Casio breathes fresh life into the iconic F-91W with the new F-B100W model, combining classic style with modern features like a built-in step tracker. This nod to nostalgia appears unchanged on the outside, maintaining the beloved rectangular design that first gained popularity in the 1980s. The initiative is part of how the company brings back 1980s trends, ensuring that the watch fits seamlessly into today’s smart watch landscape. Priced at around ¥8,800 (approximately $55), this updated version has already sold out in Japan, at least for now, underscoring its eager reception.

Echoing the 1980s revival seen in other products, 7-Eleven’s 2017 Nissan GT-R Collectible blends nostalgia with clever design, worth exploring for enthusiasts.

Reviving 1980s Appeal with Modern Features

True to its roots, the F-B100W closely mirrors the original in size and weight—measuring 41.9 × 38.1 × 8.8 mm and weighing 26 grams. Alongside retaining classic features like an amber LED backlight and water resistance, this edition introduces a bio-based plastic strap enhanced for comfort with ventilation slits. The watch uses a traditional battery, promising nearly two years of uninterrupted service. The brand rejuvenates 1980s elegance while adding conveniences that cater to today’s needs.

The standout transformation of the F-B100W includes Bluetooth connectivity, enabling automatic time synchronization and alarm toggles. This function finds utility alongside another innovative inclusion—the phone finder feature, adding convenience without complexity. Users can now sync their step count and lap split times to their phones via a companion app. The watch supports goal-setting and records up to 200 laps, while also reminding users to move with an optional inactivity alert. As they revive 1980s charm, these enhancements blend time-tested design with present-day functionality.

While it doesn’t feature more advanced smartwatch capabilities like heart monitoring or sleep tracking, this Casio model focuses on essential updates in a timeless design. Available in three color variants—each with its unique aesthetic—the F-B100W offers choices of stylish accents: black with retro blue, red, and yellow details, and another in all black with a negative display. By merging the old with the new, the brand effectively revives 1980s style without sacrificing modern needs.
