Marathon Steel Navigator SSNAV-D AutovsTissot PR 100

The Marathon Steel Navigator SSNAV-D Auto is praised for its durable construction, featuring a sandblasted steel case with improved lugs, a bi-directional bezel with excellent action, and 100m water resistance. Owners appreciate the constant visibility provided by self-illuminating tritium gas tubes and the precision of its ETA F06.412 quartz movement, which offers accuracy to about 10 seconds per year. 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 Tissot PR 100 for its exceptional value, with many noting its sapphire crystal, robust build, and attractive design. The Powermatic 80 variants are particularly lauded for their 80-hour power reserve and accuracy, with some reporting deviations as low as +/- 1-2 seconds per day. Owners appreciate the clean dials and practical clasps, finding the 39mm and 40mm sizes versatile. However, some owners report the crystal easily picks up fingerprints, and the stainless steel case and bracelet can show scratches or wear over time, with one instance of a bracelet falling apart after five years. Some also note that only the hands have lume, and the seconds hand may not perfectly align with markers on certain quartz models. Overall, owners rate the Tissot PR 100 highly for its impressive value and solid construction, making it a well-regarded entry-level Swiss timepiece.
