Purchased this for my dad whose PAG-40 watch band had deteriorated and broke.  The band fit perfectly and was easy to install.

A couple of notes that might help:

1.  The band is held in place by a screw that screws into a pin and not the watch itself.  You'll have to use two screwdrivers (one on each side of the band you are removing/installing) to take the screw out and to reinstall.  If you unscrew one side, the whole pin pivots, so you'll just rotate it and never get the screw out.
2.  The band itself is all plastic, unlike the cloth/pleather combination that came with the watch.  This is a good thing.  The plastic lining on the original band wears out very quickly and a the threads fray out on the original band.  This replacement band is all plastic, of good quality, and completely waterproof.

Product shipped and was received promptly.  Would order again.
