Outdoor running watch for students

The allentian 9811 is a lightweight digital watch built for daily outdoor running and student use. A 50.49mm dial and 24mm strap width give a clear, readable face on a 48 gram case that sits close to the wrist.

ABS case with PU strap and alloy back

The case uses ABS plastic with a pressure-resistant design rated for shock and drop resistance. A plexiglass mirror resists scratches, while the alloy bottom cover and PU plastic strap combine durability with a comfortable fit for extended wear.

WR50M water resistance and CR2025 power

Rated to 50 metres water resistance, the watch handles rain, sweat and brief immersion without issue. A single CR2025 button cell powers luminous display, alarm, hourly chime, running seconds and day or date readouts in 12 or 24 hour format.

Questions about this item

What waterproof rating does the 9811 watch carry and what does it allow?

It is rated WR50M, meaning it withstands splashes, rain and brief immersion such as swimming, but is not intended for diving or high-pressure water sports.

What are the case diameter and strap width so I can check fit?

The case measures 50.49mm across and the strap is 24mm wide, giving a large-screen profile that suits wrists comfortable with oversized dimensions.

How is the CR2025 battery installed and what mistake should I avoid?

Remove the alloy bottom cover, place the CR2025 cell positive side up, then reseat the cover evenly; the common error is inserting the battery upside down, which prevents the watch from starting.
