Hmmm...what to get my SF (Sweet Fiance)??

So my fiance got me the most amazing engagement ring. Its all I ever hoped for! The wedding planning is going fantastic - we didn't even fight too much over the guest list! (I was shocked) I know its proper to give him a gift on our wedding day. I'm just really having a hard time deciding what to give him. I know I want it to be very special. He loves Sports, Fishing, Nice Watches, etc. Needless to say planning a wedding - the funds are somewhat tight. I need some help here! All suggestions are appreciated...its getting down to the last few months. HELP!
