Among Casio watches announced by October 4, 2025, three stand out for different reasons: the G-SHOCK MTG-B4000 for its hybrid frame and connected timekeeping, the EDIFICE EFK-100 for its mechanical movement, and the limited MRG-B5000HT for its hand-hammered finish. These are editorial picks based on documented features and design—not results of comparative wear or performance testing.
How these 2025 Casio picks differ
Casio’s 2025 announcement roster spans G-SHOCK, MR-G and EDIFICE, rather than one kind of watch. The company’s dated product index includes releases such as the Fine Metallic and Bright Metallic series, a Barbie collaboration, FROGMAN MR-G and GA-V01, alongside the three picks below. The index records announcements; it does not rank models. This roundup is limited to announcements dated on or before October 4, 2025, and does not include later entries in the archive. Casio’s 2025 model index provides the dated roster.
| Model | Best-supported appeal | Documented distinction |
|---|---|---|
| G-SHOCK MTG-B4000 | Features and construction | Layered carbon-and-glass-fiber frame, six global time-calibration stations and Bluetooth Mobile Link |
| EDIFICE EFK-100 | Mechanical movement | Mechanical movement with an approximately 40-hour power reserve when fully wound |
| G-SHOCK MRG-B5000HT | Craft and limited production | 500 pieces worldwide announced; individually hand-hammered bezel and bracelet components |
Price, current stock, dimensions, weight, water resistance, warranty and independent performance comparisons are not established by the cited launch announcements. Check the exact regional model and current retailer listing before buying.
G-SHOCK MTG-B4000: the feature-led pick
Announced May 27, 2025, the MTG-B4000 is the most technology-focused choice here. Its frame combines laminated carbon and glass-fiber sheets, creating a visible layered pattern at the side. Casio says generative AI contributed to structural exploration: simulations and proposed structures were assessed against strength, material properties and machinability, then refined by human designers. That is a description of Casio’s design process, not a claim that AI independently designed or tested the finished watch.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
For timekeeping, Casio lists calibration signals from six global stations and Bluetooth Mobile Link through its app. That combination makes the MTG-B4000 the clearest pick for someone drawn to connected functions as well as a distinctive frame. The announcement does not establish real-world accuracy or comparative durability. Casio’s MTG-B4000 announcement describes the materials and functions.
EDIFICE EFK-100: the mechanical pick
Announced June 16, 2025, the EFK-100 is the straightforward choice for a reader seeking a mechanical Casio. Casio states that the movement has an approximately 40-hour power reserve when fully wound. The family pairs that movement with a motorsport-inspired design, but the dial material depends on the variant.

EFK-100CD-1A
This version uses forged carbon on the dial, according to Casio.
EFK-100D variants
The blue, green and white EFK-100D models use electroforming to reproduce a forged-carbon-like texture. They should not be described as having the same forged-carbon dial as the CD model. Casio’s EFK-100 announcement gives the family’s movement and variant details.

G-SHOCK MRG-B5000HT: the craft and scarcity pick
Casio announced the MRG-B5000HT on July 24, 2025, as a worldwide edition of 500 pieces. Its bezel and bracelet are individually hand-hammered by tsuiki artisan Kazuya Watanabe. Casio describes tsuiki as a forging technique in which metal plate is hammered into a three-dimensional form.
The components use DAT55G, a titanium alloy developed in Japan; Casio says it is three times harder than pure titanium. Those details support a craft-focused collector profile, not a value recommendation. The announced edition size does not establish present availability or resale value. Casio’s MRG-B5000HT announcement documents the edition and finishing.

Other notable Casio releases in 2025
Casio’s dated index also covers other 2025 launches, including G-SHOCK Fine Metallic, Bright Metallic, a Barbie collaboration, FROGMAN MRG-BF1000RG and GA-V01. Casio’s FY2026 first-half results briefing names the GA-V01 and PRO TREK PRJ-B001 among FY2025 Good Design Award recipients. It also describes the SAN-100H “Sadokei” as a sauna-use watch with a display designed to be easy to see and a one-push 12-minute timer. Those mentions establish recognition or intended use, but do not provide enough detail for a technical comparison with the three picks above. Casio’s FY2026 first-half results briefing contains those descriptions.
Which one should you choose?
- Choose the MTG-B4000 if the layered carbon-and-glass-fiber frame and connected time-calibration features are the main attractions.
- Choose the EFK-100 if a mechanical movement is the priority; compare the CD and D variants carefully if the dial material matters.
- Consider the MRG-B5000HT if hand-finished metalwork and a formally limited worldwide edition are what you value most. Its announcement alone cannot tell you whether it can still be bought.
These labels reflect the features Casio documented in its 2025 announcements, not independent testing. For a purchase decision, verify the exact suffix, market-specific specifications, price and stock with Casio or a retailer in your country.
