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.

Yema Skin Diver CMM.20

Owners and reviewers widely praise the Yema Skin Diver CMM.20 for its vintage aesthetic, 39mm-39.5mm case size, and the in-house CMM.20 micro-rotor movement. The watch features a textured cream dial, sharp applied indices, and a satisfyingly over-engineered push-to-turn bi-directional bezel. The fully brushed bracelet with toolless micro-adjust clasp is highlighted as a significant improvement, though some note its extended lug-to-lug may challenge smaller wrists. Accuracy figures range from -3/+7 seconds per day to erratic results between 0 and -10 seconds per day, with a 70-hour power reserve. Some owners express concerns about the brand's QC reputation and the micro-rotor movement's performance, while one reviewer noted questionable finishing on a prototype's hour hand and a rattly clasp. Overall, owners and reviewers rate the Yema Skin Diver CMM.20 highly for its vintage styling and improved bracelet at the price.

From video reviewers

The sapphire bezel insert and in-house CMM.20 movement are noted strengths. Reviewers questioned the value proposition compared to other Yema models.
