I've just lashed out a whole fiver for a Casio F91W. I'll wear it for sport, it has stopwatch, timer, alarm, all sorts. For a fiver. It's advertised as genuine, we'll see when it lands. Apparently there are a number of fakes, even at such a low price. It hardly seems worth bothering. Nevertheless, I think it's still the best selling watch worldwide. I'm looking forward to it landing, it's cost less than a pint of lager.
