Moto Nylon Canvas Sport Waterproof Watch Band vs Omega X Swatch Mission To Moon Quartz: which is safer?

Where these two actually differ

• We flag Waterproof coating leaching (undisclosed chemistry), Coating degradation and microfiber shedding and Contact dermatitis or skin irritation from coating on the Motorola 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 Motorola.
• The Motorola is nylon canvas with waterproof coating (unspecified) where the Swatch is Quartz crystal, stainless steel case, resin band, which is most of the difference in these two grades.
• The gap is 45 points, wide enough that this is not a close call, and the Swatch is the one to buy.
• We are less certain about the Motorola grade, at 45% confidence against 78%, because it discloses less.
