In 1983 the first G-SHOCK was born. The brainchild of Casio engineer Kikuo Ibe, this new timepiece shattered the reputation of a watch as a fragile piece of jewellery and fused function with design to create the uniqueness that is G-SHOCK.
Heartbroken by a broken pocket watch given to him by his father, Mr. Ibe set about creating ‘the unbreakable watch based upon a triple 10 philosophy. It should be water resistant to 10bar, have a minimum 10 year battery life and most importantly, survive a minimum 10 metre drop. Consumed by this new dream, the young engineer subjected prototype after prototype to rigorous testing, revisiting and revising his designs and calculations, persisting and persevering until arriving at the famous design still produced today in the form of the G-SHOCK DW-5600.
