What people say

Owners + reviewers, side by side

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

Formex Essence ThirtyNine

The Formex Essence ThirtyNine is praised for its impressive build quality and value, featuring a patented case suspension system for comfort and protection. It houses a COSC-certified Sellita SW200-1 movement with a 38-hour power reserve and a tool-free strap quick-release system. A minor inconvenience noted is the specific closing order of the clasp. On balance, reviewers rate the Formex Essence ThirtyNine highly for its comfortable wearability and excellent value at its price point.

From video reviewers

The case suspension system enhances comfort and the COSC-certified movement is a strong feature. The bracelet exhibits noticeable rattle. Reviewers disagreed on the ideal case size, with some preferring the 39mm and others the 41mm.

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.
