Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Formex Essence ThirtyNine is widely praised for its build quality and value, featuring a patented case suspension system for comfort and protection. Reviewers note its 39mm case with a 10mm thickness and 45mm lug-to-lug distance, housing a COSC-certified Sellita SW200-1 movement. It includes a tool-free strap quick-release system and a patented micro-adjusting bracelet for comfort, with pricing around $1,280-$1,390. One minor inconvenience noted is the clasp's specific closing order. Overall, owners and reviewers rate the Formex Essence ThirtyNine highly for its comfortable wearability and excellent value proposition.
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.
Owners and reviewers widely praise the Longines ULTRA-CHRON CLASSIC for its faithful retro design, high-beat 5Hz movement offering superior accuracy and a smooth seconds sweep, and its value proposition for a new 5Hz chronometer-certified watch. The bracelet is noted for comfort and a user-friendly micro-adjust system, while the dial's indices are described as having a striking sparkle. Some owners find the design dated, and one reviewer points out the dial lacks luminescence and the 50m water resistance is not exceptional. Opinions are split on sizing, with some finding the 40mm variant wears larger than expected and recommending the 37mm for most wrists. Overall, owners and reviewers rate the Longines ULTRA-CHRON CLASSIC highly for its blend of vintage aesthetics, modern high-beat movement performance, and strong value.
