Casio G-Shock Classic

Description

The Casio G-Shock GA-2100BM-7A5ER is a sporty yet fashionable wristwatch from the popular Classic GA-2100 series. It combines the iconic octagonal bezel design with a translucent resin case and a transparent strap that allows a glimpse of the watch's inner workings. The metallic silver-toned dial gives the watch a trend-conscious flair, making it the perfect accessory for a street-style look. Thanks to the Carbon Core Guard structure, the watch is shock-resistant and water-resistant to 20 bar, making it ideally suited for everyday wear and sporting activities.

The analog-digital dial displays hours, minutes and the day of the week via analog hands, while the digital display provides seconds, date, month and additional information. The Super Illuminator dual-LED backlight ensures excellent readability even in the dark. Features such as world time across 31 time zones, a 1/100-second stopwatch, a countdown timer and five daily alarms make the GA-2100BM-7A5ER a versatile companion.
