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.

Yema Superman Tourbillon CMM.31 Limited Edition

Owners praise the Yema Superman Tourbillon CMM.31 Limited Edition as an incredible and crazy watch, appreciating its unnecessary tourbillon complication and impressive specifications at a remarkable price point. The titanium construction contributes to comfort despite the 43mm case size. One reviewer notes the bracelet clasp's extension system is somewhat crude. On balance, owners and reviewers rate the Yema Superman Tourbillon CMM.31 Limited Edition highly for its compelling tourbillon feature at an accessible price.
