Casio upgrades the classic F-91W watch with smart functions, and it’s already sold out in Japan

Without a doubt, the Casio F-91W is a legendary timepiece that is still available to buy for $20. While the digital watch has retained its nostalgic charm all these years, it is indeed a little left behind when it comes to smart functionality. Casio is set to change that now with the F-B100W timepiece, which adapts the modern functions expected in a smart timekeeper. The classic 1980s digital watch in the rectangular silhouette, upgraded with the goodness of step counting – I’ll take that any day!

On the outside, this Casio timepiece looks like the trusted F-91W, but inside it has more to offer, making it a sweet deal. For now, the watch is available in Japan for ¥8,800 (around $55), and it’s not surprising it has already been sold out, at least for now. That’s almost double the price tag of the original, which is still up for $22, but you’ll also have to factor in the generational leap in smart features this new model touts.

Most of the F-B100W’s functions are fairly straightforward, and the specifications are also very close to the original, measuring 41.9 × 38.1 × 8.8 mm and weighing 26 grams. The timepiece retains features including an amber LED backlight with adjustable glow, water resistance, an hourly time signal, and five daily alarm options. For improved comfort during long hours, the bio-based plastic strap now has improved ventilation slits. Major changes come in the form of a watch battery (as opposed to a rechargeable cell), which lasts for almost two years.

What’s making this Casio timepiece a big buzz already is the inclusion of Bluetooth, which automatically syncs time or toggles the alarms or dual time display. In the mix is the phone finder feature, which can be a really useful addition without all the unwanted nuances. What I’m most excited about is the addition of the step counter and lap split time function, which can be directly synced to your phone with the companion app. You can set goals, record up to 200 laps, and monitor the progress on the watch screen as well. For times when you get too engrossed in work, the F-B100W also sends an inactivity alert via a beep and on-screen prompt. Of course, that is an optional feature that can be turned off as well.

It doesn’t have any other smartwatch features like a heart rate monitor, sleep diagnosis, or even BP monitoring, but that’s the point. The retro-modern Casio watch has all the timekeeping functions, and the most essential smart features without making the wearer too finicky about the vitals. F-B100W comes in three color variants: 1AJF, 1BJF, and 3AJF, which have a black case with a positive LCD and retro blue, red, and yellow dial accents, and all black with a negative display and gray text, respectively.
