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 Skyraider 40 Skeleton

The Zelos Skyraider 40 Skeleton is noted for its skeletonized dial and the use of BGW9 and C3 Super-LumiNova for legibility. It is powered by a manual-wind ETA 6498 movement, offering a 44-hour power reserve. On balance, the Zelos Skyraider 40 Skeleton is seen as a cool-looking option, though availability is a factor.
