this is the second strap i have bought. the first lasted me a few years of everyday use and i am fine with that. it is leather and will wear out over time but it has outlasted a few other leather straps that came on watches from the factory so i am pleased. the leather is this and substantial and flexable and takes on a nice patina over time and wear. i am very pleased with this strap it can take a fair bit of abuse and still look good (note, it does NOT come with spring bars)
