Pentax has two different WR designations:

a) WR, and

b) DA*.

WR lenses have limits as to what to expect from them. WR lenses cannot be used for a prolonged time in adverse weather. Instead of them, use DA* lenses, which were purpose-built for such use. DA* lenses have better seals overall.

In short:

  • Light rain (WR) — Prolonged use in rain (DA*)
  • Light snow (WR) – Prolonged use in snow (DA*)
  • Slightly dusty atmosphere (WR) – Prolonged use in dusty atmosphere (DA*)
  • Low temperatures use shortly (WR) — Prolonged low temperature use (DA*)

In their Lens and Accessories Catalogue , they describe AW - All Weather. This applies to all the DA* lenses plus the 560mm f/5.6.

Given the AW nature of the 560mm, which isn't a DA* lens, using "AW" is more accurate than using DA* as a designation.
