Too tacky, too pretentious !
I would get one if I could afford it. I've seen the 24k gold ProVari's in person and they are really nice looking, even with the finish wearing off. An almost indestructible gold finish? I could go for that.
Gold ProVari, watch, pen, tie clip, money clip = tasteful
Gold ropes, massive gold rings, gold front teeth = pretentious and tacky
