Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the CWC (Cabot Watch Company) Arctic Radar Automatic Diver Watch for its robust build, comparing its toughness to that of the Marathon GSAR, and appreciate its preferred aesthetic and smooth bezel action. One owner reports accuracy of +3 seconds per day. Some owners note fixed springbars as a potential drawback. On balance, owners rate the CWC (Cabot Watch Company) Arctic Radar Automatic Diver Watch highly for its cool factor and military connection, deeming it a very solid watch.
Owners widely praise the Zelos Spearfish 3 for its exceptional finishing, with razor-sharp transitions and polish that exceed expectations for its price point. The 40mm case is noted for its wearability, and the bracelet is considered superb, featuring a tool-less micro-adjustment clasp that is among the best from microbrands. Some owners also highlight the beautiful and unique dials as a significant draw. One owner found the titanium case too light, though later regretted selling it. The Zelos Spearfish 3 uses the La Joux-Perret G100 automatic movement. Overall, owners and reviewers rate the Zelos Spearfish 3 highly for its outstanding finishing and wearability at its price point.
The La Joux Perret G100 movement is a significant strength. The bracelet's refinement is a weakness. Reviewers disagreed on the dial material, with one noting a burnt orange sunburst and another mentioning meteorite.
