Where these two actually differ
- We flag Water-repellent coating (likely PFAS source) and Synthetic strap material degradation on the Moto and not on the TomTom.
- We flag Polymer case and band degradation and Bacterial or mold growth in seals and band on the TomTom and not on the Moto.
- The Moto is Unspecified composite case, likely stainless steel back, synthetic strap where the TomTom is On watch case and band, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
