Buying a 5-year old new in box datejust?

[holacicas]

Hi guys, after hanging around in the forum for last few years I've finally saved up enough to buy a 36mm datejust. While I'm browsing for what's on the market, I found a seller selling a never-worn datejust that was manufactured in 2012 (W116234BLSO, seller's disclosure). How concerned (if at all) should I be with the production date that was 5 years ago? Since it's my first time buying a rolex, and also since I've actually never seen others disclosing the production year beforehand, I'm curious what the market practice is (does official dealers also sell watches that are manufactured a few years back if they are of same model?). Is the 5 year gap is something that I should be concerned about in buying high-end watches?

Thank you!
