With a sleek resin strap and mineral glass crystal, it combines practical functions like world time, multiple alarms, and a stopwatch with a stylish design that fits seamlessly into both professional and active lifestyles.

## Description

Three new color variations of the Tough Solar GAS-100 add new flavor to this case design. Variations on a basic black design are created by three different bezels. The GAS- 100 comes with a stainless steel bezel for a standard design that goes well with a wide range of fashion styles. The GAS-100B has a black aluminum bezel for a cool design. A CASIO original molding process is used to produce deposition coated hour markers that combine with the metal bezels to create a look of elegance.

Review: Excelente reloj. - Llego en tiempo. Y bien. Solo si viene en la caja cartón, de presentación. No caja de lámina. Fuera de eso. Reloj nuevo. Y con instructivos en español. Y garantías. El reloj es una lindura!! Buen movimiento de la manecillas al activar la función necesaria en los diales redondos, al fondo y así no estorben las manecillas. Gran reloj. Solar!!!! :) (
