Reviews

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

Spinnaker Fleuss 40 Automatic

The Spinnaker Fleuss 40 Automatic is noted as a good size for smaller wrists, with one owner finding it comfortable on a 6.25-inch wrist. However, the lume is considered too diffuse for easy nighttime reading of the hands. The pilot-style crown is an unusual design choice for a dive watch. Overall, owners and reviewers find the Spinnaker Fleuss 40 Automatic to be a well-sized and comfortable watch with a unique crown design.

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.

From video reviewers

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.
