Our take on the G-Shock GA-2100 "CasiOak" Full Metal Gold
The GA-2100 became a phenomenon because it delivered an octagonal, integrated-look sports watch for around $100. The full-metal GM-B2100 in gold takes the same silhouette into stainless steel with a solar-powered movement and Bluetooth timekeeping, which is where the design always deserved to be.

Where and how to buy
Casio sells directly and through major retailers, so retail availability is good outside of launch week. Gold-finished models can sell out quickly for gifting seasons — set a stock alert rather than paying a resale markup.
Prices and availability change constantly. See our authentication checklist before any pre-owned purchase, and our servicing cost guide to budget for ownership.
