What people say

Owners + reviewers, side by side

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

Sternglas Naos Automatik

The Sternglas Naos Automatik is praised for its stylish Bauhaus design and solid build quality for its price, featuring a sapphire crystal and elegant case. However, some dial text is too small and slim for easy readability, and the Milanese strap and clasp are considered lower quality, with the quick-change system also not meeting the brand's advertised standard. One owner found the 38mm model lighter than expected and preferred it over a Seiko SRP703 and an Apple Watch. Overall, owners and reviewers highlight the Sternglas Naos Automatik's attractive Bauhaus design and good value, despite some criticisms of dial legibility and strap quality.

Seiko King Turtle

Owners widely praise the Seiko Prospex Sea for its excellent value, robust build, and superior lume, with many appreciating its faithful recreation of classic designs and proven movements like the 4R36 and 6R15. Reviewers highlight impressive case finishing and durability, noting that even larger models wear smaller than expected due to thoughtful case design. Some owners find the solar quartz models a great entry point, appreciating their design and solar functionality. However, specific variants receive critiques: the bracelet clasp on the Samurai is described as underwhelming, and the Sumo's bracelet width and clasp are seen as too narrow and rudimentary, respectively. The SPB183 is considered expensive for a Japanese watch, and its lume is noted as not quite matching older Seiko Monster models. The GMT function on the SPB519 is deemed less practical for serious travel, and its bezel clicks are described as quieter and mushier.

From video reviewers

The King Turtle's ceramic bezel and sapphire crystal are significant upgrades. Reviewers noted a slight price increase for these features.
