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 Withings.
- We flag Silicone band degradation and skin irritation and Battery leakage (internal lithium-ion cell) on the Withings and not on the TomTom.
- The TomTom is On watch case and band where the Withings is Stainless steel case, plastic/silicone band, electronic components, 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.
- We are less certain about the TomTom grade, at 35% confidence against 72%, because it discloses less.
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 →
