Casio is adding three new analog watches to its outdoor-focused Pro Trek brand. The PRJ-01 series, launching in the Japanese market this July, steps away from the bulky, sensor-heavy digital designs usually associated with the lineup. Instead, these new models offer a straightforward three-hand analog layout housed in a much smaller footprint.

Design Details

The two higher-tier models, the PRJ-01AE-8JR and PRJ-01AE-7JR, ship with a carabiner attachment that can replace the standard urethane band. The swap doesn’t require specialized tools, allowing users to detach the watch case from their wrist and clip it directly to a backpack strap, belt loop, or outdoor gear.

In terms of size, the PRJ-01 is relatively small for an outdoor watch. The case measures 39.1mm wide and 11.6mm thick, bringing the total weight to just 32 grams. Casio is using bio-based resin for the case, case back, and the standard strap.

The strap itself uses a tuck-under design, which routes the tail end of the band against the wrist rather than leaving it exposed. This is a practical design choice intended to keep the watch from catching on jacket sleeves or equipment.

Casio has also changed how the crown operates. Rather than a standard screw-down mechanism, the PRJ-01 uses a rotating guard bezel. In its default position, the bezel covers the crown entirely to prevent accidental time adjustments or snagging. Turning the bezel 45 degrees exposes the crown at the bottom right of the case, allowing access to the time and date settings.

The dial is fully phosphorescent, meaning the entire white background glows in low-light environments to provide contrast against the hands and markers. The dial is also light-transmissive, which allows the built-in solar charging system to draw power from sunlight and indoor lighting.

Casio claims the watch can operate for approximately five months on a full charge, even without further exposure to light. It also features 100 meters of water resistance and a mineral glass crystal.

Pricing and Availability

The carabiner-equipped PRJ-01AE-8JR (grey) and PRJ-01AE-7JR (white) are priced at ¥31,350 ($192), while the base PRJ-01-1JF (black) model is priced at ¥25,300 ($156). All three models are currently available for pre-order in Japan.

Casio has added a new line of automatic watches to its Edifice brand in Japan. The EFK-200 series consists of five models that incorporate materials like forged carbon and electroformed dials.

Design Details

The most expensive model in the new range is the EFK-200XPB-1AJF. Priced at ¥74,800 ($460), it features a case and dial made entirely of forged carbon. Forged carbon is a composite material created by mixing carbon fiber with resin and pressing it under high temperatures. This manufacturing process results in a random, marbled pattern on the watch’s surface and keeps the overall weight down to 81 grams. This specific model comes with a black ion-plated stainless steel bezel, a urethane band, and a push-button butterfly clasp.

Casio is also offering a mixed-material version, the EFK-200CD-1AJF. Priced at ¥55,000 ($338), this model retains the forged carbon dial but swaps the carbon case for a standard stainless steel one, paired with a solid stainless steel band. The change in materials increases the total weight to 153 grams.

The remaining three models in the lineup replace the carbon fiber with electroformed dials. Casio says that these dials are treated with a multi-layer lacquer to create a textured, gradient finish. The EFK-200D-2AJF and EFK-200D-4AJF feature standard stainless steel cases and bands and are priced at ¥55,000 ($338). The EFK-200DG-5AJF includes a gold ion-plated case and band, bringing its price to ¥66,000 ($406).

Internally, all five watches are identical. They are powered by a Japanese-made automatic movement visible through a screw-lock exhibition case back. The 21-jewel movement operates at 21,600 vibrations per hour and provides a standard 42-hour power reserve. It includes a hacking seconds function and a date display, with Casio stating a mean daily accuracy of -20 to +40 seconds.

The physical dimensions are a notable shift for the Edifice brand. The cases measure 38mm in diameter, 43.6mm lug-to-lug (43.8mm for the carbon case), and 11.9mm thick, making them highly wearable for a variety of wrist sizes. Standard durability features remain intact across the board, with every model in the EFK-200 series including a scratch-resistant sapphire crystal and 100 meters of water resistance.

Availability

The EFK-200 series is currently available for pre-order in Japan ahead of its official retail launch in July.

In related news, Casio has recently launched the W738H digital watch series in the US with vibration alerts, followed by three new retro-inspired A140WE digital watches.
