Casio G-Shock GA-2100-1A2ER

Overview

Casio combines analog and digital clarity in a robust resin package with a black case and black/blue dial. Under the mineral glass, the 5730 module provides a quick overview with date, day, 24-hour display and stopwatch. 20 ATM and a black bezel make the model ready for water and everyday life, while the blue strap provides a sporty contrast. The result is a durable, easy-care watch that works just as well at the gym as it does on the commute.

Comfort

Despite a present diameter of 46 mm, the case sits low with a height of 12 mm, so the watch slides under the cuff without getting in the way. The flexible 26 mm resin strap follows the wrist and adjusts quickly with a buckle for a secure fit. The lightweight, durable construction reduces fatigue during long use, and smooth edges and clear buttons make handling smooth in everyday life, even with gloves or cold fingers.

Summary

This model distills Casio's practical DNA: quartz precision, combined ana-digi layout and high durability. 20 ATM, mineral glass and resin protect in all weathers, while calendar functions and a stopwatch simplify planning and training. The discreet color scheme with a black case and blue strap is easy to match. A reliable everyday watch that can withstand the pace, keeps the style and requires minimal maintenance for many years.
