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 PFAS in water-resistant coating and Fluoroelastomer strap degradation and leaching on the Withings and not on the TomTom.
- The TomTom is On watch case and band where the Withings is Stainless steel case, sapphire crystal, fluoroelastomer strap with water resistance coating, which is most of the difference in these two grades.
- The gap is 45 points, wide enough that this is not a close call, and the TomTom is the one to buy.
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 →
