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.

Orient Bambino Open Heart

Owners widely praise the Orient Bambino Open Heart for its dressy style, clean dial, and reliable in-house F6724 automatic movement with hacking and hand-winding. Reviewers and owners highlight its value proposition, with one owner noting it remains a regular wear even after acquiring pricier watches. Some owners find the build quality and stock strap less premium, with one noting the mineral crystal is prone to scratching and another that the movement can be noisy. The 21mm lug width is cited as making strap swapping slightly more complicated. Overall, owners and reviewers rate the Orient Bambino Open Heart highly for its dressy aesthetic and in-house movement at its price point.
