Where these two actually differ
- We flag Polymer case and band degradation and Bacterial or mold growth in seals and band on the TomTom and not on the Xiaomi.
- We flag Plastic degradation and microplastic shedding, Battery leakage and electrolyte exposure, Adhesive outgassing or skin contact irritation and Nickel or cobalt allergy from stainless steel band on the Xiaomi and not on the TomTom.
- The TomTom is On watch case and band where the Xiaomi is Plastic case, glass display, stainless steel 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 →
