durable, long enough for sure (i had to cut mine down and burn the edge), and sturdy.  has a nice "thick" feel to it, the metal bands are great and hold the band in place when you fold it back over.  I took this (and my military watch) to Sears watch repair and the same watch and band in black color--both were adjusted properly for $6.  What a deal!  This strap will last.  Like I said, if you cut down the strap, be sure to burn the edge so it does not fray.  Very pleased with this
