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 Bradner Pearl Diver

The Spinnaker Bradner Pearl Diver is noted by owners as large on smaller wrists, with a 50mm lug-to-lug and 15mm height being a concern, though some find it acceptable with specific strap choices. Opinions on finishing quality vary, with one owner reporting issues like a poorly seated bezel and crooked indices. Overall, owners rate the Spinnaker Bradner Pearl Diver with mixed reviews regarding its size and finishing.
