Gaining its now legendary toughness from Ibe’s revolutionary decision to suspend the module inside a hollow rubber structure, the G-Shock has been the go-to name in superbly durable and precise wristwear ever since. 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.
