What people say

Owners + reviewers, side by side

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

Bremont MBIII

The Bremont MBIII is praised for its versatile pilot's watch design, excellent dial visibility, and shock-resistant chronometer movement housed in a 43mm Trip-Tick case with a Faraday cage. Owners appreciate its unique origin story tied to Martin-Baker ejection seats and the brand's distinctive design language, with some noting the orange barrel accent. The watch features a 24-hour scale, 100m water resistance, and an improved Roto Click bezel. However, the "DANGER EJECTION SEAT" dial text is considered divisive, and its ETA 2892 GMT movement is not a "true" GMT as only the 24-hour hand is independently adjustable. On balance, owners and reviewers value the Bremont MBIII for its robust build and unique aviation-inspired narrative.

Marathon Steel Navigator SSNAV Auto

The Marathon Steel Navigator SSNAV Auto is praised for its high-accuracy quartz movement, with owners noting its comfort and reliable performance. Reviewers highlight its functional tool-watch appeal, featuring a sandblasted steel case, tritium tubes for constant low-light visibility, and 100-meter water resistance. One owner finds the 41mm case runs a bit small. The Marathon Steel Navigator SSNAV Auto utilizes an ETA F06.412 quartz movement with a claimed accuracy of +/- 10 seconds per year and includes a GMT bidirectional bezel. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV Auto highly for its comfortable wear and dependable, high-accuracy quartz movement.
