As I've been doing lots of researching of all matters relating to wrist mounted time pieces, I also came across the amazing story of the G Shock watch.
The G-Shock was the brainchild of Casio engineer Kikuo Ibe. He was walking down the street when he bumped into another pedestrian, and his watch popped off of his wrist and smashed on the pavement. The watch had been a gift from his father and he was pretty upset about it. He then had the idea to create a watch which would have "triple 10" resistance, meaning it would have 10 year battery life, 10 bar water resistance and be able to survive a fall of 10 metres.
Kikue's team tested nearly 200 prototypes but were still not able to achieve their goal. Watching some kids bouncing a rubber ball at a playground gave him the inspiration that he needed to perfect his watch and in April 1983, the first G-Shock, the DW-5000C, was launched.
It started out as a slow seller so it was advertised in the US by showing an ice hockey player using the watch as a hockey puck and then showing that the watch was still working. They gained extra publicity when they were accused of false advertising. This of course worked in Casio's favour when they were able to prove that the watch really was as tough as claimed.
G Shocks now come in a huge range of different models, from fairly cheap digitals to expensive analogue chronograghs with an amazing amount of tech. To date more than a hundred million have been sold.
The story made me wonder how Kikue pitched the idea of his virtually indestructible watch to his bosses. How did he convince them that there was a market for it? Did he have to keep convincing them that he was onto something when his prototypes kept failing his tests?
I had a basic G Shock watch many years ago and had it for a very long time. Eventually the case cracked but after I replaced it with a Seiko Titanium watch, I still used it as a bedside alarm. So now a G Shock Mudmaster is on my shopping list as well.
