From video reviewers

The watch's robustness and ability to withstand extreme conditions without compromising accuracy are notable strengths. The relatively high price point is a shared weakness. Reviewers disagree on the watch's thickness, with one reviewer considering it a drawback and the other not mentioning it.

Marathon Steel Navigator SSNAV Auto
