I bought this on accident, actually needing a 18mm band.  It worked perfect, however, for an old wind up model I had that wouldn't ever fit any other band.
It's not particularly fancy or soft or comfortable, but is well made and fairly sharp looking.  It came fairly rigid and hasn't broken in yet, with fairly moderate use.  The clasp is sturdy and it beats the heck out of those awful 17mm 1970's spring metal bands.
