The Casio G-Shock GA-2100LXB-1A9ER stands out for its ruggedness and sporty design. Built for adventurers and style enthusiasts alike, it features a black resin case with an imposing diameter of 50 mm. This synthetic material - lightweight and resilient - gives the watch uncompromising durability while keeping the total weight down to just 51 g, ensuring all-day comfort. The octagonal shape and clean lines of the case give it a distinctly contemporary look that fits any situation. Four pushers on the sides let you navigate effortlessly through the watch's many functions.
The dial of this Casio G-Shock commands attention with its textured finish, topped by a mineral crystal that adds exceptional depth and visual dimension. Its hybrid analog-digital display allows intuitive reading of hours, minutes, and seconds, as well as additional information such as day, month, and date. The hands feature a luminescent coating for optimal visibility in the dark, further enhanced by a Full Auto LED function that illuminates the dial.

1/100-Second Stopwatch: Measures elapsed time with 1/100-second precision. Measurement range is 00'00''00 to 59'59''99 for the first 60 minutes, then 1:00'00 to 23:59'59 beyond that. Resolution is 1/100 second during the first hour, then 1 second thereafter. Measurement modes include elapsed time, split time, and 1st/2nd place times.

At the heart of this watch beats a Japanese quartz movement from Casio. Renowned for its accuracy and reliability, this type of mechanism delivers consistent timekeeping with minimal drift, regardless of use. The movement offers multiple functions including a chronograph precise to 1/100th of a second, a countdown timer, and alarms settable up to 24 hours.
Designed to combine style and comfort, the band of this G-Shock is crafted from black resin, a material valued for its flexibility and resistance to the elements. The band color pairs seamlessly with the case, creating a clean, unified look. Thanks to its pin buckle closure, this band delivers enhanced security and easy adjustability.
The Casio GA-2100LXB-1A9ER watch features an impressive water resistance of 20 ATM, guaranteed by a screw-back case, allowing not only submersion to depths of 200 meters but also enhanced water resistance during activities such as diving, swimming, and yachting.
