What people say

Owners + reviewers, side by side

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

Nivada Grenchen Chronomaster 38mm Automatic Chronograph

Owners widely appreciate the Nivada Grenchen Chronomaster 38mm Automatic Chronograph for its perfect 38mm size and faithful vintage reproduction, with one owner finding its worn bezel enhances its appeal. Reviewers praise its unique "baked" tropical dial, which mimics patina without the risks of a vintage piece. However, one owner reported a feeling of poor construction and lighter-than-expected weight, while another regretted the automatic caseback causing the watch to sit high on the wrist. The chronograph's 100m water resistance is noted as a slight limitation. On balance, owners and reviewers rate the Nivada Grenchen Chronomaster 38mm Automatic Chronograph highly for its excellent vintage aesthetic and unique dial that offers the enjoyment of a tropical watch without the associated risks.

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.
