CWC SBS Divers Issue Quartz Mk.2 Day/DatevsMarathon TSAR (Tritium Search & Rescue) Diver's Quartz

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 which owners report remains readable all night. Its robust, toolish 41mm Monnin-style case, often noted at a comfortable 11mm or 12mm thickness, features a PVD coating that withstands significant abuse and military aesthetics that contribute to its wearability and history. Some owners find the £700 price steep for a quartz diver, and fixed spring bars are noted as a drawback. On balance, owners and reviewers rate the CWC SBS Divers Issue Quartz Watch Mk.2 Day/Date highly for its bullet-proof, great-looking design and exceptional legibility.

Marathon TSAR (Tritium Search & Rescue) Diver's Quartz owners widely praise its high quality, extreme legibility, and bright tritium tubes that glow without needing to charge.

Some owners mention the 41mm TSAR wears small and has a field watch aesthetic, while others note the crown can dig into the wrist. The tritium tubes in the hands provide excellent brightness in the dark. On balance, owners rate the Marathon TSAR (Tritium Search & Rescue) Diver's Quartz highly for its exceptional tritium lume and robust, legible design.
