My vote is mesh or black NATO. Six of one...
And now for something I don't think I have seen in this thread, a watch with one hand, the Pita Barcelona Minimal.
I love the idea of a single hand that takes 12 hrs to complete one revolution. This one is WAY out of my budget at $11K, but I have found a similar model by Schauer for under $4K.
I also like this regulateur.
What do y'all think of these unusual designs?
