What people say

Owners + reviewers, side by side

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

Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition

The Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition is praised for its beautiful design and refinement over previous models, featuring vertically textured glacier-inspired dials. Owners, however, consider the €1500 RRP too high, suggesting a price closer to €900-€1000, noting the aluminum bezel insert instead of ceramic. Some owners report the 6R movement runs slow. On balance, owners find the Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition beautiful and a refinement, but the price and aluminum bezel are points of contention.

Zelos Thresher 44

Owners widely praise the Zelos Thresher 44, with one owner noting its finish has proven remarkably scratch-resistant. However, one owner found the finishing on their hammered grey variant not as well done as expected. The Zelos Thresher 44 with an agate dial sold out in 90 seconds, with one owner receiving theirs and noting the bracelet was fully wrapped. Overall, owners rate the Zelos Thresher 44 highly for its desirability and scratch-resistant finish.
