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 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.

Tudor Black Bay

Owners widely praise the Tudor Black Bay for its comfortable wearability, robust build, and vintage-inspired aesthetics, with specific mentions of its satisfying winding feel and sturdy bezel action. Reviewers highlight the 39mm Black Bay 58's comfortable size and thinness, while others note the 41mm Master Chronometer's reliable timekeeping and magnetic resistance. Some owners find the GMT hand difficult to distinguish in low light. A recurring point of contention across multiple sources is the lack of on-the-fly micro-adjustment on the bracelet, though some find aftermarket solutions adequate. One owner reported the watch losing two minutes a day after six years, requiring a service. Overall, owners and reviewers rate the Tudor Black Bay highly for its blend of vintage charm, modern robustness, and comfortable wearability.

From video reviewers

The COSC-certified accuracy of the movement is a notable strength. The 14.7mm to 14.8mm thickness is cited as a potential drawback. Reviewers are divided on whether the newer models represent a departure from the Black Bay's heritage design.
