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.

Grand Seiko SLGA001

The Grand Seiko SLGA001 is praised for its impressive technical achievements, including a new, slimmer Spring Drive movement with a five-day power reserve and exceptional accuracy of ±0.5 seconds per day. Reviewers note the 47mm titanium case, despite its substantial dimensions, wears more comfortably due to its titanium construction, short lugs, and virtually scratch-proof finish. The watch features a 600-meter water resistance and is limited to 700 pieces, priced at $11,100. On balance, reviewers consider the Grand Seiko SLGA001 a highly capable dive watch, with its technological advancements in the Spring Drive movement being a key highlight.

From video reviewers

The watch's Spring Drive movement, specifically the Cal.9RA5, offers a 120-hour power reserve. A notable trade-off is the watch's relatively large size, with a case diameter of 46.9mm and thickness of 16.0mm, which may not suit those with smaller wrists. The high price point may be a trade-off for some buyers.
