Casio Collection Watch F-91WB-2A1EF

Introducing the Casio F-91WB-2A1EF, the electric blue reinterpretation of the legendary F-91W that has conquered generations. This version maintains the iconic rectangular silhouette but dresses it in a vibrant matte blue that embraces both case and strap. The light grey LCD display contrasts elegantly with the intense blue, while the side pushers integrate seamlessly into the monochrome design. The ventilation slots on the strap not only provide comfort but add the technical touch characteristic of Casio aesthetics.

At its heart beats the Casio module 593, a digital caliber offering essential functions with absolute precision. The main display shows hours, minutes and seconds, with PM and alarm indicators clearly visible. Features include stopwatch with hundredths precision, daily alarm, auto calendar and backlight for night reading. The simplicity of its interface hides complete functionality that has made the F-91W the best-selling digital watch in history.

Part of the Casio Timeless Collection, this piece represents the timeless design philosophy that Casio perfected since the 80s. The original F-91W became a cultural phenomenon, appearing on wrists from students to presidents, proving that technical excellence needs no ornamentation. With over 40 years of constant evolution, Casio remains pioneer in accessible and reliable watch technology.
