Weddingbee boards

I am wanting to get my dad an engraved pocketwatch for my wedding day.  What is something great that I can engrave on it...something fun/and not cheezy.  My dad and  I have an awesome relationship..and I'm his only daughter....

 Please help as I really want to get this ordered but can not think of anything great!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I did the same thing for my dad!  I had "Thank you isn't enough..." engraved on his, because it's true!  Words can't adequately thank him for everything he has done for me.  I also gave him a very heartfelt letter along with the watch to explain why I did it.
