For those of you who wonder how we journalists manage to live on our not very ample salaries, you will be glad to know that we often moonlight as part-time teachers. In my case, I teach English to super-rich Saudi students at a local college in Jeddah.I say super-rich as I just noticed that two students taking their weekly quiz with me this week were both wearing Chanel’s J20 white enamel watch with diamonds. Just like the one seen here at the right.Here’s Chanel own hyperbolic description of its first foray into the world of sports watches: “A stream of diamonds on high tech ceramic! The perfect appeal and brightness of white diamonds, the elegance and refinement of black diamonds. The contrast of over 110 brilliants (1 carat) subtly enhances the unique sheen of the case and the strap made of high tech ceramic: An avant-garde material, scratchproof, intensely and deeply black.”What the heck are black diamonds?! Well my students had the white version. And guess how much it costs? A cool $7,000 according to one American website selling them. So you see, when I say mega-rich, I mean it!I was thinking of buying myself one, but even with my teaching income, I know for sure I could never afford one.
