What people say

Owners + reviewers, side by side

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

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.

Tissot Gentleman Open Heart

Owners widely praise the Tissot Gentleman Open Heart for its versatile dressy-sporty aesthetic and elegant sunburst dial finish, with one owner preferring its less shiny blue dial compared to other versions. The watch offers excellent fit and bracelet adjustability, and its modified Powermatic 80 movement achieves COSC-level accuracy of -3 to +5 seconds/day, though the seconds hand movement is slightly less smooth at 6 movements per second. However, one owner reported the watch arrived non-functional, requiring a return due to an inoperable movement. On balance, owners rate the Tissot Gentleman Open Heart highly for its aesthetic appeal and accurate timekeeping, despite a reported instance of a faulty movement.
