Was I duped?

I bought a brand new Omega Seamaster 300 diver last month in December from a reputable retailer here in my city. When I got it home and looked up the 8 digit serial number it said the watch production date was 2007...
That make it 14 years old ! What? Is this even possible? How could I buy a brand new Omega in 2021 that's already 14 years old? HELP.

yeah, agree with others, we need more info.

It's debatable if "New old stock" is "new"... for wrist watches that require periodic servicing and have oils for lubrication that do dry up over time, I'd argue that 13 years unsold in a dealer safe is not my definition of "new", I'd at least ask for a deep discount, if not a free service... that's if the information you are conveying turns out to be accurate.

The warranty starts from when the watch is sold (assuming proper channels) so even if it's new-old stock, if there's any issue with it then Omega will honour the warranty. I bought an older stock DeVille many years ago. It was very accurate for the first year or so. Then it started loosing several seconds a day in every position. An Omega OB with on-site watchmakers regulated it after which it was fine for several months then it started loosing time again.

It was sent away under warranty where they did "something" (meant to be partial service) which broke the crown on return. They sent a letter of apology and then performed a full service on it with the post service note mentioning the oil had dried up. Has been fine since but it does gain time now after a few years but it hasn't been in regular wear for several years either.
