Casio W-800H-1AVDF Digital Watch

The Casio W-800H-1AVDF is a men's digital watch built for everyday wear and active use. Its resin case and band keep the profile light while the 100m water resistance supports swimming and snorkelling. A quartz movement drives the auto calendar, dual time, stopwatch and multi-function alarm. The LED backlight ensures the display stays readable in low light.

Thermals Noise and Power

Quartz movement means no mechanical noise and virtually no heat during normal operation. The watch draws negligible power from its internal cell, so there is no daily charging routine to manage. Resin construction does not conduct temperature extremes against the wrist in hot or cold environments. Operation stays silent whether the stopwatch, alarm or backlight is active.

Build Quality and Connectors

The case, bezel and band are all resin with a buckle clasp for a secure, adjustable fit. Resin glass protects the digital display from everyday knocks and scratches. Fixed bezel and 44.20 mm case thickness give a compact square shape that slides under cuffs easily. No proprietary connectors or charging ports are present; the watch runs on a standard user-replaceable battery.

Questions about this item

How do I install the resin band and which buckle orientation do people get wrong?

Thread the resin band through the fixed resin case lugs, then fasten the buckle clasp so the prong faces the twelve o'clock side; reversing it makes the tail point the wrong way.

Which component will need replacement first during long-term ownership?

The quartz movement runs on a single button cell; expect to swap the battery every two to three years when the display dims or the LED backlight weakens.

What limit appears first when I use the stopwatch and backlight continuously?

The 1/100-second stopwatch can run for twenty-four hours, but the LED backlight draws enough current to shorten battery life if used heavily each day.
