Classic Casio watches remain a symbol of durability and style, but now they integrate the digital connectivity demanded by today’s life. Want to know which are the five best to buy this year? We explain it below.

Casio icons that never go out of style

Casio F91W: the accessible and lightweight king

The Casio F91W is a classic that has won over millions of people since 1989. Its thin rubber strap and lightweight design make it ideal for active users, like surfers who wear it under their wetsuits.

Despite its simplicity, it offers all the basic stopwatch and alarm functions, and is available in various colors, even with metallic bezels for an elegant touch.

Improvement in the Illuminator F105W-1A version

A limitation of the F91W is the lack of sufficient illumination, which the Illuminator model solves while maintaining the same aesthetic. This makes it more practical without losing the vintage essence.

Smartwatch and durability: when the classic becomes technological

GMW-B5000-D1: metal and Bluetooth connectivity

If you seek durability with technology, the GMW-B5000-D1 is a complete smartwatch with a metal case, solar power, and atomic time control via radio frequency. The Bluetooth connection allows easy adjustment from your phone.

Its robust and elegant design is perfect both for adventures and daily use, representing the balance between tradition and innovation.

DW5600: the legendary G-Shock of the Triple 10

The DW5600, designed by Kikuo Ibe, is famous for meeting the "Triple 10" rule: 10 years of battery life, water resistance up to 10 bars, and drop protection from 10 meters.

It is an indestructible watch, with editions that include solar technology, and a model that many consider the best for a lifetime.

Special and nostalgic designs that triumph today

CA53W: the calculator watch of pop culture

The CA53W model is not only a gadget for quick calculations but also a highly valued retro symbol. It appeared in iconic movies and series like "Back to the Future" and "Breaking Bad."

It also features an alarm, dual time zone, stopwatch, and a precise calendar up to 2099, all in a surprisingly slim profile.

AQ240E: vintage style with a modern touch

The AQ240E stands out for its turquoise color and very thin integrated bracelet. Without an analog second hand to avoid overcrowding the dial, it is a digital watch that fits current fashion trends and offers timeless elegance.
