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 Naos Großdatum

The Sternglas Naos Großdatum is praised for its Bauhaus aesthetic and value, with one owner finding it an affordable alternative to other designs. However, some owners report it feels underwhelming and cheap, with a printed-on face, small font, and toy-like hands, and find the strap to be of poor quality. The watch features a 38mm stainless steel case, an Alabaster dial with beige LumiNova, and a Seiko TMI VJ76 quartz movement rated for -20/+20 seconds per month. On balance, owners and reviewers are divided, with the primary point of contention being the perceived quality and aesthetic execution of the Sternglas Naos Großdatum.
