Reviews

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

Halios Seaforth IV

Owners widely praise the Halios Seaforth IV's wearability on smaller wrists, citing its manageable 40mm case and 47mm lug-to-lug distance. Admiration is frequently directed towards the sunburst blue dial and the well-executed lume on the sapphire bezel. Some owners find the steel bracelet bland on stainless steel variants, and a few express a desire for white dials or larger case sizes. One owner notes the sapphire bezel is flat and taller than preferred. On balance, owners rate the Halios Seaforth IV highly for its accessible size and quality finishing at its price point.

From video reviewers

The sunburst blue dial is a standout feature. Limited water resistance is a shared concern.

Squale Super-Squale

Owners widely praise the Squale Super-Squale for its comfortable 38mm case, vintage skin diver aesthetic, and outstanding build quality for the price, with many highlighting the beads-of-rice bracelet as a standout feature and finding it a great value "go anywhere, do anything" watch. Some owners note the stock strap is not ideal and consider alternative strap options, while one enthusiast finds the 38mm case with 18mm lug width wears small. Accuracy of the Sellita SW200-1 movement is reported as ±7–20 seconds per day, which is considered not impressive by today's standards, though adequate for reliability and serviceability. Overall, owners rate the Squale Super-Squale highly for its vintage charm, comfortable wearability, and excellent value.
