What people say

Owners + reviewers, side by side

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

Bremont Altitude Chronograph

Owners note faint marks on the case sides and back, with minor wear and creasing on the strap. Reviewers flag the "DANGER EJECTION SEAT" wordmark on the dial as a divisive design choice that disrupts the MB series' usual stark tone, though they praise the improved smoothness and click precision of the Roto Click rotating bezel. On balance, the Bremont Altitude Chronograph elicits mixed reactions, with design elements like the dial text being a point of contention for 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.
