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-X1 TOURBILLON ROSE GOLD DIAMONDS

The Bell & Ross BR-X1 TOURBILLON ROSE GOLD DIAMONDS is a luxurious, technically advanced timepiece with a modern, drone-inspired design and a skeletonized movement. Owners and reviewers highlight its unique, Transformer-like evolution of the BR 01, featuring switch-style or rocker-style chronograph pushers and a diamond-set bezel that some describe as fitting for a Bond villain. The watch houses a manually wound caliber BR-CAL.283 movement with a 4-day power reserve, operating at 3Hz, and includes time, subsidiary seconds via the tourbillon, a 30-minute monopusher chronograph, and a power reserve indicator. While the overall quality is high and the rose gold trim transforms it into an elegant watch, one reviewer notes its base movement is not in-house. On balance, the Bell & Ross BR-X1 TOURBILLON ROSE GOLD DIAMONDS is highly regarded for its futuristic design and precious materials.

Sternglas Naos Pro GMT Automatik

Owners report the Sternglas Naos can feel underwhelming with a cheap feel and hands resembling office printer output, with some finding it wears smaller than expected and looks like a toy, though others appreciate its understated design. Reviewers highlight the Argo Automatic variant as a compelling sub-€400 mechanical watch with a colorful dial and practical date wheel, suitable for new collectors, featuring a 38mm case and a Miyota 8215 movement. On balance, the consensus is that the Sternglas Naos offers a mixed ownership experience, with its value proposition and entry-level appeal being its strongest points for some.

From video reviewers

The Sternglas Naos Pro GMT Automatik features a clean Bauhaus design that sets it apart from other GMT watches. A notable weakness is the watch's bezel action, which is not as smooth as some reviewers would have liked. Reviewers disagree on the watch's case size, with one reviewer stating it's slightly larger than the original Naos Automatic, while another reviewer doesn't mention this aspect at all.
