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.

Seiko Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition

The Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition features a 40mm case, 300m water resistance, and a 72-hour power reserve from the Calibre 6R55 movement, with a new grey bezel insert and a wave-patterned silvery-white dial. Owners find the watch attractive and the large case wears well without feeling bulky. However, some consider the price of €1900 for a 6R54 movement with an accuracy of +25/-15 seconds per day to be too high, and the production run of 6000 units is not seen as a true limited edition. Overall, owners find the Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition aesthetically pleasing with good wearability, but express concerns regarding its value proposition and movement accuracy for the price.
