Casio is stripping Pro Trek down to three hands, and that is the point. The company has opened Japan preorders for the PRJ-01, the first fully analog watch series in the Pro Trek lineup, with three variants priced from ¥25,300 (~$156), according to Notebookcheck.
The launch turns earlier leaked images from June into an official product line. It also marks a sharp break from the Pro Trek formula that has long leaned on digital displays, sensors and connected features.
The PRJ-01 series is Casio’s first fully analog Pro Trek family, trading the line’s usual feature-heavy face for a cleaner three-hand layout.
Japan Preorders Put the PRJ-01’s Analog Pivot on the Record
Casio has listed three PRJ-01 models on its Japanese store: PRJ-01-1JF, PRJ-01AE-7JR and PRJ-01AE-8JR. The base model starts at ¥25,300 (~$156), while the two AE versions rise to ¥31,350 (~$193) because they include the carabiner-style strap package.
The thesis is simple: Casio is testing how far Pro Trek can move away from its familiar digital identity without abandoning its outdoor purpose. The supporting evidence is in the dial. The PRJ-01 uses wide hour and minute hands, a slim seconds hand and a conventional analog layout instead of a crowded sensor-forward display.
The counterpoint is obvious. A stripped-back Pro Trek risks losing what made the range distinct for buyers who expect more instrumentation on the wrist. But the series still keeps Tough Solar, a calendar function, low battery alert and 100-meter water resistance, which means Casio has removed the visible complexity, not every practical feature.
| Model | Color / accent | Strap setup | Japan price | Main distinction |
|---|---|---|---|---|
| PRJ-01-1JF | Black with yellow accents | Standard rubber strap | ¥25,300 (~$156) | Entry model |
| PRJ-01AE-7JR | White/light grey with orange accents | Fabric strap with carabiner attachment | ¥31,350 (~$193) | Clip-to-gear option |
| PRJ-01AE-8JR | Dark grey with teal accents | Fabric strap with carabiner attachment | ¥31,350 (~$193) | Clip-to-gear option |
Tough Solar Keeps the Minimal Dial From Becoming a Fashion-Only Pro Trek
Tough Solar is doing important work here. Without it, the PRJ-01 could look like a style exercise wearing a Pro Trek badge; with it, the watch keeps a core Casio outdoor trait while moving to a cleaner face.
All three models use resin cases and offer 100 m water resistance. Additional source material says the case measures 39.1 mm wide and 11.6 mm thick, with a total weight of 32 grams. It also says Casio uses bio-based resin for the case, case back and standard strap.
The design choices point toward everyday utility rather than spec-sheet overload. The strap uses a tuck-under design meant to keep the tail from catching on sleeves or equipment, and the PRJ-01 uses a rotating guard bezel instead of a standard screw-down crown. In its default position, that bezel covers the crown; turning it 45 degrees exposes the crown for time and date setting.
The strongest objection is that none of this replaces the missing Pro Trek sensors. That is true. But it also clarifies the product: the PRJ-01 is not trying to be the most capable Pro Trek on paper. It is trying to be the most visually conventional one while retaining enough outdoor hardware to justify the name.
The ¥31,350 AE Variants Make the Strap the Real Upgrade
The PRJ-01AE-7JR and PRJ-01AE-8JR cost ¥31,350 (~$193), a premium over the ¥25,300 (~$156) base model. The reason is the strap system: the AE variants include a fabric strap with a carabiner attachment, letting wearers clip the watch to a backpack, belt loop or outdoor gear when it is not on the wrist.
That makes the upgrade practical, not cosmetic. The source material says the strap system is designed for quick swaps between rubber and fabric, and the carabiner attachment can replace the standard urethane band without specialized tools. For hikers, campers and gear-focused buyers, the value is not just another strap; it is another carry mode.
The counterpoint is price discipline. Buyers are paying roughly ¥6,050 more for the AE package, and the core watch functions remain the same across all three models. That premium only makes sense if the clip-on use case matters.
This is where the PRJ-01 feels different from Casio’s more familiar collector-driven releases. MLXIO has recently tracked Casio headlines from the leak side, including the Pokémon G-Shock leak putting Pikachu on a full-size GA-110 and the $5K G-Shock leak revealing Casio’s blue sapphire flex. The PRJ-01 news is different because it is now an official preorder listing with model names and Japan pricing attached.
The Missing Global Date Is the Constraint for Buyers Outside Japan
Casio has not announced global release details for the PRJ-01 series. The confirmed launch window is July 2026 in Japan, with preorders already live there.
That leaves several practical gaps. There is no confirmed US, Europe or wider international launch timing in the supplied material. There is also no regional pricing, retailer list or delivery schedule outside Japan.
The forward-looking read is cautious. If Casio follows with international listings, the PRJ-01 will become easier to judge as a broader Pro Trek direction rather than a Japan-first experiment. If no global rollout appears, the watch remains more limited in practical reach, and buyers outside Japan will be watching for local announcements or import availability.
Key Takeaways
- The PRJ-01 is the first fully analog Pro Trek series, signaling a major design shift for Casio’s outdoor lineup.
- Casio is targeting buyers who want a cleaner three-hand outdoor watch without dropping basics like Tough Solar and 100-meter water resistance.
- The AE models cost more because they add the carabiner-style strap package, giving shoppers a clear price-versus-accessory choice.
