What people say

Owners + reviewers, side by side

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

CWC Automatic Divers Watch Mk.2 Black

Owners widely praise the CWC Automatic Divers Watch Mk.2 Black for its brushed chapter ring, precise 120-click bezel, clear sapphire crystal, excellent case finishing, and significantly improved lume. The watch is considered a terrific value with solid construction. Some owners express a preference for a matte finish for a more tool-like appearance, though polished versions offer a dressier look and easier scratch removal. On balance, owners rate the CWC Automatic Divers Watch Mk.2 Black highly for its tool-like features and excellent value.

From video reviewers

The bezel action is smooth. The price has increased due to popularity.

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.
