What people say

Owners + reviewers, side by side

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

CWC SBS Black Ice Quartz Watch

Owners widely praise the CWC SBS Black Ice Quartz Watch for its legible, uncluttered dial, excellent Super-LumiNova lume, and robust build quality, noting its comfortable 12mm thickness and durable PVD coating. The bezel action is described as having zero back play, and the fixed lugs are appreciated for easy strap changes. One owner reported the lume is readable throughout the night, while another flagged a faulty mechanism requiring replacement and poor retailer customer service. The £700 price is considered high by some compared to similar quartz divers, leading to questions about its value. Overall, owners rate the CWC SBS Black Ice Quartz Watch highly for its bombproof, toolish design and practical aesthetics.

Grand Seiko SLGC006

Owners widely praise the Grand Seiko SLGC006's stunning copper Mount Iwate dial and its high-frequency Caliber 9SC5 movement, which operates at 36,000vph and achieves accuracy between -3/+5 seconds per day with a 72-hour power reserve. Reviewers note the watch's large 43.2mm size, though some find the Evolution 9 case design improves wearability. Criticisms include the $22,600 price point, the 4:30 date window placement, and the lack of bracelet micro-adjustment. Opinions on the dial are split, with some finding it beautiful and others comparing it to rust or the Australian outback. Some question the extent of the gold accents for a "two-tone" designation. Overall, owners and reviewers acknowledge the Grand Seiko SLGC006's striking aesthetics and advanced movement, but debate its value proposition and certain design choices.
