Zodiac 76 Stem replacement

[bill2thakr]

Hello All! First time poster here and new member.
I have a Zodiac wrist watch which on the rotor says it is a 76. I bought a winding stem that was supposedly for a model 72 which the 76 is based on. However it did not fit in the winding stem entry point, the replacement was a fraction too big.

Does anyone have detailed measurement of what the winding stem should measure?

Is it possible the rotor got changed and it isn't a 76?

Any Help or suggestions are welcome!

I Think I posted in the wrong group?

I figured out how to move it!
