Our take on the CASIO F-B100W-1A – Bluetooth & Step Counter

The Casio F-B100W-1A is the classic square F-91W shape rebuilt with Bluetooth and a step counter. It pairs with the Casio Watches app to set the time, manage alarms and review step history, and the step progress bar sits on the upper LCD. It keeps the F-series basics: five alarms, stopwatch, countdown timer, world time, an LED light and water resistance. It suits people who want a light, cheap-feeling digital with smart extras and no charging cable, but it is not a fitness tracker: no heart rate, no GPS, no sleep tracking, and the resin strap and acrylic crystal wear like the original.

About the CASIO F-B100W-1A – Bluetooth & Step Counter

The Casio F-B100W-1A is a digital watch from the Casio Standard collection. It keeps the square shape of the F-91W and has a matte black resin case, a black segmented resin strap and a light grey dial. Markings are impressed along the sides of the bezel.

The dial has two stacked LCD displays. The narrower upper display shows the day of the week, the date, a Bluetooth battery indicator and the Step Tracker progress bar. The main display shows the time in large digits, with seconds in the lower right corner. A front LED light illuminates the dial in low light.

Bluetooth Low Energy connects the watch to the Casio Watches app on iOS and Android. The connection sets the time automatically and manages alarms. It also lets you review step history. The watch has five alarms, a stopwatch, a countdown timer, world time, a MUTE function for alarms and a power saving mode. Four pushers on the case sides control ADJUST, MODE, LIGHT and SEARCH.

Questions and answers

Is the Casio F-B100W worth it over a standard F-91W?
If you want automatic time setting, alarm management from your phone and a step counter in the same square case, yes. If you only need a timekeeper, the plain F-91W does the same job with fewer parts to go wrong.
Does it count steps without a phone nearby?
Yes. The step tracker runs on the watch and shows a progress bar on the upper display. The phone app is for syncing time, alarms and reviewing step history, not for counting.
Do I have to charge it?
No. It runs on a coin cell battery like other Casio digitals, and the dial shows a Bluetooth battery indicator. There is no charging cable.
Is it waterproof?
It carries the WATER RESIST marking for everyday splashes and hand washing. Do not press the buttons underwater or take it diving.
Can I set alarms on the watch itself?
Yes, up to five alarms can be set with the pushers. Bluetooth just lets you manage them faster from the app.
What is in the box?
The watch on its resin strap and the usual Casio paperwork. No charging cable is included because none is needed.
Where is the CASIO F-B100W-1A – Bluetooth & Step Counter cheapest?
