Built for outdoor use

The Casio Pro Trek PRJ-B001-7 is a sports watch designed for men who spend time outside. Its resin case and strap use bio-based materials. A grey dial sits behind mineral crystal. Tough Solar charging keeps the quartz movement running without battery changes.

Suits daily wear and recreation

This model fits wrists that want a single watch for work, travel and weekend activity. The analog-digital display shows the time and date at a glance. Smartphone Link synchronises the clock automatically. Buyers who need a dedicated dive computer or advanced navigation sensors should look elsewhere.

Solar power and 100 m water resistance

Light charges the cell continuously, giving long running time between exposures. The case is rated to 100 metres, so swimming and snorkelling are comfortable. The 46.00 mm thickness and fixed bezel limit how flat the watch sits under tight cuffs.

Questions about this item

Does the PRJ-B001-7 need a smartphone to set the time and use Smartphone Link?

The watch syncs time automatically via the CASIO WATCHES app over Bluetooth Low Energy, so a compatible phone is required for initial pairing and ongoing link functions.

Will the 46.00 mm resin case fit under the cuff of a typical outdoor jacket?

At 46.00 mm thick the case sits proud of the wrist, so a tight sleeve may catch; most outdoor jackets with adjustable cuffs clear it without issue.

How can I confirm the Tough Solar cell is charging after I put the watch in sunlight?

The digital display shows a charging indicator icon when the solar panel receives enough light, and the battery level graphic rises as it stores power.
