Of the watches in your selection, like others I would vote for the IWC. (Chronoswiss is not the brand you want to spend your hard earned money on.)
Like others, I would also strongly recommend a JLC Master Control over any of the four choices in the initial post. JLC is a storied watchmaker that produces superb in-house movements and elegant designs, and probably provides the best value of any fine brand. Lots of choices in your price range.
