What people say

Owners + reviewers, side by side

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

Spinnaker Hass Automatic

The Spinnaker Hass Automatic is a 43mm watch featuring an NH35 movement and sapphire crystal, with owners highlighting its beautiful dial. Some find Spinnaker watches, including this model, to be on the thicker side, with one owner describing the Hass X MCS Blue Fade variant as comically large and chunky. The Spinnaker Hass Automatic was offered at $445 USD as part of a special collection with customized elements, and a limited edition of 200 pieces was also available for $195 shipped. On balance, owners and reviewers note the attractive dial as a key positive, though some express reservations about the watch's thickness.

From video reviewers

The dial's recovered marine plastic construction with textured finish provides distinctive material differentiation at the entry-level dive watch price point, and the sapphire crystal with anti-reflective coating ensures strong on-wrist legibility. The 300m water resistance and automatic movement deliver capable specifications, though bracelet quality and fit remain underspecified across reviews.

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.
