Sports Digital Watch with 100m Water Resistance

The Casio WS-1400H-8AV is a quartz-powered sports watch built for daily wear and water-based activities. Its resin case and strap resist moisture and impact while keeping weight low. A square digital display shows the time, month, day and date at a glance. Dual-time functionality lets travellers track a second zone without a smartphone.

Replaces basic analogue

The jump is worth it when you need reliable 100m water resistance for swimming or snorkelling without moving to a dive computer. Buyers who want more storage for logs, builders who need a second card for redundancy, or anyone requiring smartwatch notifications will not find those features here. The fixed bezel and quartz movement prioritise simplicity over programmable timers or solar charging.

Simple strap adjustment with buckle clasp

The resin band threads through a traditional buckle so sizing takes seconds and needs no tools. What usually goes wrong is cutting the strap too short before confirming the fit over a wetsuit cuff or bulky sleeve. The resin crystal resists scratches better than acrylic but can still scuff if dragged across rough surfaces.

Questions about this item

What wrist circumference does the 44.50 mm resin case and buckle clasp accommodate?

The resin strap with buckle clasp adjusts to fit most adult wrists; the 44.50 mm case sits flush on medium to large wrists.

How do I set the dual time and date on the digital display, and which button sequence is often missed?

Hold the adjust button until the seconds flash, use mode to cycle through hour, minute, month, day and second time zone, then press adjust again to save.

When should the quartz movement battery be replaced, and does the 100m water resistance need re-testing?

Battery life is typically two to three years; have a watchmaker replace the cell and pressure-test the 100m seal at the same time.
