Casio Runner Digital Watch for Runners

The Casio STR300-7 is a digital sports watch built for runners and fitness enthusiasts who need precise lap tracking. It offers a 1/100th second stopwatch with 60-lap memory to store split times for later review. A pacer signal and distance calculation help maintain target speeds during training. The 10-year battery life removes the hassle of frequent changes.

Resin Case and Band Fit Small Wrists

The oval 35 mm resin case and matching resin band fasten with a buckle for a secure fit during movement. At 6.5 inches the band suits smaller adult wrists without excess strap. Water resistance to 50 metres protects against splashes, sweat and brief immersion. The lightweight resin construction keeps the watch comfortable over long sessions.

Multi-Function Timing Handles Extended Sessions

Five daily alarms, dual time display and a countdown timer support varied training schedules and everyday timekeeping. The stopwatch and lap memory operate reliably across repeated intervals without reset lag. Battery endurance is rated for ten years of continuous digital-quartz operation. Grey digital dial shows day, date, month and year at a glance.
