I also have a Tribute to Reverso 1931 that I had engraved with a personal milestone a few years ago: my wedding date and my wife’s initials.
A lot of friends were shocked that I would engrave my new watch as they said it would be impossible to sell it off later. But that’s the whole point: this watch is MINE to keep and pass down to my children when I’m long gone. And the Reverso’s solid case back is definitely the best canvas for engravings to be done. Leaving it blank defeats the purpose of owning one IMHO.
