The 3130 is for a no date and 3135 is for sub with date function. Depends on which v10 you got(date or no date). SA is not a very liked movement because of reliability issues and part sourcing difficulties. If you have the no date a recommended movement would be at least the SH which has a better standing. If you got a date sub then VR would be the best followed by SH then SA. You can put a VR3135 in a no date but you will still have the two click outs of the stem for date and time functions, opposed to the only 1 click of the 3130 for time. If you don’t care about that then VR is the way to go
