What people say

Owners + reviewers, side by side

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

Spinnaker Fleuss

Owners widely praise the Spinnaker Fleuss for its retro design, textured dial, and good value, with many noting it looks better in person than in photos. The watch is appreciated for its robust construction and finishing, especially when found at a discount. Some owners report good timekeeping and a decent power reserve. However, the Spinnaker Fleuss GMT is criticized by some for its large case size, which can affect proportions and numeral legibility. One owner experienced a broken crown after a fall, while another noted concerns about the acrylic bezel's durability. The lume is described as adequate but not exceptional. Overall, owners rate the Spinnaker Fleuss highly for its retro aesthetic and value proposition, particularly when purchased on sale.

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.
