The Aquastar Fratello × Aquastar Deepstar II Limited Edition is widely praised for its wearable 36.75mm case size, offering excellent comfort and wrist presence, particularly with its ice-blue or pink salmon sunburst dials. Reviewers highlight the watch's fantastic finishing and approachable price point, with the Sellita SW290-1 automatic movement featuring a sub-seconds display. Some owners find the NATO strap less ideal, and one owner expressed a desire for a larger case size and different subdial colors, while another questioned its strap versatility. Overall, owners and reviewers rate the Aquastar Fratello × Aquastar Deepstar II Limited Edition highly for its charming vintage aesthetic and comfortable wearability at its price.

Owners widely praise the Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition for its beautiful design and refinement over prior models, with its glacier-inspired textured dial being a particular highlight. However, a significant portion of the community finds the €1500 RRP to be too high, suggesting a price point closer to €900-€1000, and note the use of an aluminum bezel insert. Some owners report that the 6R movement runs slow. On balance, owners rate the Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition highly for its aesthetic refinement, though the price point is a notable concern for the community.
