John Mayer discussed the incredible depth of this Aquatimer blue dial in a previous Talking Watches. And the dial is not the only attraction of this limited edition from IWC, made in honor of the French explorer Jacques-Yves Cousteau. This was a challenging position as Cousteau’s team actually wore most of the best diving watches of their time: Blancpain, Rolex, Omega, ZRC, Lip, Doxa… you name it. With its 42 mm compressor case and the rubber strap, the Aquatimer is not only a great diver watch, but also a very good summer watch – a lot funkier than a Submariner!  

You can find it offered on the Puristspro sales forum here for $6,250, a higher asking price than I expected, but the recent service may be a factor for the seller.
