1957 Rolex Oyster Precision 6422 - Birth Year Watch for my Father

[GSMLeonitha]

I made a promise to my father that one day I would buy him a Rolex. He doesn't have much left from his birth, so I thought that a 1957 Birth Year Rolex would hold special significance for him.

I have attached photos below from a listing of which I intend to proceed with purchase via Chrono24 in the next 24 hours. Insight specific to the 6422 would be fantastic as it is hard to come across anything substantial online, and if the photos below reveal any detail (Real/Fake/Keep an eye out for etc)

I appreciate Chrono24 has certain buyer protections, however any time saved would be great.

I thank you all for your time in advance.
