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.

IWC Schaffhausen Iw3565 Portofino Automatic

Owners widely praise the IWC Schaffhausen Iw3565 Portofino Automatic for its clean, classic dress watch aesthetic and 40mm size, which is considered perfect for smaller wrists. Reviewers and owners alike highlight its dial color in sunlight, refined dial details, and overall sophisticated appearance. One owner notes it keeps excellent time, with IWC reportedly maintaining chronometer standards. However, some find its use of an external movement and its price point less valuable compared to watches with in-house movements, with one owner suggesting avoiding full retail price. One owner reported their watch stopped working immediately after being dropped. Overall, owners and reviewers rate the IWC Schaffhausen Iw3565 Portofino Automatic highly for its classic dress watch design and wearability.
