Why are you guys are so obsessed with resale value? Gosh, a car is way more expensive and horrid resale value. Get it engraved. Was looking at getting a Reverso and go the same route, but somehow all those which I tried, does not fit me well.
One of the best engraver is JC Randell. Try googling him up. Not cheap, but excellent work. Enquired about my name seal on the caseback, very reasonable considering the level of craftsmanship involved.
Hope it helps. Your tribute is a beautiful piece and to have it personalised, would definitely be the jewel in the crown.
