Owners widely praise the IWC Schaffhausen Iw328801 Aquatimer Automatic as a beautiful, solid, and hard-wearing watch with great lume and a unique, functional bezel. Some owners find the 42mm case chunky and note that non-removable bars limit strap options, while one reviewer suggests the utilitarian and angular look, combined with a non-tapering bracelet and substantial weight, indicates a need for refinement. The movement is an automatic 32111 caliber with a 120-hour power reserve. On balance, owners and reviewers rate the IWC Schaffhausen Iw328801 Aquatimer Automatic well for its robust build and functional bezel system.
