What people say

Owners + reviewers, side by side

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

Islander Hudson "Harpoon Diver" 40mm Watch with Degrading Black Dial #ISL-302

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. Opinions are split on the watch's design, with some finding it overdesigned and reminiscent of older Seiko mods, while others appreciate its originality and find it appealing, particularly at its discounted price. 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.

Studio Underd0g Full Moon

Owners widely praise the Studio Underd0g Full Moon's harmonious creamy dial and its 37mm case, which fits flawlessly. The innovative sapphire disc with numerals is a highlight, though two visible screws holding it are noted as a minor aesthetic drawback. Some owners find the watch overpriced, while others see value in the upgraded Sellita movement under $1k. Lume is surprisingly good, and the included NATO strap is preferred by some over the leather. Accuracy ranges from +1/+2 seconds per day to about -6 seconds per day. On balance, owners rate the Studio Underd0g Full Moon highly for its versatile dial and well-fitting case at the price point.
