yeah YMMV, but Hardlex can get scratched. my skx007 has a big scratch on the crystal (hit it on one of those steel door knobs), and if you look close there's several little micro-scratches. I've debated about replacing the crystal, but I decided to just let it be my beater watch. that being said, you'll find several people that have had Seiko's for years, and they never got scratchedAll the seiko watches in that price range have Hardlex crystal, not sapphire.
Did some research on it. Seiko uses Hardlex on their diver watches because it doesn't burst apart on hard impact, like sapphire would. Hardlex will crack but not break apart. The trade off is that Hardlex is easier to scratch than sapphire.
it is true that Hardlex is less likely to crack and break, because it is softer (like a tree that bends in the wind). but it's the kind of thing where if your watch is taking an impact strong enough to break sapphire, you probably got other shyt to worry about. most examples I've seen of sapphire getting damaged come from a car accident, being dropped off a building, or some crazy shyt
most watches in your price range (< $250) are going to have a Hardlex or other mineral crystal. but there are a few with sapphire, and you'll find a lot more in the $400+ range
