With a 42mm case, the redesigned IWC Aquatimer Automatics are the smallest member of the new Aquatimer family. But as you can see these new references should wear quite well! I think they look great with the new internal/external bezel system and their pure 3-handed dials. One small technical improvement is that the water pressure rating has been from 120 meters to 300 meters, same as the Aquatimer Chronographs. Again as a reminder see my 2014 IWC Aquatimer Collection overview for more details on the new design elements.
