Casio Releases Final Model in G-SHOCK Celestial Guardian Series

May 4, 2018

4 May 2018 – First unveiled in January 2018, the G-SHOCK Celestial Guardian series features reinterpretations of the Four Symbols by acclaimed artist and graphic designer JAHAN LOH, with a specific colourway for each of the four respective watches to match different wardrobes and styles. The final watch in the series, the GA-800CG-1A, features the Black Turtle.

In traditional Chinese culture, the Four Symbols are celestial beasts that each correspond to a specific season, cardinal point, and quadrant of the sky. The Azure Dragon, Vermillion Bird, White Tiger, and Black Turtle didn’t just represent a system of organising and understanding the world, but were also guardians that kept the world in order.

With help from JAHAN LOH, CASIO has put a twist on these beasts by transposing them to the wrist. To modernise these traditional motifs and keep their influence subtle, JAHAN created a backdrop of clouds that are reminiscent of camouflage patterns all over each watch, before hiding the celestial guardians in plain sight. In this watch, a silhouette of the Black Turtle in its typical representation – a turtle entwined with a snake – is repeated several times on the strap. Only someone who is looking for it will recognise it though, making it a secret among those who are in the know.

The GA-800CG-1A will be released at the end of May at G-FACTORY outlets island-wide (except IMM); it’s pricing will be announced closer to launch.


A contemporary artist, JAHAN LOH’s works have straddled both fine art and commercial projects. He first shot to fame with his drawings for Taiwanese hip-hop group Machi’s album art and music videos, which won him several awards including MTV’s CD Cover Design of the Year. Since then, he has collaborated with a range of artists, such as John Matos and Jakuan Melendez, while also presenting solo exhibitions. JAHAN LOH has demonstrated an interest in various mediums, from painted pop art to brass sculptures, and is currently based in Singapore.
