# Retro Smart Watches The Casio F-B100W Modernizes the Iconic Digital Watch with Bluetooth By Amy Duong | Published 2026-08-12 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/casio-fb100w References: [casio](https://www.casio.com/jp/watches/casio/product.F-B100W-1B/)  Casio has introduced the F-B100W, a modern interpretation of its iconic F-91W that preserves the [classic rectangular design](https://www.trendhunter.com/trends/casio-aq240e3a) 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](https://www.trendhunter.com/trends/gshock-glide-gbx100s) 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](https://www.trendhunter.com/trends/retrofuture-wrist-tech), the F-B100W focuses on practical everyday functionality without introducing health sensors such as heart rate or sleep tracking.
