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.

Yema Yachtingraff Seconde/Seconde/

The Yema Yachtingraff Seconde/Seconde/ is a collaboration watch featuring a hand-painted graffiti-style dial with wet paint drips and spray can pushers, powered by a Seiko VK63 meca-quartz movement. One owner noted slight marks on the lugs, bezel, and case of a pre-owned example, rating its condition at 88%. On balance, reviewers highlight the artistic and humorous blend of design elements as the watch's primary appeal.
