Serial number and model number

[Ony]

Hi, I bought a 1972 (based on the serial no.) Rolex Oysterdate Precision. I brought it to the Rolex Service Center to have it serviced. After more than 2 weeks, they said according to the main office, the serial number of my watch DOES NOT MATCH the model number. That is why they cannot service it.

But they said that doesn't mean my watch is fake.

So I then bought my watch to a very experienced Rolex technician here and after examining my watch he said all parts seemed original.


Any thoughts on this?

Thanks.
