Where these two actually differ
- We flag TPU degradation and surface deterioration and Waterproof seal integrity and bacterial growth on the Samsung 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 Samsung.
- The Samsung is TPU 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.
