Casio has introduced the F-B100W, a modern interpretation of its iconic F-91W that preserves the classic rectangular design while adding a selection of smart features. Measuring 41.9 × 38.1 × 8.8 mm and weighing just 26 grams, the watch retains familiar essentials including five daily alarms, water resistance, an amber LED backlight, hourly chimes, and a replaceable battery rated for up to two years. A redesigned bio-based resin strap with additional ventilation improves comfort, while Bluetooth connectivity enables automatic time synchronization, dual-time settings, alarm management, and a built-in phone finder through the companion app.
The most significant addition is a built-in step counter that syncs activity data to a smartphone, allowing users to track daily goals, monitor progress, and record up to 200 lap times. An optional inactivity reminder also encourages movement through audible and on-screen alerts. Rather than competing with feature-packed smartwatches, the F-B100W focuses on practical everyday functionality without introducing health sensors such as heart rate or sleep tracking.
