I am looking to replace a subdial hand for my Breiling 1191 Cadette which has a Venus 188 movement. Does anyone know the proper hole and post size needed?

 

I’m correct in assuming that the 3 o’clock subdial hand is incorrect?

 

Anyone?
I realize generic subsecond hands are readily available but would love to confirm the hole size, length, and whether a long post is needed without having to open the watch.
