A watch band is much like a good pair of shoes: some last a season and others of better quality that seems eternal. And the same goes for watch bands; some are made sloppily or with poor quality leather and, after two years, are thrown away. Others, however, last a lifetime.
Good maintenance of a strap, however, helps to prolong its life. And this is very important, mainly because original straps, if adequately maintained, add value to a watch. So much so that many collectors, once they purchase the watch, replace the wristband with a generic model and keep the original strap disassembled to maintain its value.
