I have the same 25 year old Mitutoyo with the tiny numbers. Its no more accurate than the $10 chinese ones from Canadian tire or who ever puts them on special. If the $10 one falls on the flour I don't cringe, if it gets coolant I don't cringe, I can wipe off the dust and grime and I don't cringe if the bezel gets scratched. In short a calliper isn't a precision instrument, there is a BIG difference in chinese and good micrometers but a calliper is a calliper.
Free advice is worth exactly what you payed for it.
