Casio Collection Watch AQ-S820W-3BVEF

Introducing the Casio AQ-S820W-3BVEF, a perfect fusion of solar technology and military aesthetics distinguished by its integral matte olive green finish. The resin case presents a deep green tone that extends uniformly throughout the entire structure, while the outer bezel incorporates functional MODE, ADJUST, LIGHT and SEARCH markings in clear typography. The black dial elegantly contrasts with white triangular indices and silver luminescent hands, while the rectangular digital display integrates discreetly at the 6 o'clock position.

At its heart beats the Casio 5745 module, an analog-digital caliber powered by Tough Solar technology that eliminates the need for battery replacement. The digital display shows stopwatch information, countdown timer, 5 independent alarms and world time with multiple time zones. Functions are controlled via side pushers marked on the bezel, offering direct access to 1/100 second stopwatch, two countdown timers of up to 99 minutes 55 seconds each, full automatic calendar and LED light for nighttime display reading.

This piece belongs to the Casio Timeless Collection, a line representing the constant evolution of Japanese watchmaking since 1974. Casio has revolutionized the sector with innovations like Tough Solar technology, which converts any light source into energy, guaranteeing continuous operation without maintenance. The philosophy of creating watches that combine precision, durability and advanced functionality is perfectly reflected in this model that fuses the best of both worlds: intuitive analog reading and digital versatility.
