Engraving on the Case back

I almost bought a 2022 Nomos Club Campus 38 Night until I realized that there is a name engraved on the case back (Roberto). This has instantly put me off. The price is really attractive and the watch is in excellent condition but since I've got to know about the engraving, something has just changed. The second thing that's bothering me is the possibility of a negative impact on the resale value of the watch. Should I go for it or let it pass?
