What people say

Owners + reviewers, side by side

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

Sternglas Marus

The Sternglas Marus is widely praised for its well-built, heavy feel and excellent bezel action, considered the best in its price range. Despite its 42mm diameter and 52mm lug-to-lug, owners report it fits surprisingly well on slim wrists. A reviewer notes the short seconds hand as a drawback, but highlights the watch as a fun, affordable starting point for a collection, featuring a vibrant Pepsi bezel and an anthracite dial that shifts in appearance, powered by a Miyota 8215 movement for €399. Overall, owners and reviewers rate the Sternglas Marus highly for its robust build and superior bezel at its price point.

Sinn U18

The Sinn U18 is praised for its unique deep blue/green dial with three-dimensional oxygen bubbles that change with light, and its comfortable, easily adjustable bracelet. Owners find the watch stunning and a piece of history, appreciating the refined hands. The Sinn U18 features a 44mm, 15.5mm thick case made from German submarine steel, offering a 2000-meter dive specification and Sinn's Ar-Dehumidifying technology, powered by a Sellita SW300-1 movement. The case thickness is apparent, and the watch comes as a complete set with box and papers for $3,000-$3,680. On balance, owners and reviewers rate the Sinn U18 highly for its striking dial and robust build.
