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.
