What people say

Owners + reviewers, side by side

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

Marathon OSAR-D (Original SAR with Date) Automatic 46mm

The Marathon OSAR-D (Original SAR with Date) Automatic 46mm is widely regarded as a rugged and legible timepiece, featuring a familiar geometric dial with MaraGlo lume and a white dial with applied hour markers that enhance legibility. Owners and reviewers note its 300-meter water resistance and the reliable Swiss-made Sellita SW200-1 automatic movement with improved shock protection. The watch is described as large, thick, and heavy, with some owners finding it comfortable on the wrist while others note its substantial presence, particularly at a table. Overall, owners and reviewers appreciate the Marathon OSAR-D (Original SAR with Date) Automatic 46mm for its rugged build and excellent legibility.

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.
