What people say

Owners + reviewers, side by side

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

Bremont Supermarine 300M

The Bremont Supermarine 300M is praised for its comfortable 40mm and 42mm case sizes, with owners noting the 42mm wears well on smaller wrists due to its lug design. One owner highlights the 13mm thinness of the 40mm case, considered compact for a 300m diver. The watch is priced at $1375. On balance, owners and reviewers appreciate the Bremont Supermarine 300M for its wearability and compact dimensions, especially for a dive watch.

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.
