What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

IWC Schaffhausen Iw328801 Aquatimer Automatic

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

Sternglas Marus 2.0

Owners widely praise the Sternglas Marus 2.0 for its well-built, heavy case and excellent bezel action, which is considered superior to some competitors. Reviewers note the refined case and luminous dial markers, while the green dial stands out from other divers. The Seiko NH35A movement offers accuracy ranging from -20/+40 seconds per day. One reviewer desired a slightly larger screw-down crown. Overall, owners and reviewers rate the Sternglas Marus 2.0 highly for its robust build and standout dial at its price point.

From video reviewers

The Seiko NH35 automatic movement is a shared strength. Reviewers did not reach a consensus on any weaknesses.
