Reviews

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

Formex Essence ThirtyNine

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.

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.

Hamilton Jazzmaster Thinline Auto

The Hamilton Jazzmaster Thinline Auto is widely praised for its gorgeous, stunning, and captivating dials, particularly the champagne and burgundy variants, and its thin, comfortable, vintage-inspired design that fits well under shirt cuffs. Owners appreciate its clean, simple aesthetic, often noting the beauty of its applied indices and dauphine hands, and the slim profile afforded by its movement. Some users find the absence of a second hand liberating for quick setting and avoiding accuracy checks. However, opinions are mixed on its thinness, with some finding it too thin for their preference. The ETA 2892-A2 movement's rotor noise is noted by several owners as audible due to the thin case, and the winding feel is described by one owner as unrefined. The small crown is also flagged as difficult to manipulate, and the OEM strap is disliked by one owner. One source mentions the polished case may show light swirlies.

From video reviewers

The slim case profile and affordable price point are consistently praised. Reviewers noted the absence of a second hand.
