Casio F‑B100W – Classic Digital Style with Modern Smart Features

The Casio F‑B100W brings together the iconic digital watch design of the 1980s with practical modern features for everyday convenience. The classic angular case and large LCD display preserve the timeless look, while Bluetooth® connectivity and a built‑in step tracker add smart functionality to support your daily lifestyle.

With Mobile Link, you can access useful functions on both your watch and smartphone. The built‑in accelerometer automatically counts your steps, and you can easily check your daily progress on the LCD screen. Pairing with your phone via Bluetooth® enables automatic time correction, simple configuration of watch settings, and seamless transfer of step data to the CASIO WATCHES app. Use the life‑log data to manage your health and activity each day.

The slim 8.8 mm resin case and lightweight 26 g construction ensure comfortable wear. The bio‑based resin strap features slits on the inner side to improve airflow and reduce sweat, while the outer design follows the classic F‑91W style. Casual design and advanced technology come together to deliver smart, health‑conscious support with everyday comfort.
