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.

RZE Fortitude GMT

The RZE Fortitude GMT is widely praised for its lightweight titanium construction and durable UltraHex coating, offering exceptional value under $700. Owners and reviewers highlight its comfortable wearability, with a bracelet featuring a quick-adjust clasp and multiple micro-adjustment positions. The Miyota 9075 flyer GMT movement is noted for its accuracy, with one owner reporting -1 to +1 seconds per day, though another source states a range of -10/+30 seconds per day. The watch's design is appreciated for its soul and attention to detail, including a subtle red crown tube indicator and faceted lugs, and its Nimbus Grey dial features a coarse, sandpaper-like texture and fumé effect. A reviewer points out the rotor can be loud and a smaller screwdriver is needed for sizing, while an owner found the GMT hand lume confusing. Overall, owners and reviewers rate the RZE Fortitude GMT highly for its comfortable titanium build, durable coating, and excellent value.
