What the F-B100W does with a phone
The watch pairs over Bluetooth with Casio’s CASIO WATCHES app. Casio lists automatic time correction, app-based watch configuration and transfer of step data among the connected features. The Japanese app feature list also names a phone-finder function, world time, time-and-place logging and daily life-log functions.
#1 Best Overall
- Micro Light, Hourly Time Signal, Auto Calendar
- 12/24 Hour Formats
- Dial Code: Digital
- Water Resistant
- Daily Alarm
Phone pairing is useful for syncing and configuring the watch, but the listed features do not make it a full-featured smartwatch. Casio’s product material supports basic step tracking and connected watch functions; the reviewed specifications do not establish heart-rate monitoring or GPS.
Step tracking: what it measures
Casio says the F-B100W uses a built-in accelerometer to detect movement and automatically count steps, including during activities such as walking and jogging. The watch displays a daily step count and a progress graph toward a goal. Casio’s specifications describe the function, but the cited product information does not provide independent tracker-accuracy testing.

Traditional watch functions and hardware
Beyond steps and phone features, the F-B100W has a 1/100-second stopwatch with memory for up to 200 lap times, a countdown timer, dual time, five alarms and an LED backlight. Its case measures 41.9 × 38.1 × 8.8 mm, and Casio lists a weight of 26 g. It has a resin case and a band that includes bio-based resin components.
| Specification | Casio-listed detail |
|---|---|
| Case dimensions | 41.9 × 38.1 × 8.8 mm |
| Weight | 26 g |
| Battery | CR2016; approximate battery life of two years |
| Water resistance | Listed as “Water Resistant”; the consulted US specification does not state a depth rating |
Because Casio’s consulted US listing gives no numeric water-resistance rating, it does not establish suitability for swimming. Check the specification for the exact regional variant before relying on it in water.

Retro styling, not simply an F-91W successor
Casio describes the F-B100W’s angular digital-watch look as carrying forward a design style dating to the 1980s. Its international product page also notes that the outside of the strap follows the F-91W band design. The F-91W is therefore a useful styling reference, but the available product information does not establish that the F-B100W is simply its successor.
That combination is the point of the model: familiar digital-watch styling and everyday timekeeping, with a limited layer of phone connectivity and step counting rather than a broad smartwatch feature set.
