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 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.

Seiko Prospex Sea PADI Special Edition

The Seiko Prospex Sea PADI Special Edition is widely praised for its attractive, jewel-toned teal or emerald green dials with wave patterns and vibrant PADI color schemes. Owners and reviewers note its solid build quality, refined case, and good value, with some highlighting the laser-engraved bezel numerals and LumiBrite for legibility. The 6R55 movement offers a 72-hour power reserve, while the 6R15 provides 50 hours. Accuracy figures vary, with the 6R55 rated +25/-15 seconds per day and the 6R15 around +/- 15-25 seconds per day. Some find the lug-to-lug measurement, around 49.5mm, potentially long for smaller wrists, and one owner noted a unique case design made the watch wear top-heavy. Another owner found the finishing and bracelet design basic. Overall, owners and reviewers appreciate the Seiko Prospex Sea PADI Special Edition for its striking dial aesthetics and solid dive watch construction at its price point.
