     the watch and made electrical contact.  This clip had a socket
     for a stereo style jack lead the other end of which was a
     25-way D-type connector.  The lead allowed you to enter
     phone numbers etc. into the watch without having to play with
     tiny buttons.  It also meant if the battery on your watch ran
     out you could restore the data without having to type it all
     in again.
