Reviews

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

Synchron Ti300M Poseidon Deep Black

The Synchron Ti300M Poseidon Deep Black is praised for its wearability, attributed to its lightweight titanium construction and a 11.9mm case thickness, making it comfortable even under a cuff. Reviewers note its retro aesthetic and good legibility with a glossy black dial. Owners and reviewers find the La Joux-Perret G100 movement to be a high-grade caliber. The watch is considered a good value, with some sources citing a price around $990-$999. On balance, owners and reviewers rate the Synchron Ti300M Poseidon Deep Black highly for its comfortable titanium build and attractive vintage-inspired design at its price point.

Zelos Spearfish 3

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.

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.
