About CasiOak Watches

Shop CasiOak watches in Australia — the G-Shock GA-2100 and GA-B2100 series with the iconic octagonal bezel that earned the "CasiOak" nickname. Authorised Casio dealer, free shipping Australia-wide.

What Is a CasiOak?

The "CasiOak" is the nickname given to Casio's G-Shock GA-2100 series, coined by watch enthusiasts for its octagonal bezel that draws comparisons to certain Swiss luxury sports watches — at a fraction of the price. The GA-2100 launched in 2019 and quickly became one of G-Shock's most popular models globally. It features a slim Carbon Core Guard case, analogue-digital display, 200m water resistance, and G-Shock's signature shock resistance. Watch Direct is an authorised Casio dealer in Australia stocking current CasiOak models.

CasiOak Models at Watch Direct

GA-2100 Series: The original CasiOak. Slim Carbon Core Guard resin case, analogue-digital display, 200m water resistance. Available in a wide range of colourways.

GA-B2100 Series: The Bluetooth-connected CasiOak. Adds G-Shock Move app connectivity for time sync and step tracking while keeping the same iconic octagonal case profile.

Why Choose a CasiOak?

The CasiOak delivers G-Shock durability — 200m water resistance, 10-year battery, shock and magnetic resistance — in a slimmer, more refined profile than traditional G-Shock models. The octagonal case design works equally well with casual and smart-casual outfits. At $149–$299, it's one of the best-value tool watches available.
