Where these two actually differ
- We flag Band material variability and Skin sensitization from sweat pooling on the Even Realities and not on the Citizen.
- We flag Nickel release (from stainless steel alloy), Corrosion and metal oxidation and Alloy composition variability and undisclosed materials on the Citizen and not on the Even Realities.
- The Even Realities is titanium, stainless steel, sapphire crystal where the Citizen is Stainless steel, no coating disclosed, 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, which covers 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 →
