My understanding:
WR = Weather resistant. Pentax description mentions splash resistance but nothing about dust. A matter of damning with faint praise, methinks.
* = "sealed". Whatever that implies. Pentax mentions dust resistance and uses stronger language when describing * glass.
AW = All weather? Perhaps a somewhat different approach owing to the engineering necessary to make a lens of the size and nature of the 560.
None will automatically get replaced in the event of water or dust damage. I don't know which criteria Pentax uses for this part of the warranty.
