CWC SBS Black Ice Quartz WatchvsNivada Grenchen Chronomaster Valjoux

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.

The Nivada Grenchen Chronomaster is praised for its vintage aesthetic and versatility, with the Aventurine Blue variant offering a unique starry dial and world time bezel. Owners note the sub-dials are small and difficult to read, and the Sellita SW510 movement exhibits rotor wobble and hand play. The $5,000 price point is a significant increase from previous reissues. Overall, owners rate the Nivada Grenchen Chronomaster highly for its vintage aesthetic and unique dial options, despite some concerns about sub-dial legibility and movement characteristics.
