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.

Zelos Spearfish 3

The Zelos Spearfish 3 is widely praised for its exceptional finishing, with razor-sharp polish and flawless brushed transitions that owners feel exceed its price point. The 40mm case is noted for its wearability, and the La Joux-Perret G100 movement offers a 68-hour power reserve, with reported accuracy averaging +2.6 seconds per day. Reviewers highlight the exceptionally smooth bi-directional bezel and a tool-less micro-adjustment clasp described as best-in-class among microbrands. The sapphire sandwich construction and lumed bezel are also cited as desirable features. Overall, owners and reviewers rate the Zelos Spearfish 3 highly for its outstanding finishing and value at its price point.
