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.

Redux Zero-Hour

Owners widely praise the Redux Courg Zero Hour 39MM for its robust, utilitarian design inspired by pilot and dive tools, its lightweight Grade 5 titanium construction, and its comfortable wearability. The proprietary RDXB1 lume is noted for its bright initial glow, though it fades quickly. The Seiko NH53A or NH35 movement is generally considered reliable. However, multiple owners report a flimsy or fragile crown stem, and some describe the unidirectional bezel as having play or being able to rotate clockwise by one minute, though one owner reported a tight bezel with no play. The 39mm case size is considered good by some, while others find it small for larger wrists or note it looks large, with some desiring a 42mm option. One owner found the titanium finish looked slightly cheap and wished for a bezel insert. The dial is described by one owner as too busy for easy reading without glasses. The Redux Courg Zero Hour 39MM is available for $300, down from an original price of $507.
