Casio W-735H-1AVDF Digital Sports Watch

The Casio W-735H-1AVDF is a digital sports watch built with a resin case and band. It measures 51.40 mm in thickness and offers water resistance to 100 metres. Quartz movement powers the digital display and integrated LED backlight with afterglow.

Suits daily wear and aquatic activity

This watch suits users who need a durable timepiece for swimming, snorkelling or everyday use. The dual-time function helps track a second zone. Buyers who want a metal bracelet, solar charging or smartphone connectivity should look at something else.

Steady readability and timing over long sessions

The resin glass and LED backlight maintain clear visibility during extended outdoor periods. Stopwatch and auto-calendar functions operate continuously without drift. The 100-metre rating holds under sustained water pressure rather than brief splashes.

Questions about this item

What size wrist will the 51.40 mm case fit?

The resin band adjusts via the buckle clasp to suit most adult wrists; the 51.40 mm case sits flat without overhang.

Will the digital display stay readable next to an older analog watch in low light?

The LED backlight with afterglow lights the digits on demand, so both time zones stay clear beside a non-illuminated analog face.

How do I confirm the 100 m water rating is intact after battery changes?

Press each button to verify the stopwatch, dual-time and calendar functions respond, then check the case back seal is seated before water exposure.
