Owners widely praise the Islander Hudson "Harpoon Diver" 40mm Watch with Degrading Black Dial #ISL-302 for its eye-catching degrading black dial and strong lume. Some owners note the bracelet's tight links and rough clasp edges as drawbacks, though one owner received a replacement bracelet that improved wearability.

On balance, owners appreciate the Islander Hudson "Harpoon Diver" 40mm Watch with Degrading Black Dial #ISL-302 for its unique dial and value, despite some reservations about the bracelet finishing.

Zelos Helica

Owners widely praise the Zelos Helica for its stunning, often color-shifting dials, with specific mentions of the MoP, slate grey, 'Steel Blue', and red opal variants being particularly captivating and artful. The 39mm case size is noted as fitting well on smaller wrists, and the overall build quality and finishing for the price are frequently highlighted as impressive, with one owner calling it "a lot of watch for the price." Some owners appreciate the novel bracelet designs and full lume dials, while others find the bracelet and clasp edges sharp or the clasp lacking on-the-fly adjustment. Opinions on the date window are mixed, with one owner disliking it. The Zelos Helica Moonphase was considered cluttered by one owner, and its $1K USD price point was felt to be steep by another, though popular variants sold out rapidly. Overall, owners rate the Zelos Helica highly for its striking dial designs and impressive value proposition.
