The face is a nice bright white, but the crystal (XTL? Oh great... a new set of vocabulary to pick up! :) ) has yellowed. I'll likely get a glass replacement one day, but for now I figured I'd at least try to get a quick fix to get this one away from the watch in case it is celluloid going bad. Thanks for the suggestion of surface yellowing: I hadn't considered that. I'll try polishing it and see what happens.
I've found a few places that will do proper glass replacements, but so far none in Canada and I'm a bit leery of Int'l shipping at the moment considering I need this for a wedding in the fall.
