For nearly four decades, the Casio F-91W has been an undisputed icon of the watch world. Beloved for its simplicity, durability, and unbeatable price, it defined the era of digital watches. Now, Casio is giving this cult classic a massive 21st-century upgrade.
Enter the Casio F-B100W—a watch that looks like it stepped straight out of the 1980s but hides surprisingly modern technology under its lightweight resin case. If you love the retro aesthetic of vintage Casio watches but want the convenience of modern fitness tracking and smartphone connectivity, the F-B100W might just be your perfect everyday watch.
Here is everything you need to know about how the new Casio F-B100W brings smart technology to a classic design.
Smart Features in a Vintage Shell
At first glance, the F-B100W is nearly identical in appearance to its legendary predecessor. However, looking at the top of the digital display reveals its biggest upgrade: a built-in accelerometer dedicated to fitness tracking.
1. Built-in Step Tracking
You no longer need a bulky smartwatch to keep an eye on your daily activity. The F-B100W automatically counts your steps, displaying your daily tally directly on the LCD screen.
- Set Daily Goals: You can set custom step goals ranging from 1,000 to 50,000 steps.
- Activity Graphs: The watch displays an hourly step count graph to help you visualize your progress.
- Inactivity Alerts: To keep you moving, the watch will remind you with a display alert and a beep if your step count is too low.
2. Seamless Bluetooth Connectivity
The “B” in the F-B100W stands for Bluetooth. By syncing the watch with the Casio Watches smartphone app, users unlock a suite of modern features:
- Auto Time Adjustment: The app automatically updates the watch’s time, ensuring perfect accuracy wherever you travel.
- Life Log Data: Your step counts and fitness data are beamed directly to your phone, allowing you to track your health history over time.
- Phone Finder: Misplaced your phone? Use your retro Casio to make it ring.
- Easy Configuration: Set your 5 daily alarms, countdown timers, and access world time for over 300 cities directly from your smartphone screen.
Iconic Design and Eco-Friendly Build
Casio knew better than to mess with a winning formula. The F-B100W retains the angular, simple case design that suits almost any wrist and occasion.
- Featherweight Comfort: Weighing in at just 26 grams and measuring a slim 8.8mm in thickness, you will barely notice you are wearing it.
- Eco-Conscious Materials: The watch band is made from bio-based resin, providing flexibility while being kinder to the environment. The strap also features a vented design to ensure breathability and comfort during daily use or workouts.
- Classic Functions: It still packs all the standard features you expect: a 1/100-second stopwatch (with a 200-lap memory), an LED backlight, and water resistance for everyday use.

Colorways to Suit Your Style
Casio is offering the F-B100W in three distinct variations:
- F-B100W-1A: The classic black case featuring nostalgic blue, red, and yellow detailing on the face.
- F-B100W-1B: A sleek, stealthy “all-black” version with a negative LCD screen and gray text (currently slated for the Japanese market).
- F-B100W-3A: A discreet sage green case accented with subtle turquoise touches.
Unbeatable Battery Life
One of the biggest frustrations with modern smartwatches is the need to charge them every single night. The Casio F-B100W eliminates this problem.
Despite constantly running a step tracker and maintaining a Bluetooth connection, the watch runs on a standard CR2016 coin-cell battery. Casio estimates this conventional battery will provide approximately 2 years of battery life before needing a replacement. It is the ultimate “set it and forget it” fitness wearable.
The Verdict
The Casio F-B100W successfully bridges the gap between the past and the present. It proves that you do not need a glowing OLED touchscreen to have a “smart” watch. By adding a step tracker and Bluetooth syncing to the beloved F-91W silhouette, Casio has created a highly functional, effortlessly cool, and incredibly practical daily wearer.
Whether you are a collector of retro gadgets or just someone looking for a simple, reliable watch that helps you stay active, the Casio F-B100W is a masterclass in modernizing a classic.
