Sadly, there's no AR (anti-reflective) coating on the crystal. However, this hasn't proven to be too much on an issue since it's a reasonably high contrast, white indices on black, dial.
 
After trying it on the original nylon band, on nylon NATO G10 bands and on leather NATO G10 bands, I've decided I prefer it on the stockman's band (excuse the bad phone photos).
 
 
Here's the aforementioned Timex Weekender on an 18mm leather NATO - note that these look better and more in proportion on an 18mm band than on the recommended 20mm band.
 
My basic watch rotation - nothing really spectacular, but I wear them often. L to R (top) - Cheap and nasty Gruen quartz oversized submariner (42mm inc crown) on a 20mm grey Zulu NATO. Although it's nasty, it's a reliable quartz and has survived multiple dunkings - great beater. Next is an Omega Aqua-Terra GMT automatic (40mm inc crown) on a 20mm German-made leather G10 NATO which I have "vintagized". Next is a standard base model Casio G-Shock Mudman with homemade band adapters on a black 20mm G10 NATO. Next to that is the Seiko 5 automatic field watch on a heavy-duty leather stockman's band with swiveling cover. IMO the Seiko, being such a small watch, is well suited to wearing on a bund style band like the stockman's. L to R (bottom) Pair of 38mm Timex Weekenders. Black face Weekender on a russet brown 18mm leather G10 Nato. Cream face Weekender on a seal brown 18mm leather G10 Nato. I prefer the cream face watch. Both are rated water resistant for washing up, rain, showering, surface swimming, etc. But will most likely survive snorkelling and pool diving as well. Mine has been whitewater kayaking and has Eskimo rolled without issue.
