Looking for a new crown

Just got this Admiral which has brassing on the crown. Here is my watch and current, most likely original crown



Here is a crown on Ebay that i am looking at. Thw seller states it is "original." The logo looks funny to me, and I cannot tell if it is the photo, but it looks suspicious as an aftermarket. Also, there are more teeth on the crown than on my worn crown. So my question is, does this look like a good replacement crown? Also would folks keep the original crown with the brassing?

I do not have a Rosetta Stone for Squirrel Talk translation to English. Does the above post mean the Ebay crown is fake?

The Longines girls think it`s ok
