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.

LONGINES SPIRIT ZULU TIME

Owners widely praise the Longines Spirit Zulu Time for its superb finishing, smooth crown action, and mesmerizing ceramic bezel, with many noting its premium pilot/sporty design and unique dial details. The movement is consistently lauded for its extreme accuracy, running at 0 to +1 second per day, and the watch is considered to offer remarkable value that punches above its price point. However, the bracelet is criticized by multiple sources for its push-pin adjustment and limited micro-adjustment holes, and the 42mm case size with a 49.3mm lug-to-lug is noted as potentially large for smaller wrists, though some users express a preference for the 39mm size. One owner reported their movement failed within the first year and found setting the date a "nightmare," while another owner notes minor criticisms like the date window being slightly off-center. On balance, owners and reviewers rate the Longines Spirit Zulu Time highly for its impressive finishing and accuracy at its price point.

From video reviewers

The 39mm case size is a significant strength, addressing previous concerns about thickness. The value proposition within the GMT market is also a shared positive point. No consensus on weaknesses was reached.
