Antiquorum Auction-What year is it?

[ROGERB]

So I (and I'm sure many others if this is where you hang out) enjoy seeing vintage pieces out there in the market. Hodinkee has a regular post on Friday's of a array of what they think are interesting. This morning they are showing watches from different sources one being a 1960 Tudor 7909 with a Sikorsky Aviation logo and presentation engraving on the back. The watch and the person it was given to is a great back story and was presented for 25 years service in 1956. Watch is being auctioned through Antiquorum Nov 10th. You'd think someone over there would notice that they have the watch year 4 years after it was presented
Serial number clearly puts it in late 55 early 56. I guess just another example of diligence skewed
