as they all hide their real self behind a discreet dial. I would choose the Gronefeld Remontoire Hodinkee from your selection because it is the only one that fits my wrist and also I consider the movement of Gronefeld one of the most spectacular looking movements ever made, even if not as complex as a tourbillon, triple split or a minute repeater. But if money was no object, I would have to opt for Patek's 3939 as mentioned by several others. Minute repeater and tourbillon behind the case back in a 34mm diameter watch spells pure genius to me!

A simple looking dress watch

A mesmerising movement!
