Q: Hermes watch band care

Hi

For leather bands, Apple's cleaning instructions are:

• Wipe down the band with a nonabrasive and lint-free cloth.
  • If needed, you can lightly dampen the cloth with fresh water.
• Leather bands are not water resistant.
  • Soaking them might cause discoloration, skin irritation or other damage.
• Let the band air dry.
  • Direct sunlight, high temperatures, and humid conditions can cause damage.
