among them is the new concept series "FINE METALLIC SERIES." This G-SHOCK features a fully metallic exterior that incorporates a newly developed "tough silicone band."

　The Ref. GM-2100YMG-9AJF is based on the popular slim "2100" series, combining a gold-colored metal case with a tough silicone band with a matching vapor deposition finish. This band features a gold vapor deposition treatment on skeleton resin, with silicone resin attached to it, giving it a shine similar to the texture of metal and a comfortable feel against the skin. The band also has the practical benefit of being easy to care for without worrying about scratches, making it an ideal choice for those with metal allergies.

　The dial is black with vertical graining, creating a striking contrast with the gold-colored indexes and hands. It is powered by a primary battery (no solar power) and has simple functionality, but its price of less than 50,000 yen is a big attraction. It also boasts the excellent shock resistance and 20-atmosphere water resistance you expect from G-SHOCK, making it a must-have gold-colored watch for casual wear.
