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 .
- We flag Stainless steel nickel content and skin sensitization, Seal degradation and bacterial/fungal growth in water exposure and Battery leakage or chemical exposure from internal power cell on the and not on the Amazfit.
- The Amazfit is Titanium alloy case, polymer band where the is Stainless steel body, 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 →
