Looking for some advice?

I have seen a Boeing Model 247 TI-GMT at a local pawnbroker, it's priced at 3000 which sounds reasonableand is a 2015 model? The only issue is, although it comes with a case there does not appear to be any additional paperwork apart from the back page of the booklet showing where and when it was bought. How important are the 'papers' or should I just go for it? The watch appears to be in lovely condition with two straps (fabric and leather)?

Just wondering what owners felt?
