[Question]Are Seiko hardlex THAT bad?

I recently saw a limited edition Seiko Presage in a store and it was beautiful. But the watch has hardlex glass and not saphire. Is the hardlex really that scratchable? If it is, than is it possible to change the glass to saphire in under 100 dollars? This is a really expensive watch for me and it would mean a lot if somebody can answer. Thanks.
