Casio F-91WB-7A

Experience a modern, eco-conscious evolution of a global icon with the Casio F-91WB-7A. While the F-91 has been a "favorite for decades," this new version strips away the busy retro graphics of the original in favor of a minimalist, clean face with fewer mode indicators.

Dressed in a crisp all-white aesthetic, the F-91WB-7A is designed for the modern minimalist. It balances Casio’s legendary "slim and lightweight" heritage with a move toward sustainability, featuring a bio-based resin band that helps reduce environmental impact without sacrificing that classic "barely-there" comfort.

Key Features

• Minimalist Face Design: Features a simplified dial layout that removes the traditional colorful text for a sleek, monochromatic look that fits a "minimal design" lifestyle.
• Bio-Based Resin Band: Crafted from renewable organic materials, this strap is an environmentally responsible choice "expected to help reduce environmental impact".
• 7-Year Battery Life: Engineered with legendary efficiency, providing nearly a decade of reliable service on a single CR2016 battery.

• Essential Digital Toolkit: Despite the minimalist look, it is "always at the ready" with a 1/100-second stopwatch, daily alarm, and hourly time signal.
• Green LED Light: Equipped with a built-in LED, making the time and date "easy to see in darkness".
