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 Prospex SPEEDTIMER Mechanical Datsun 240Z Limited Edition

The Seiko Prospex SPEEDTIMER Mechanical Datsun 240Z Limited Edition is praised for its vintage racing concept, applied markers, and dial that shifts from cream to silver with orange accents. Owners appreciate the Datsun logo, dual crowns, and internal countdown bezel, with some noting Seiko's finishing is top-notch. However, some find the dial text cluttered, particularly "automatic 3 days," and consider the price point too high. The watch features a 42mm black-coated stainless steel case, an external tachymeter bezel, and Seiko's 8R48 automatic chronograph movement with a 45-hour power reserve. On balance, owners rate the Seiko Prospex SPEEDTIMER Mechanical Datsun 240Z Limited Edition well for its unique vintage concept and quality finishing, though price remains a point of contention for some.
