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.

Nivada Grenchen Chronomaster Valjoux

The Nivada Grenchen Chronomaster is praised for its vintage aesthetic and versatility, with the Aventurine Blue variant offering a unique starry dial and world time bezel. Owners note the sub-dials are small and difficult to read, and the Sellita SW510 movement exhibits rotor wobble and hand play. The $5,000 price point is a significant increase from previous reissues. Overall, owners rate the Nivada Grenchen Chronomaster highly for its vintage aesthetic and unique dial options, despite some concerns about sub-dial legibility and movement characteristics.
