What people say

Owners + reviewers, side by side

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

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.

Sinn U2 S (EZM 5)

The Sinn U2 S (EZM 5) features good, solid lume that remains readable throughout the night, though some owners find its initial brightness less intense than other dive watches. Reviewers highlight its excellent legibility due to a high-contrast dial and large hands, housed in robust German submarine steel with a scratch-resistant Tegiment-treated bezel. On balance, owners and reviewers appreciate the Sinn U2 S (EZM 5) for its robust construction and clear dial legibility.
