Clearly it's not a watch you intend to sell, so good for you for starting a family tradition (not sure if that's the right word, but 'heirloom' doesn't seem to fit right). The work looks clear, clean, and discrete. I don't think you jeopardized the watch at all; you added to its awesomeness. Your son will no doubt treasure it when he inherits it.
This was given to my grandfather after 25yrs at his work. He wore it all the time (the man - and the company - had taste). My father had it for years after Grandad died. It was passed down to me not so long ago - and I gifted one of my watches up to dad later. For me, the engraving makes this watch (the splash of red on the dial is in good taste too); a piece of my grandfather I carry with me often. Some watches may come and go, but this one will never leave my family... at least it better not!
