Seestern S456 GMT

Owners widely praise the Seestern S456 GMT for its exceptional value and finishing that exceeds expectations, with one owner noting its accuracy surpasses that of their Seiko 5. The dial displays a pearl-like rainbow effect. Some owners would prefer a bidirectional bezel over the current unidirectional one. The Seestern S456 GMT features an NH34 movement, a 39.5mm case, sapphire crystal, and an adjustable clasp. On balance, owners rate the Seestern S456 GMT highly for its impressive finishing and value proposition at its price point.

From video reviewers

The watch features stunning, detailed finishing that is difficult to top. Reviewers did not reach a consensus on any weaknesses.

Sternglas Sedius

The Sternglas Sedius is widely praised for its harmonious blend of Bauhaus minimalism and Art Deco elegance, featuring a well-balanced sector dial and a smooth-sweeping seconds hand from its Seiko VH31 meca-quartz movement. Owners and reviewers note its pleasing wearability due to the case shape and slender lugs, and it is considered an affordable option with a good price-performance ratio. One reviewer flags legibility issues on the black dial variant, while the blue-on-white offers crispness. The Sternglas Sedius lacks a date complication and features a double-domed sapphire crystal. Overall, owners and reviewers rate the Sternglas Sedius highly for its classy Art Deco aesthetic and value.
