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.

Longines LEGEND DIVER 42

Owners widely praise the Longines Legend Diver 42 for its appealing retro skin-diver aesthetic, excellent legibility, and functional inner bezel, with reviewers noting its strong value proposition below $2,500 and capability in shallow dives. Some owners find the blue dial pops in the sun and appreciate the quickset date. However, several owners report disappointment after seeing the watch in person, finding it underwhelming and lacking dial depth. Specific criticisms include original leather straps peeling easily, a clasp that scratches readily, dust getting on the dial, and lume that is not particularly strong or matching vintage charm. The 50mm lug-to-lug length is noted as potentially overwhelming for smaller wrists, and one owner experienced the minute hand scratching the hour hand. Accuracy figures are not consistently reported across sources.
