Casio Classic 37 mm digital watch

The Casio W-800-1AVCF is a 37 mm resin-cased digital watch built for everyday wear. Quartz movement drives a grey digital display with LED backlight. Water resistance is rated to 100 m and the battery is specified to last 10 years.

Suits buyers wanting a single low-maintenance

This watch fits adults who need dual time zones, a 1/100-second stopwatch, multi-function alarm with snooze and a full auto-calendar running to 2099. It is not for buyers who require analog hands, smartwatch connectivity, solar charging or a metal bracelet.

Resin band and buckle complete the package

The 8-inch resin strap fastens with a buckle and can be resized for a secure fit. No extra software, charging cable or proprietary app is bundled; the watch delivers all stated functions from the moment it is worn.

Questions about this item

What strap size does the 37 mm case accept?

The resin band is adjustable and resizable to fit a range of wrist sizes.

Can the LED backlight be read while wearing diving equipment?

The LED backlight illuminates the digital display for low-light visibility, and the 100 m water resistance supports swimming and snorkelling.

How do I confirm the 10-year battery is still active after setting the watch?

The auto-calendar runs until 2099 and the display shows time, date and dual time zones; if all functions operate the battery is working.
