The GA-2100SKE-7AER – Jellyfish name comes from the famous Crystal Jellyfish (Aequorea victoria) that shares the same characteristics as this custom watch. It is transparent and is filled with a beautiful array of colors. The Crystal Jellyfish CasiOak is as playful as it gets, with hand-painted dial, index, and letters on the bezel, all done by the talented The Dial Artist.

Transparent watches have always captured our imagination, and when the GA-2100SKE-7AER got introduced earlier this year, we knew we had to create something totally unique and spectacular. The decision was easy to make considering we had an overwhelming request to make something fun and exclusive with the new Jellyfish watch.

The Casio G-Shock GA-2100SKE-7AER which is known as the ”CasiOak Jellyfish” among watch collectors has been a huge hit since its launch in 2021. The nickname ‘Jellyfish’ is commonly used in the watch world and refers to its transparent and skeletonized look. Its official name from Casio is represented in its reference number ‘SKE’ that stands for ‘Skeleton’.

The Jellyfish is the latest drop from Casio which is intended to widen their range of CasiOak selection. The watch is waterproof, however we would recommend against recurring use in sea, ocean and swimming pools, due to the nature of the Transparent Resin.

It measures 45mm in diameter but wears comfortably on smaller sized wrists. The watch features a mineral crystal and is shock resistant and water resistant to 200m.
