Hello Noah, it is a natural hide and it is strong but is leather so the use will change it slowly in time. When I was working in the boutique a client was bying watches and put exactly with the box in the safe , not for resell just to collect. that watches will never change .. but frankly I prefer to use my watches
that time In Portofino I had not yest started my straps.. so I was using the OEM velcro.
now as a Gradma a lot of swimming pool and not much diving
