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.

Seiko 5 Sports Field series

The Seiko 5 Sports Field series is praised for its value, offering an accessible explorer-style watch with a GMT complication and excellent legibility thanks to LumiBrite on the dial and bezel. The watches feature a 41mm stainless steel case, 100m water resistance, and are powered by either the 4R36 or 4R34 movement, both with a 41-hour power reserve. One reviewer notes the inclusion of a compass bezel with a lumed pearl and fully lumed Arabic numerals on the dial for the non-GMT models. Overall, reviewers consider the Seiko 5 Sports Field GMT models good value under 500 euros.
