Tag Heuer 2000 Aquagraph numbers and luminescence...

Question

I bought my aquagraph as a bonafide dedicated dive watch and have logged over 400 dives over the past 3 yrs. I noticed that several numbers and some of the bezels luminescence has come off earlier this yr. I found out from Tag that these items are painted on. Doesn't Tag know that water and paint do not mix and stick well and eventually these painted items will peel off. I have had the watch into the service center 3 times this yr. to have the numbers repainted. Well it has been less than 6 months and the numbers are coming off again. One would think that anodizing the numbers would remedy this shortcoming. I thought this watch would hold up for many yrs. I was wrong. Any suggestions.
