I had a SonyEricsson P800 (the first of that series) and it had the same wheel, but IIRC was plastic made (just like the rest of the phone). Oh man I was barely 20yo back then and I feel bad for the hype I had while waiting the phone to actually come out and buy it. I also remember I paid an insane amount of money for it, which then became standard a few years later thanks to Apple.
