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.

Jack Mason Ellum Manual Wind

The Jack Mason Ellum Manual Wind is widely praised for its elegant, mid-century inspired design, featuring a beautiful linen-textured dial and a slim, wearable 38mm case. Owners and reviewers highlight its refined aesthetic, with some specifically calling out the gold textured dial as a favorite. The Sellita SW210-1 manual-wind movement is noted for its smooth operation and accuracy, with multiple sources reporting it regulated to within ±5 seconds per day. The watch is available at a value price point, ranging from $799 to $949 across different sources. Some owners are split on the date window, with a few finding it disruptive to the dial's design, and one commenter found the logo unappealing, while others consider the dimensions and overall package a home run. Overall, owners and reviewers rate the Jack Mason Ellum Manual Wind highly for its attractive dial and slim case at the price.
