Omega X Swatch Mission To Moon Quartz vs Smartwatch Withings Scanwatch Wristband Withings ScanWatch 38mm Black: which is safer?

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 Colorants and dyes in elastomer, Rubber accelerators and vulcanization residues, Bacterial growth and biofilm and Polymer degradation and microparticle shedding on the Withings and not on the Swatch.
• The Swatch is Quartz crystal, stainless steel case, resin band where the Withings is Rubber/elastomer wristband, 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 45% confidence against 78%, because it discloses less.
