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.

Zelos Comet 39

Owners widely praise the Zelos Comet 39 for its wearable 39mm size, thin profile under 10mm thanks to its manual-wind Sellita SW215 movement, and its captivating dial with a deep starburst effect. The winding action is described as a joy, and the watch is considered a stunner for its price, blending modern and vintage aesthetics. Some owners note frustration with Zelos's limited production runs leading to quick sell-outs. One owner found the logo childlike, while another experienced strap-rubbing issues with the short lugs, which were resolved with a Milanese bracelet. Overall, owners and reviewers rate the Zelos Comet 39 highly for its excellent value and striking dial design.
