I'd never really thought that much about crowns before I got my Archimede, I think they tend to get overlooked a bit in favour of dials and hands and all that good stuff. It may just be that I've never had a crown I've fallen in love with, but I'm absolutely smitten with the one on the Pilot. It's so big, so beautifully designed and machined, and so wonderful to fiddle with. It's made me think about the crowns on all my watches and consider them a lot more when looking at watches I don't own.
Here's mine, show me your faves!
