Where these two actually differ
- We flag Fluoroelastomer seal composition (PFAS undisclosed), Elastomer degradation over time and Nickel or other trace metals in titanium alloy on the Apple 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 Apple.
- The Apple is Titanium case, fluoroelastomer seals, composite band where the TomTom is On watch case and band, 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 →
