     When I was seven, my father gave me a Timex, my first watch. I loved it, wore it for years, and

haven't had another one since it stopped ticking a decade ago. Why? Because I don't need one. I have a

mobile phone and I'm always near someone with an iPod or something like that. All these devices (装置)

tell the time-which is why, if you look around, you'll see lots of empty wrists; sales of watches to young

adults have been going down since 2007.  

     But while the wise have realized that they don't need them, others-apparently including some

distinguished men of our time-are spending total fortunes on them. Brands such as Rolex, Patek Philippe

and Breitling command shocking prices, up to £250 000 for a piece.  

     This is ridiculous. Expensive cars go faster than cheap cars. Expensive clothes hang better than

cheap clothes. But these days all watches tell the time as well as all other watches. Expensive watches

come with extra functions-but who needs them? How often do you dive to 300 metres into the sea or

need to find your direction in the area around the South Pole? So why pay that much of five years' school

fees for watches that allow you to do these things?

     If justice were done, the Swiss watch industry should have closed down when the Japanese discovered how to make accurate watches for a five pound note. Instead the Swiss reinvented the watch, with the aid of millions of pounds' worth of advertising, as a message about the man wearing it. Rolexes are for those

who spend their weekends climbing icy mountains; a Patek Philippe is for one from a rich or noble family;

a Breitling suggests you like to pilot planes across the world.  

     Watches are now classified as "investments" (投资). A 1994 Patek Philippe recently sold for nearly £350 000, while 1960s Rolexes have gone from £15 000 to £30 000 plus in a year. But a watch is

not an investment. It's a toy for self satisfaction, a matter of fashion. Prices may keep going up-they've

been rising for 15 years. But when fashion moves on, the owner of that £350 000 beauty will suddenly

find his pride and joy is no more a good investment than my childhood Timex.
