Casio’s F-B100W Brings Retro Style, Bluetooth Sync, and Step Tracking This August

Casio F-B100W leak reveals a retro digital watch with Bluetooth, step tracking, and three color options

Casio appears to be preparing a new retro-inspired digital watch, and the latest retail leak gives the clearest look yet at what fans can expect. The unreleased Casio F-B100W has reportedly appeared in a third-party retailer listing, revealing key features such as Bluetooth connectivity, step tracking, a lightweight resin case, and three color variants.

The F-B100W looks set to blend the charm of Casio’s classic digital watches with a few modern health and connectivity features. While Casio has not officially announced the model yet, the newly surfaced listing lines up closely with earlier information surrounding the watch.

The “B” in F-B100W appears to stand for Bluetooth. According to the listing, the watch can connect to a companion mobile app for data syncing. This feature would allow users to keep a running log of activity data, making the watch more useful for everyday fitness tracking without turning it into a full smartwatch.

One of the biggest upgrades is the built-in step tracker. The Casio F-B100W is said to use a motion sensor to count steps automatically throughout the day. Users can reportedly set a daily step goal ranging from 1,000 to 50,000 steps, giving the watch a simple but practical fitness-focused edge.

The design is expected to appeal strongly to fans of vintage Casio watches. The F-B100W is linked to the spirit of the classic F-100, a model first introduced in 1978 and remembered as one of Casio’s early full-plastic case digital watches. That design language later helped shape some of the brand’s most recognizable affordable digital models.

Despite the added Bluetooth and step-tracking functions, the F-B100W does not appear to rely on solar charging. Instead, it is listed with a CR2016 coin cell battery rated for around two years of use. That keeps the watch simple, lightweight, and likely more affordable than higher-end connected Casio models.

The leaked specifications list the case size at 41.9 x 38.1 x 8.8 mm, with a weight of just 26 grams. That makes it slim and easy to wear daily, especially for users who prefer a no-fuss digital watch over a bulky smartwatch.

The strap is also said to use bio-based resin, which could make the F-B100W a more environmentally conscious option within Casio’s affordable digital lineup. It is a small detail, but one that may matter to buyers looking for practical watches made with more sustainable materials.

In terms of everyday functions, the Casio F-B100W seems well equipped. The leaked listing mentions a 1/100-second stopwatch with 200-record memory, a countdown timer, five daily alarms, dual time, an hourly time signal, and a fully automatic calendar programmed through the year 2099.

Three versions of the watch have reportedly appeared so far. The F-B100W-1B is expected to feature a black-on-black design, while the F-B100W-1A appears to combine a black case with blue accents. A third model, the F-B100W-3A, is listed in green resin.

Pricing has not been revealed, and Casio has not yet confirmed the launch officially. However, the packaging information shown in the retailer listing suggests a possible August release window. If accurate, the F-B100W could arrive as one of Casio’s most interesting retro digital watch updates of the year.

With Bluetooth syncing, step counting, a lightweight body, classic styling, and a traditional coin cell battery, the Casio F-B100W could become an appealing choice for buyers who want basic fitness tracking without the complexity of a smartwatch. For fans of affordable Casio digital watches, this leaked model is definitely one to watch.
