Received quickly.  This is identical to the watch it has replaced.  The original watch has been worn constantly for years without a problem.  We had to replace it because we must have done something to it when we replaced the battery because we couldn't get the back reattached (have replaced battery a number of times without problems).  It's still running fine so we plan to take it to a jeweler to see if he can reattach the back and tell us what we did wrong.
