Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Borealis Sea Storm MK2 GMT is noted for its retro aesthetic, featuring modern components, a black and white bezel, and an orange GMT hand. Owners highlight its ample lume and a well-made bracelet. The watch is described as being a relatively thick, yet surprisingly wearable, 41.5mm case size, with a date window that integrates smoothly into the dial. Overall, owners rate the Borealis Sea Storm MK2 GMT highly for its retro vibe and modern execution at its price point.
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.
