What people say

Owners + reviewers, side by side

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

AVI-8 Spitfire Lock Chronograph

Owners widely report AVI-8 watches offer a compelling design and are decently well made for the price. The AVI-8 Spitfire Lock Chronograph features a 42mm stainless steel case with curved lugs, a bi-compax meca-quartz movement, and a mineral crystal, with design elements inspired by Supermarine Spitfires. One owner notes that AVI-8 watches are "something different" and "decently well made," though not of "insane quality." On balance, owners and reviewers appreciate the AVI-8 Spitfire Lock Chronograph for its unique design and value proposition.

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.
