The GA-2100, which inherits the design concept of the first G-SHOCK, now features a smartphone link and Tough Solar while maintaining its octagonal form. To accommodate the increased number of components due to the added functionality, a new thin module with optimized board layout was developed. By combining this with the Carbon Core Guard structure, the watch maintains the same size as the previous model. This item is a collection piece, only tried on after being purchased new. Please purchase only if you understand that it is a pre-owned item. - Brand: G-SHOCK - Model: G-SHOCK GA-2100 - Color: Black/Yellow - Material: Carbon Core Guard - Functions: Digital display, Light, Stopwatch - Water Resistance: 200m water resistance Thank you for viewing.
