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.

Grand Seiko SBGJ237

Grand Seiko SBGJ237 owners and reviewers praise its impeccable finishing, Hi-Beat 36,000vph movement, and functional GMT complication. The watch is noted for its good value at €7,000, featuring a stainless steel bracelet with alternating brushed and polished surfaces, and a sapphire bezel with a day/night indicator. Reviewers highlight the lovely lume and the bezel's vintage-inspired, asymmetric color split, which uses LumiBrite for low-light legibility. The 9S86 Hi-Beat movement offers impressive accuracy of -5 to +3 seconds per day and a 55-hour power reserve. The SBGJ237 boasts 200-meter water resistance. However, the 44.2mm case size, measuring 14.4mm thick, may require slightly larger wrists, and its elevated crystal and less prominent bezel contribute to a thickness that might feel less substantial in person. Overall, owners and reviewers highly regard the Grand Seiko SBGJ237 for its combination of finishing, movement technology, and GMT functionality at its price point.
