The crown of the watch is that part of the watch that you use to wind the watch and also to set the time. I have a standard style crown with my logo, sometimes called a signed crown, that I use in a majority of my watches. Occasionally I might use a tapered crown or an onion style crown. The onion style crown is typically only used on my 45mm case (aka The Rydian case).
Here are a couple pictures of the crowns I use:
