5130P education, please

What’s the difference between 5130P-001 and 5130P-020? Also, I have seen some 5130P with the Calatrava cross deployment buckle, while others have a simpler fold over clasp (even under the same full ref, eg 5130P-001). Do you know which model used to be sold originally with the Calatrava cross buckle?

the last three digits refers to the dial ,I think they changed the city ring due to changes in city names in certain timezones.
