Casio PRO TREK Solar Watch - Black / Yellow | PRJ-01-1DR combines straightforward three-hand analog timekeeping with outdoor-focused durability and comfort. Its compact black case, yellow-accented hands and indexes, and soft bio-based resin band create a practical design suited to hiking, trekking, travel, and everyday wear.

The watch measures 44.4 × 39.1 × 11.6 mm and weighs only 32 g, making it one of the more compact and lightweight PRO TREK options. The case, case back, and band use bio-based resin, while the band end tucks underneath for a neat fit and reduced interference with sleeves.

A distinctive rotary guard bezel can be turned by 45 degrees to expose the crown for time and date adjustments, while its standard position helps protect against accidental operation. The full phosphorescent dial absorbs light and glows across its entire surface for improved nighttime visibility, while still allowing light through for solar charging.

The PRJ-01-1DR is solar powered and can operate for approximately five months from a full charge until the hands stop. It also features a low-battery alert, Mineral Glass, date display, Neobrite details, and 100-meter water resistance, making it a practical outdoor watch with minimal maintenance.
