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.

Hamilton Jazzmaster Skeleton Auto

The Hamilton Jazzmaster Skeleton Auto is praised for its redesigned dial that balances complexity and legibility, forming an "H" logo and highlighting the H-10-S movement. Owners appreciate the 80-hour power reserve and the seamless blend of the bracelet with the lugs. The watch is available in 40mm and 36mm sizes, with prices ranging from A$1,925 to A$2,200, and features 50m water resistance. Overall, owners and reviewers rate the Hamilton Jazzmaster Skeleton Auto highly for its distinctive dial design and impressive power reserve at its price point.

From video reviewers

The 80-hour power reserve from the H-10 automatic movement is a notable strength. Water resistance to 5 ATM is considered on the lower side for the price point.
