What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

CWC 1980 RN Divers Automatic Re-Issue Watch

The CWC 1980 RN Divers Automatic Re-Issue Watch is widely praised for its faithful recreation of vintage details, including its dial layout with markers touching the chapter ring and pointed crown guards. Owners and reviewers note its reasonable size and the original minute hand design. However, the lume is a point of contention: some find the "faux patina" tint too gold and glossy, while others specifically criticize the mismatched lume color between hands and hour markers, with the hour marker lume described as overly shiny and convex. On balance, the CWC 1980 RN Divers Automatic Re-Issue Watch is highly regarded for its authentic vintage aesthetic and wearability, despite mixed opinions on the lume application.

From video reviewers

The watch's accurate movement is a notable strength. A potential weakness is its relatively high price point. Reviewers disagree on the watch's water-resistance, with one reviewer suggesting it could be improved and the other not mentioning any issues with water-resistance.

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.
