I tried getting an answer directly from Citizen to no avail, so I thought I'd try and see if anyone here could help. I am interested in getting the AR1113-04a model which is said to have a gold "tone." I've read up on the differences between tone, plating, and PVD and heard the anecdotes about how some brands have the coating wear off within only a couple months. Does anyone have any insight on the quality if Citizen's plating/tone? Anyone know how many microns are on this model or how many are typically used for "gold tone"? How long should I expect this to last if I wear it a couple times a week with a long sleeve shirt? Thanks everyone.
