I carried this wallet for at least 10 years, until I received a Bosca leather wallet as a gift.  The Bosca, while comparable in cost, could not touch the durability of Coach's water buffalo wallet.  In fact, I resumed carrying the old Coach wallet after the newer Bosca wore out!

As the other reviewer noted, this wallet develops a lovely patina and an appealing time-worn look as the years pass.  The wallet is expensive up-front, but lasts many years longer than others.
