Bremont S500vsMarathon Steel Navigator SSNAV Auto

Owners widely praise the Bremont S500's excellent Super-LumiNova lume and refined finishing, with many finding its 43mm case comfortable and versatile on the wrist due to short lugs and an offset crown. Reviewers and owners alike note its handsome, rugged design and improved dial legibility for diving. However, some find the 16mm to 16.5mm thickness less practical for daily wear, and one reviewer flags legibility issues with the dark dial and hands. Concerns are raised by one source regarding the three-piece case construction's long-term water resistance for actual diving, while another criticizes the understated bezel markings and the second hand's visibility in low light. The COSC-certified ETA 2836-2 movement provides a 38-hour power reserve. On balance, owners and reviewers rate the Bremont S500 highly for its distinctive design and robust build quality, despite some reservations about its thickness and specific legibility elements.

The Marathon Steel Navigator SSNAV Auto is praised for its high-accuracy quartz movement, with owners noting its comfort and reliable performance. Reviewers highlight its functional tool-watch appeal, featuring a sandblasted steel case, tritium tubes for constant low-light visibility, and 100-meter water resistance. One owner finds the 41mm case runs a bit small. The Marathon Steel Navigator SSNAV Auto utilizes an ETA F06.412 quartz movement with a claimed accuracy of +/- 10 seconds per year and includes a GMT bidirectional bezel. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV Auto highly for its comfortable wear and dependable, high-accuracy quartz movement.
