The Family: Master of G

Casio’s Master of G family has always been about showcasing the very latest technology Casio has to offer long before it is introduced to the main G-Shock and Pro Trek lines. No matter what the conditions or the terrain; the wearer can rely on the Master of G series’ innovative features to deliver impressive toughness and unbeatable reliability, all while still retaining sporty and exclusive styling. Designed to be “watches for tough professionals,” Casio’s Master of G range elevates the already revolutionary G-Shock to the pinaccle of durable watchmaking.


The Brand: Casio

Casio was established in 1946 by Japanese engineer Tadao Kashio. The company entered the timepiece market in 1974 with the release of the Casiotron, the world’s first Auto Calendar watch. Only eleven years after entering this field, Casio completely reshaped global thought about the function a watch should perform with the release of the pioneering and now legendary G-Shock family. Innovation and world firsts have defined the company’s history ever since, the most striking of these being the release of the first ever touch screen watch in 1991, 24 years before the Apple Watch, and the first ever wrist camera watch in 2000. In short, Casio was producing smartwatches decades before the term had even been coined. Add to this the hipster popularity of the company’s retro designs, and Casio has firmly cemented its reputation as a famously reliable and precise name in both analogue and digital watches.
