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 Pro Automatik

The Sternglas Naos Pro Automatik is praised for its slim 9mm case and Bauhaus dial design, featuring clear hour markers and a framed date window. Owners note the upgraded Miyota 9015 movement with a 4Hz beat rate. Accuracy is reported as -10/+30 seconds per day, which is not ideal for precision enthusiasts. The five-link bracelet's lack of fitted end-links and the optional bracelet's chunkiness are flagged as areas lacking refinement. Overall, reviewers highlight the Sternglas Naos Pro Automatik's improved wearability and premium feel at its price point.

From video reviewers

The Bauhaus design is a strength. The value proposition is a weakness.

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.
