Had no idea Cartier made anything like this, looks fantastic and very unique.

My vote is Black OP36 or an Explorer I. Since you mentioned price of 1016s (personally I just don’t like the feel / build of vintage watches after being used to modern ones), there’s a lot of microbrands that do nice watches which reference the 1016 and similar designs like the Lorier Falcon and Smiths Everest. I tried on the Lorier at Wind Up in NYC and liked it much better than I had expected.
