Where these two actually differ
- We flag Polymer band composition and residual monomers and Bacterial growth in sealed band-case junction on the Amazfit and not on the Nomad.
- We flag Elastomer degradation and particle shedding and Mold or bacterial growth in strap crevices on the Nomad and not on the Amazfit.
- The Amazfit is Titanium alloy case, polymer band where the Nomad is Elastomer strap, 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 →
