The watch includes a GMT bezel for dual timekeeping and a synthetic sapphire crystal. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV-D Auto highly for its robust tool-watch design and reliable tritium illumination.

Owners widely praise the Zelos Blacktip 200m Ti for its value, titanium construction, and unique dial options, with many appreciating its comfortable 41mm size and angled lugs.
