Citizen 5500 where to get the proper gasket

[MF60]

I’ve successfully replaced the batteries in about 10 quartz electric watches that were collecting dust.  The last one I worked on is this Men’s Citizen gold tone day date 5500-s24485.  I was not pleased with the fit of the case back and when I looked closely the gasket is damaged.  I own two of these and this is the older.  When I took it in to J C Penney’s a long time ago,to have the battery replaced, the repair guy said it was no longer working and I bought an identical one. Now I think I know why it was not working because the crown stem was hard to turn.  Worked well no.  
Where would I go for gaskets and how do I find a part number? I’ve not had luck with a Google search.

Also on the open case back there’s the word “push” with an arrow. For what is that instruction provided ?

You really can't tell if it's a crown gasket issue unless you take the movement out as it could be a movement issue. And often times people just replace the crown rather than the gaskets. Or you can buy generic Assortments of crown gaskets and use one of those.

Who trying to tell you something Which is how to get the stem out. Often times the part is sort of hidden and to help people out the pill you where It is. But sometimes only reveal itself if the stem is in the right position.

Then you may find the attached technical guide of use
