It's graduation time! You all are such recommenders of jewelry ( I bought the Tiffany 1837 necklace for myself and LOVE it), so I wanted some advice. I'm trying to buy my mother a watch for her graduation, and I want to spend between $250-900 (the cheaper, always the better

) on it, so Rolex and many others are OUT!
Suggestions and recommendations? My mother loves all watches, so I won't put limits on style, although it should skew toward business dressy or dressy than super (sweats) casual.
Thanks,
Shel
