For him: Tag Heuer Link Automatic Caliber 5 Mens Watch
A really nice watch is a traditional gift that symbolizes he's reached adulthood - or at least he better be adult enough to take care of this expensive time piece! While this one is mega-nice, something a little more simple can be just as meaningful and timeless. Women also like expensive watches, and Tag Heurer makes plenty for them, too. $1,820 from watchesonthenet.com.
