On Tuesday, June 9, Casio’s unannounced G-Shock MRG-B5000SA-2 surfaced in a leak as a blue-accented square MR-G model expected to cost above $5,000. The timing matters because the watch is being framed as the second piece in Casio’s reported MR-G 30th anniversary run, according to Notebookcheck.
The image was published by Casioblog, the Russian enthusiast site cited in the report. Casio has not announced the model, so the name, materials, finish, pricing and launch window remain leak-based until the company confirms them, as with the separate Pokémon G-Shock leak.
June 9 leak puts the MRG-B5000SA-2 second in Casio’s MR-G anniversary queue
The reported MRG-B5000SA-2 appears to be a premium take on Casio’s square G-Shock format, dressed with blue accents and the kind of metal construction associated with the top-end MR-G line. Notebookcheck says Casio appears to be preparing at least three new MR-G models for the sub-line’s 30th anniversary.
The leak positions the MRG-B5000SA-2 after the MRG-BF1000EB, described in the source as a high-end Frogman anniversary model seen earlier this year. A third anniversary watch, reportedly based on the MRG-B2000 series, is also said to be in development.
That sequence is important. If accurate, Casio is not treating the MR-G anniversary as a single commemorative release. It is building across multiple MR-G forms: a Frogman, a square 5000-series-style model, and potentially an MRG-B2000-based watch.
| Reported anniversary model | Status in source material | Key detail |
|---|---|---|
| MRG-BF1000EB | Seen earlier this year | High-end Frogman variant |
| MRG-B5000SA-2 | Newly leaked | Blue-accented square MR-G |
| MRG-B2000-based model | Reportedly in development | Third anniversary model |
The practical caveat is clear: this is still a leak. The available reporting does not include a Casio press release, final product page, production count or confirmed regional rollout.
Blue inserts and a possible AIP finish are the leak’s luxury signals
The most visible change in the leaked render is a pair of blue inserts placed at the top and bottom of the case, between the bezel segments. Casioblog speculates that those pieces could be either sapphire crystal elements or titanium designer accents.
The model suffix may be a clue. Notebookcheck notes that the “SA” in MRG-B5000SA-2 could refer to whichever material or treatment Casio is using, though that remains unconfirmed.
Blue circular accents around the buttons extend the color theme. The case itself also appears to carry a deep blue-grey tone, with the source suggesting it could be Arc Ion Plating, or AIP.
AIP is a hardening surface treatment described in the source as similar to DLC coating. Notebookcheck says it is used in aerospace applications and associated with traditional Japanese metalworking. If confirmed here, it would make the finish part of the story, not just the color.
The base platform is already material-heavy. The MRG-B5000 platform uses a Ti64 titanium case, a DAT55G titanium band rated at three times the hardness of pure titanium, and a Cobarion cobalt-chrome bezel alloy rated at four times harder than pure titanium.
That matters because the square G-Shock shape is familiar, but the MR-G execution is not casual resin-watch territory. The analysis from the leak is straightforward: Casio appears to be using a heritage silhouette as the frame for exotic metals, segmented construction and premium finishing.
For readers tracking Casio’s non-MR-G design experiments, MLXIO has separately covered Carbon Dial Steals Casio Edifice's Mechanical Spotlight and Two Textured Dials Make Casio Edifice Look Pricier. Those are different product lines, but they show why materials and surface treatment details tend to drive the conversation around Casio’s higher-interest releases.
Above-$5,000 expectation keeps this square G-Shock in MR-G collector territory
The leak points to pricing north of $5,000 for the MRG-B5000SA-2. That would keep the watch firmly in premium MR-G territory rather than the broader G-Shock mass market.
The expected feature set is familiar for MR-G: Tough Solar, Multi-Band 6, Bluetooth, 200-metre water resistance and sapphire crystal. The source does not provide deeper software or connectivity details, so Bluetooth should be read only as part of the expected spec list for now.
The price logic, if the leak holds, rests less on new everyday functions and more on construction. The reported case metals, possible sapphire or titanium blue inserts, potential AIP coating and anniversary positioning are the parts that would separate this model from a standard square G-Shock.
Still, several buying-critical facts are missing. The leak does not confirm whether the watch will be limited, how many units Casio might produce, or whether allocation will vary by region.
Casio’s next announcement has to settle materials, coating and timing
Notebookcheck says an announcement is expected within the next two months. Until then, the biggest open questions are the ones collectors will care about most: whether the blue inserts are sapphire or titanium, whether AIP coating is real, and whether the final watch matches the leaked render.
Regional information is also absent. Japan, U.S. and European pricing have not been confirmed, and the source does not state availability, allocation or dealer timing.
Final images will matter more than usual here. A blue-grey coating, reflective inserts and segmented metal bezel construction can look very different in studio renders, leaked images and daylight wrist shots.
The next signal is Casio’s own confirmation. If the company validates the MRG-B5000SA-2 name, the anniversary positioning and the above-$5,000 bracket, the remaining test will be whether the finished materials justify another ultra-premium square G-Shock built around a familiar shape.
Key Takeaways
- The leak suggests Casio may be planning a broader MR-G 30th anniversary lineup rather than a single commemorative watch.
- The MRG-B5000SA-2 could bring premium materials and blue sapphire-style accents to Casio’s iconic square G-Shock format.
- Pricing above $5,000 would position the model firmly in Casio’s high-end collector segment.
