Now how about a Flyback to celebrate the reunion? =)
Sorry, silly joke...but all kidding aside, I think your son will love the gift. It must be nice to receive such a valuable gift at a time when many of us (or was it just me) are struggling to make a complete transition to adulthood. The Flyback is also versatile and will serve him both in formal situations(perhaps a movie premiere - especially with a classy croc dial) and at play for years to come.
Congratulations on such a nice purchase. Please share some nice photos.
