I prefer the two symmetrical crowns at 2 and 4 o'clock design but it sure is cool with three crowns on a watch, mine here:

I like it. Pity that the case is chrome plated ,the rest could have been fixed.
It's true, I've fallen for so many lovely pieces only to back away because of a plated case. For me it's less about the aesthetic and more about the plating itself, and sometimes the underlying material, causing allergic reactions against my skin. Not a gold man so Stainless only for me.
The case back is made of SS but for sure some of the parts of the lugs will touch the skin. If I understand correctly it is brass that was commonly used as base material in chromed watches. And that is why it gets so ugly when chrome wears out and dark brass starts be visible.
