I am using casio g-shock watches from almost 5-6 years and its my second g-shock & I can say its really tough and durable as it can easily last around 5-10 years though mine got stolen , they are quite big and bulky but I adds extra toughness and mascular looks to it . it have various features like stop watch, auto illumination, world clock , calender & much more and its water resistance ( 20 bar) and front glass is also very tough and its not easy to scratch or break them . battery last for around 2-3 years which depends on your usage ( alarm, illumination do use more battery ) . I would recommend casio g-shock watches to any age group and its a great casual tough watch , which will last you a long time as g-shock quality is really high .
