The Marathon OSAR-D (Original SAR with Date) Automatic 46mm is widely regarded as a rugged and legible timepiece, featuring a familiar geometric dial with MaraGlo lume and a white dial with applied hour markers that enhance legibility. Owners and reviewers note its 300-meter water resistance and the reliable Swiss-made Sellita SW200-1 automatic movement with improved shock protection. The watch is described as large, thick, and heavy, with some owners finding it comfortable on the wrist while others note its substantial presence, particularly at a table. Overall, owners and reviewers appreciate the Marathon OSAR-D (Original SAR with Date) Automatic 46mm for its rugged build and excellent legibility.

Bell & Ross BR-X3 Blue Steel

The Bell & Ross BR-X3 Blue Steel is noted for its integration of the Kenissi movement into the BR-03 case, featuring a layered dial with a reoriented power reserve indicator. Owners find the lume bright, though less so in person than in images, and appreciate the comfort and unique dial variations, viewing it as an experimental piece. Reviewers note the three-date window is less clear than a single date display and find the blue dial's shininess excessive.
