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.

Santurce Guaraguao True GMT — Automatic Pilot Watch

The Santurce Guaraguao True GMT — Automatic Pilot Watch utilizes the Miyota 9075 automatic true GMT movement. Owners note the Miyota 9075 is an affordable true GMT movement. One owner found the 15mm thickness to be substantial, though the 38mm diameter made it wear well; another user considered the lack of a date window a dealbreaker. On balance, owners find the Miyota 9075 movement appealing for its true GMT functionality at an accessible price point.
