1981 datejust 16013 no “Swiss” on Dial.. Worth ???

[Pizzatele]

Fellow members,
I purchased a 1981 Rolex model 16013 overall condition I would put at 6 or 7. It’s used but very clean. Some small scratches on crystal, it been polished, the Rolex band has some stretch, overall very clean but no doubt they it’s used. My question is this... watch has dial that does not have the word “Swiss” at the six o’clock position. I paid $2700.00 for the watch. How much does the fact that the dial has been redone or replaced effect the value of the watch. The Lume does not work. From what I have read that is expected from a 38 year old watch, so I do not believe dial is new. What do you guys think this watch is worth. Seller is offering full refund but I have seen this same exact watch sell for $3300.00 to 4000.00 plus. What is your opinion.
Thank you,
Joe
