Casio has officially confirmed that the new G-Shock GA-2100K series is on the way to the UK, bringing a nightclub-and-festival-inspired twist to one of the brand’s most popular “CasiOak” silhouettes. After launching in Japan at the start of January 2026, three models are now listed for the UK market: the GA-2100K-1A, GA-2100K-2A, and GA-2100K-5A.
UK pricing is set at £109 per watch through Casio’s online store. While Casio hasn’t pinned down an exact on-sale date yet, the product listings suggest availability is expected sometime in January 2026. Shoppers who don’t want to miss the drop can use the “sign up now” option on the product page to get an email alert when the watches officially go live.
What makes the GA-2100K lineup stand out is its event-ready styling. Casio leans into the atmosphere of nightclubs and music festivals with a smoke-like finish across the translucent resin case and strap, giving the watches a hazy, light-diffusing look. Neon accents add to the theme, echoing the laser lighting commonly seen at live shows and late-night venues. Each colorway has its own personality: the GA-2100K-1A pairs a grey base with turquoise highlights, the GA-2100K-2A mixes blue with punchy orange accents, and the GA-2100K-5A blends a brown-orange tone with red detailing.
Beyond the design, these models keep the practical features that make the GA-2100 range such a go-to for everyday wear. You get world time support, a stopwatch, a countdown timer, and multiple alarms, making it a strong option for travel, training, or busy schedules. The hybrid analog-digital layout is supported by a double LED backlight, helping illuminate both the hands and the digital display when lighting conditions are poor. There’s also a day-of-the-week indicator, and—true to G-Shock expectations—200-meter water resistance for confidence in wet conditions.
For buyers outside the UK and Japan, the global rollout is still unclear. Casio hasn’t confirmed when (or if) the GA-2100K models will land in other regions such as the US, the Netherlands, or Germany, but the UK listings are a strong sign that wider availability could follow.
