I bought a Casio G Shock in 1984, when I was a Royal Navy Clearance Diver. I still have the same watch and apart from a battery change, 4 or 5 times, and a new strap it is still going strong. I have been tempted to but more expensive watches since, but my rationale is, why? When my 17 yr old son wanted a watch I suggested a Casio, he saw this on the internet and I bought it for him. Nearly 30 yrs later the G Shock is still, pound for pound, the best buy on the market. I hope his new G Shock gives him the same service as mine has, it will be money well spent.
