Where these two actually differ
- We flag Elastomer band degradation and microparticle shedding, Skin sensitization from band contact and Seal degradation and internal corrosion on the Misfit 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 Misfit.
- The Misfit is Stainless steel case, polymer/elastomer band 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 →
