AR coated sapphire crystals... any downsides?

Hi everyone,

Just wondering if there are any downsides to AR coated sapphire crystals. I don't think it is darker or anything, but I just want to make sure...

(sometimes I like to see the light reflected off my watch's crystal and directed to wear I point my watch) :-d

A double sided AR looks great but the smudge factor is definitely there. My PO and Sinn U1 are impossible to keep clean, and short of carrying around a little bottle of lens cleaner and a cloth, nothing you wipe it with will get it clean. I prefer inner side AR only, and if it has a dome, it has to have AR. Once you seen a good AR'd crystal, you won't want anything else.
