Water Resistant Watch Model 8R500 - Men vs ,white Field Band Nylon Wristband 42mm Apple Watch: which is safer?

Where these two actually differ

• We flag Polymer case and band degradation and Bacterial or mold growth in seals and band on the TomTom and not on the X-Doria.
• We flag Azo dyes and colorant migration, Formaldehyde resin finishes and Mold and bacterial growth on the X-Doria and not on the TomTom.
• The TomTom is On watch case and band where the X-Doria is Nylon 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 TomTom grade, at 35% confidence against 72%, because it discloses less.
