The six-figure brief involves raising G-Shock's profile through fashion, music, and extreme sport initiatives. The agency will also promote the brand at UK music festivals and in Ibiza.
In addition, Frank PR will manage G-Shock's press office and will target the fashion and lifestyle press in particular.
Since Casio launched G-Shock in 1983 over 60 million of the watches have been sold in nearly 100 countries.
Radiator PR was the incumbent agency.
