Where these two actually differ
- We flag Resin band VOC off-gassing, Resin band degradation over time and Nickel leaching from stainless steel case on the Swatch and not on the Withings.
- We flag DWR (durable water repellent) treatment chemistry, Skin sensitization from band contact and Coating degradation and microparticle release on the Withings and not on the Swatch.
- The Swatch is Quartz crystal, stainless steel case, resin band where the Withings is Stainless steel case, sapphire crystal, elastomer bands with water resistance, 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.
- We are less certain about the Withings grade, at 35% confidence against 78%, because it discloses less.
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 →
