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.

Spinnaker Hass Automatic

The Spinnaker Hass Automatic is a 43mm watch featuring an NH35 movement and sapphire crystal, with owners highlighting its beautiful dial. Some find Spinnaker watches, including this model, to be on the thicker side, with one owner describing the Hass X MCS Blue Fade variant as comically large and chunky. The Spinnaker Hass Automatic was offered at $445 USD as part of a special collection with customized elements, and a limited edition of 200 pieces was also available for $195 shipped. On balance, owners and reviewers note the attractive dial as a key positive, though some express reservations about the watch's thickness.
