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 Divers Issue Quartz Watch Mk.2 Day/Date

The CWC SBS Divers Issue Quartz Watch Mk.2 Day/Date is widely praised for its exceptional legibility, particularly its dial design and thickly applied Super-LumiNova that remains readable all night. Owners appreciate its robust, toolish, bombproof design and comfortable wearability, with one noting its 11mm thickness and smaller wear size. The PVD finish withstands significant abuse. The Ronda movement is considered to have consistent second-hand movement. Some find its £700 price steep, especially compared to less expensive quartz divers, and fixed spring bars are noted as a drawback. Customer service is also flagged as potentially lacking by some. Overall, owners and reviewers rate the CWC SBS Divers Issue Quartz Watch Mk.2 Day/Date highly for its military aesthetics, legibility, and robust, comfortable tool-watch build.
