The leather straps at Alava are made of Italian Calf leather, with a vegetable tanned lining, and it's always good to take care of your leather.
When putting on and removing your watch, try not to give the strap any unnecessary pulling or bending. All leather stretch, and pulling it too hard will eventually cause the strap to stretch. Try also not to bend the long part of the strap too much, when inserting the buckle tang into the buckle hole. This will cause the strap unnecessary creasing.
Our leather straps have been conditioned, so you don't need to add any conditioner in a long time.
When cleaning the strap from sweat, grease or dirt, dip a cloth or another soft fabric into warm water and gently wipe the leather clean. Next, take a tiny bit of leather conditioner and rub it between your fingers, then gently rub it in to the strap. Try to avoid getting too much of the conditioner on the stitching, as it might be hard to remove.
When you're done. Let it sit and absorb for few minutes. Lastly, gently wipe off any remaining conditioner with a soft cloth.
Now your strap has a beautiful, shiny new coat. Easy.
