Reviews

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

CWC 1980 RN Divers Automatic Re-Issue Watch

Owners widely praise the CWC 1980 RN Divers Automatic Re-Issue Watch for its faithful recreation of military aesthetics and historical dial markings, with many finding its 41mm size and wearability excellent. The fixed spring bars are a liked feature for some, enabling secure NATO strap wear. However, criticism is directed at the "faux patina" lume, which some find too gold, glossy, or mismatched between hands and hour markers, with the hour markers' lume described as overly shiny and convex. Some owners also flag the steep pricing and fixed bars as drawbacks for those not preferring NATO straps. Overall, owners and reviewers rate the CWC 1980 RN Divers Automatic Re-Issue Watch highly for its authentic vintage military design and comfortable wearability.

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 1968 Heritage Diver's GMT

The Seiko Prospex Sea 1968 Heritage Diver's GMT is widely praised for its build quality, finishing, and value, with owners noting its comfortable wearability and attractive aesthetic, particularly the silver/white sunray dial and blue ceramic bezel. The improved bracelet clasp with excellent micro-adjustment is a recurring positive point. Some owners report accuracy figures of +3 seconds per day or +/- 5 seconds per day, exceeding the movement's stated range. However, the GMT functionality is considered secondary to its dive watch capabilities by some, with the GMT scale being difficult to read and the caller-style GMT movement being a drawback for certain users. The dial contrast is also noted as lacking by some, and the crown at 4 o'clock is undesirable for a few. On balance, owners and reviewers rate the Seiko Prospex Sea 1968 Heritage Diver's GMT highly for its blend of dive watch character and GMT functionality, offering significant features for its price.
