Would someone be able to tell me the correct Rolex part number for a Ladies Date 6916-2035 (vintage 1981) mainspring? Searching Google, I found two numbers for the 2030-2035; 4419 and 4420. Which is the correct one? Thanks

Mainsprings are offered in what is call weak and standard strength.Calibre 2030 is the base calibre model which most all of the parts list is based on the 2035 is a calendar model so only those parts will be listed for it. They essentially are the same movement but with calendar add-ons. Either mainspring will work but standard is what I use mostly. That would be part number 4419 hope that helps Rik the watchmaker
