What people say

Owners + reviewers, side by side

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

Citizen Promaster Dive E365

The Citizen Promaster Dive E365 is lauded for its wearable 46mm lugless case, a striking red gradient dial, and the Cal.E365 Eco-Drive movement with a 365-day power reserve. Owners report comfortable wearability despite its dimensions and weight, with accuracy noted as within one second of an atomic clock. Some find the red dial to appear more brownish than red, and opinions are split on the lume, with one owner finding it underwhelming compared to other Citizen divers while another states their 300m Citizen divers function as "nightlights." The watch's 16.3mm thickness contributes to an industrial feel, and the accordion-style rubber strap may be visually divisive. On balance, owners and reviewers rate the Citizen Promaster Dive E365 highly for its impressive power reserve and comfortable wearability in a robust dive watch package.

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.
