## Description

The all-new GA-2100 series from G-Shock arrives this year. Like the new GA-2000, the GA-2100 is a Carbon Core Guard model, but unlike other recent carbon models, it has a shock look thanks to its octagonal bezel and its traditional shaped resin bands. The GA-2100 is really inspired by the design and shape of the very first G-Shock DW-5000C, but in a combination of analog and digital forms. At 11.8 millimeters, it's the thinnest G-Shock analog-digital watch on the market.

Review: I love this watch not too bulk, light, a little classy too everyday watch for sure.
Review: Tras un año de uso, es el reloj que más ocupó y es muy cómodo, el diseño me parece perfecto, casual y deportivo, clásico y futurista.
