Solar-powered outdoor watch

The Casio Pro Trek PRW6900YL-5 combines analog and digital displays in a 49.6 × 44.8 × 14.7 mm resin case with a brown leather strap. Solar charging keeps the rechargeable battery topped up without cable charging. Multiband 6 atomic timekeeping corrects the time automatically via radio signals. Built-in altimeter, barometer, compass and thermometer give hikers and field workers environmental data at a glance.

Thermals and power in daily wear

Tough Solar power draws energy from any light source so normal indoor and outdoor exposure maintains charge without user intervention. A power-saving function blanks the display when the watch is left in darkness to extend running time. Low-temperature resistance to -10 °C / 14 °F ensures the movement and LCD remain responsive in cold conditions. No active cooling or audible components are present so operation is silent.

Build quality and everyday connections

The resin case with black steel bezel and screw-down crown delivers 100 m water resistance for swimming and surface water sports. Smart Access electronic crown with quick-lock allows rapid setting changes while guarding against accidental adjustment. Fixed bezel and buckle clasp keep the strap secure during vigorous activity. Neo-Brite luminous hands and markers plus full auto double LED backlight with afterglow provide legibility in darkness without external tools.

Questions about this item

How do I set the time using the electronic crown and what step is often missed?

Pull the crown out, rotate to adjust the hands or digital display, then push it back in until the Quick-lock clicks; the step often missed is confirming the lock engages so the crown cannot turn accidentally.

What maintenance will the solar rechargeable battery need over time?

The solar rechargeable battery charges from light; keep the dial exposed to bright light regularly and replace the battery only when it no longer holds a full charge after extended exposure.

At what depth does the 100M water resistance limit appear during sustained diving?

The 100M rating covers swimming and snorkelling; sustained scuba diving beyond recreational depths exceeds the tested limit and should be avoided.
