A long-rumored update to one of Casio’s foundational digital watch lines has appeared in a new retailer listing, firming up details that earlier leaks could only approximate. The device, identified as the F-B100W series, brings connected functionality to the design DNA of the original F-100, which debuted in 1978 as Casio’s first fully plastic-cased watch and helped pave the way for the classic F-91W.
Confirmed Connectivity and Step Tracking
The “B” in the model name indeed signifies Bluetooth, enabling synchronization with a companion smartphone application referred to in the listing as “Mobile Link.” A built-in motion sensor handles automatic step counting, with users able to set a daily target anywhere between 1,000 and 50,000 steps. Activity data can be transferred to the app and stored as a running log. The strap material is listed as bio-based resin.
Physical Dimensions and Core Functions
The case measures 41.9 mm by 38.1 mm, with a slim 8.8 mm profile, and the total weight lands at just 26 grams. Power is supplied by a CR2016 coin cell rated for approximately two years of life, rather than the Tough Solar charging found in higher-priced G-Shock lines. Beyond the fitness basics, the module retains a full suite of timekeeping tools: a 1/100-second stopwatch with memory for 200 records, a countdown timer, five daily alarms, dual-time display, an hourly chime, and a fully automatic calendar programmed through the year 2099.
Color Options and Availability
The retailer listing showcases three colorways. A black-on-black variant carries the code F-B100W-1B, a black case with blue accents is shown as F-B100W-1A, and a green resin version appears as F-B100W-3A. Pricing has not yet been disclosed, and Casio has not officially announced the model. However, packaging artwork shown in the retailer material points toward an August release window, aligning with recent sightings of new Edifice and Pro Trek models.
