I've never understood or related to the fetish for expensive watches. UK reviewer Ken Kessler is a collector, occasionally dropping a watch reference into a review. There in no time, man, only the eternal present. Unless you have to be at a record store when it opens. ;-)
Now old guitars and drums, there's something worth spending big money on. Neil Young owns Hank Williams' Martin acoustic, Marty Stuart Clarence White's B-Bender Telecaster. I own one of Jim Gordon's (Derek & The Dominos, etc.) Camco drumsets. None of his cymbals, unfortunately. He played the best I've ever heard. The worst? Ginger Baker's. Real trash can lids.
