I have a black G7700; great features, perfect size; it's a great watch...except for the silver metal bezel on the front. I want it black. Permanently. I've tried roughing the surface then spray painting it with outdoor paint, brushing it with automobile paint, but it chips and rubs off after a couple of weeks. (BTW, the watch looks phenomenal all black.) I even called Casio to see if they sold the black bezels that I've seen on 7700's in different colors, but no. Is there any way to dye or otherwise color a silver metal bezel that won't have to be touched up?
