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.

Tissot Gentleman Open Heart

Owners widely praise the Tissot Gentleman Open Heart for its versatile dressy-sporty aesthetic and elegant sunburst dial finish, with one owner preferring its less shiny blue dial compared to other versions. The watch offers excellent fit and bracelet adjustability, and its modified Powermatic 80 movement achieves COSC-level accuracy of -3 to +5 seconds/day, though the seconds hand movement is slightly less smooth at 6 movements per second. However, one owner reported the watch arrived non-functional, requiring a return due to an inoperable movement. On balance, owners rate the Tissot Gentleman Open Heart highly for its aesthetic appeal and accurate timekeeping, despite a reported instance of a faulty movement.
