As leather is a naturally porous material, you should prevent the leather strap from coming into contact with oily substances, solvents, detergents or cosmetics. By doing this you will be able to help prevent the discoloration or premature ageing of the material.

To clean your leather strap, follow these steps: 

  1. Remove the strap from your watch and use a dry microfiber cloth to wipe off both sides. Doing this will ensure any trapped dirt will not scratch the leather. 
  2. Next, dampen — do not soak — a microfiber cloth and apply a tiny drop of mild hand soap or saddle soap to the cloth (about the size of half a dime). Do not aggressively rub the leather back and forth; instead, use tapping movements and wipe in gentle circles, applying light pressure and paying attention to spots with dirt. 
  3. With a second damp microfiber cloth, gently wipe the leather clean. Don’t use too much water, as it can cause damage to the leather. 
  4. Give the strap plenty of time to fully dry before wearing it again. 

As an option, treat the leather with your favorite leather oil or conditioner to soften and protect it. Follow the product's instructions to ensure the best care of your leather strap.
