6 Fitness Tracker vs Omega X Swatch Mission To Moon Quartz: which is safer?

Where these two actually differ

• We flag Silicone band skin irritation or allergic contact dermatitis, Azo dyes or colorant migration in silicone band, Metal components (buckle, casing hardware) nickel or cadmium content and Volatile organic compounds (VOC) off-gassing from polymer housing on the Realme and not on the Swatch.
• 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 Realme.
• The Realme is Silicone band, plastic/polymer components where the Swatch is Quartz crystal, stainless steel case, resin band, 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 Realme grade, at 45% confidence against 78%, because it discloses less.
