that would depend on a few factors like if the Nautilus was my only watch, my lifestyle (active or not), etc...
In this case, since I have many other watches, I would choose the Chopard since it is so unique and considered a work of art π
Just reread your description, so the Chopard was done totally on Urushi? If so, that is even more impressive for me. I also collect Japanese fountain pens from Namiki and Danitrio, and Sailor in Maki-E, Chinkin, and Urushi so I absolutely appreciate the handwork and technique ππ
