By Silke Koltrowitz and Eric Auchard ZURICH/FRANKFURT (Reuters) – Apple Incs iPod upended the music industry, and its iPhone knocked Nokia off its smartphone perch, but Swiss watch makers breezily dismissed warnings that the technology giants new wristwatch gadget could do something similar to them. They are essentially transient products rather than items of enduring value, one Swiss watch industry expert sniffed. Franz Tuerler, owner of a luxury watch store on Zurichs main shopping boulevard, Bahnhofstrasse, said the appeal of Apple watches would be to a different class of customer who prizes technology over prestige and emotional attachment. I think the Apple Watch will be successful.
