What people say

Owners + reviewers, side by side

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

Oak & Oscar The Jackson Big Eye

Oak & Oscar The Jackson Big Eye is praised for its balanced design and fine details, featuring a prominent "Big Eye" 30-minute sub-register for improved readability, reminiscent of vintage chronographs. It is powered by the Eterna EMC 3907M manual wind movement with a 60-hour power reserve, column wheel, and flyback function, housed in a 40mm stainless steel case. This limited edition of 50 pieces was priced at $3,150 and included two Horween leather straps and a wallet. On balance, reviewers highlight the Jackson Big Eye's enthusiast-spec chronograph function and readable subdial as key strengths.

HELM Komodo

The HELM Komodo is widely praised for its excellent build quality, top-notch case finishing, clear double-domed sapphire crystal, wonderfully executed dial, and substantial lume, with reviewers noting its ISO 6425 compliance and 300m water resistance. Owners report a snappy 120-click bezel and appreciate the depth, detail, and finishing for a tool diver at its price point. Some owners find the 15.2mm to 15.5mm height makes the HELM Komodo feel thick and hefty, and the bezel ridges are noted as somewhat uncomfortable to turn, while the clasp design is also flagged as a drawback. On balance, owners and reviewers rate the HELM Komodo highly for its exceptional finishing and lume at its sub-$300 price point.

From video reviewers

The HELM Komodo's double domed sapphire crystal offers excellent optical clarity and minimal distortion. A notable weakness is its limited availability, making it harder to get than some other luxury watches. Reviewers disagree on the watch's lug-to-lug fit, with one reviewer noting it may not suit those with smaller wrists, while another reviewer does not mention this as a concern.
