my brother has a 220 so i know a little bit about it. they were made for three years in lots of 400, 400 and 500. after the third year panerai developed a new style bracelet and the 220 was retired. they now have the 299. same watch, but with the new style bracelet. don't worry though ... the old style bracelet (yours) is much nicer and prefered by most risti's. i wouldn't say the 220 will appreciate over time but it's held it value pretty well simply because there are only 1,300 out there. having said that, i would wear the watch without worry. it has a lot of polished areas that will mark easily, but will also give it some character. if and when you're ready to hand it down to one of your sons, send it in for a service and polish and it will look as good as new. congrats again on a beautiful new rugged watch!
