Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Glycine Sea Kraken is widely praised for its retro design and excellent finishing for its price point. Owners highlight its crisp dial printing, elegant stainless steel bezel, and the smooth winding feel of its Sellita SW200-1 movement, with accuracy reported between +1/+2 and +6 seconds per day, though one owner noted it could lose up to 6 seconds when very active. The 39mm case size is generally considered comfortable, though some find its 48mm lug-to-lug measurement wears larger than expected. The included leather strap is frequently criticized as being of poor quality and unsuitable for a dive watch, prompting many owners to replace it. The Glycine Sea Kraken is considered an underrated watch offering great value, especially given its limited production and superior finishing compared to other Glycine models.
The Glycine Sea Kraken's value at its price point is a significant strength. Reviewers did not reach a consensus on any weaknesses.
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.
