I would commission one-off pieces from manufacturers such as Patek, Lange, Journe, Piaget, Panerai, Hajime Asaoka, etc. And, yes, I would want a Panerai Cali dial. Probably in a 42mm Radiomir titanium case. Every piece would be exactly what I want. I would probably have eight watches all together. They may all be different metals as well. Stainless steel, platinum, titanium, tantalum, red gold, etc. Probably have a Patek Calatrava in stainless steel. Stuff like that. Nothing too complicated.

I'd buy a lot of watches as gifts though.
