Reviews

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

Borealis Watch Co. Lusitano

Owners widely praise the Borealis Lusitano for its outstanding lume and high-quality bracelet, with one owner noting a comfortable fit. The Miyota 8315 movement is a point of discussion, with one owner finding it disappointing while another considers it superior to Seiko's 6R series. A single owner reported misaligned bezel indices and the need to regulate the Miyota 9015 movement. On balance, owners find the Borealis Lusitano offers good value, with its strong lume and bracelet being key selling points.

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.
