Where these two actually differ
- We flag Skin sensitization or contact dermatitis from elastomer additives, Bacterial or fungal growth on band surface, Degradation and microparticle shedding with age or UV exposure and Allergic reaction to fragrance or dye in colored bands on the Fitbit 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 Fitbit.
- The Fitbit is Silicone or elastomer band (unspecified polymer) 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.
- We are less certain about the TomTom grade, at 35% confidence against 62%, 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 →
