Love everything about the watch EXCEPT for the fact that despite only three months of gentle use, the "mineral crystal" as described in product specs has scratched up so much it's getting almost impossible to read the time! Very disappointed with this flaw, which was noted by several other reviewers.
Not "mineral crystal" as described in specs-- the face scratched up immediately!
