Looking at Vernes Nautilus design it will be more logical to use the hobnail bezel on that one too... and other two stories have nothing with screws also...
Jaguar by queen herself is incredible... would love to see it in a wristwatch... Ellipse is a great canvas for rare handcrafts with the Zebra one being a favorite of mine... this year the bald eagle looks the best in a company of insane creations...
