The Casio F-91W is an undisputed legend of digital watchmaking. For decades, it has stood as the standard for functional, affordable timekeeping. Now, Casio has introduced a successor that brings this iconic silhouette into the modern era.

The new F-B100W maintains the familiar rectangular design that made the original a global staple. However, it incorporates a range of connected features designed for today's user. The watch now includes Bluetooth connectivity, which allows for automatic time syncing, alarm management, and dual-time displays. It also features a phone finder tool, ensuring that you are never left searching for your device.

Fitness tracking is the most significant addition to this classic chassis. The watch now supports step counting and a lap split timer, with all data syncing directly to a companion app. Despite these technical additions, the design remains grounded. The device keeps the traditional battery, which offers a two-year lifespan, avoiding the frequent charging requirements of most modern smartwatches. The strap has also been updated with ventilation slits to provide better comfort during daily wear.

The F-B100W has debuted in Japan at a price point of ¥8,800. Demand has proven high, with the initial run selling out shortly after launch. It arrives in three color variants, keeping the retro aesthetic of the original while providing the utility required in a contemporary timepiece. This release strikes a balance between nostalgia and necessary utility, appealing to long-time fans of the brand who want updated functions without the complexity of a full-featured smartwatch.
