What people say

Owners + reviewers, side by side

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

Bell & Ross BR-03 Chrono Blacktrack

Owners widely appreciate the Bell & Ross BR-03 Chrono Blacktrack for its unique square, military-inspired, stealthy all-black ceramic design and dial styled like a motorcycle's cooling grid, finding it a refreshing alternative to common styles. Reviewers note the watch's surprising wearability, particularly with flared straps, and its futuristic design with personality. Accuracy figures vary, with one source reporting +10 seconds per day for the ETA 2894-2 based BR-CAL.301 movement, which has a 42-hour power reserve. Some owners criticize the use of rebranded base movements and significant depreciation, while one reviewer found the padded, quilted strap less comfortable than usual and noted poor lume. On balance, owners and reviewers rate the Bell & Ross BR-03 Chrono Blacktrack well for its distinctive, personality-filled design.

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.
