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.

Spinnaker Bradner GMT

The Spinnaker Bradner GMT is praised for its awesome lume and comfortable wearability, with one owner noting the rubber strap is very comfortable and the beads of rice bracelet fits well on smaller wrists. Some find its 15mm thickness and bold colorway may not appeal to everyone, and one owner views it as more of a casual GMT with tool-watch styling than a diver. Overall, owners rate the Spinnaker Bradner GMT highly for its value and comfortable wearability.
