Simple ETA 2824-2 question

[RickFlorida]

Hello all.   I'm a newbie but am learning a lot in the last few months.     I have a very simple question please if anyone can chime in.

 

Do all ETA 2824-2 watch builds use this type of dial spacer ring that I found between my movement and dial?   I need to know if not always in case it effects standard stem height as I try to calculate my needed main movement ring.  (the big one that goes between the case and movement)

I found this small spacer just like it's pictured between an ETA 2824-2 and a marathon dial with the proper feet placement.    The 2824-2 has a date wheel but is not used (and will not be used in the new build either).

 

So in other words, does this picture dial spacer effect the stem height?       If this is standard then it will help me calculate the difference between a DG2813 stem height of 2.5 and the 2824-2 stem height of 1.8

 

Thanks,

Rick
