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.

Fortis Marinemaster M-40

Owners praise the Fortis Amber Orange for its gorgeous appearance and strong wrist presence, noting its crazy lume and 70-hour power reserve. The Doxa SUB 300T, described as having a superb, eccentric design with a highly legible dial and functional no-decompression bezel, uses an ETA 2824-2 movement. However, the SUB 300T's 42.5mm case wears large and its 14mm thickness is not ideal for dress shirts, though it boasts 1,200m water resistance. On balance, owners appreciate the Fortis Amber Orange for its striking aesthetics and impressive lume.
