Genghis the Engineer,
My top-notch Breitling Navitimer copy, has Seiko internals and my 'second' marker pointer jumped a digit too.
To rectify it, you pull out the crown from its stop, and manipulate the 'lower' reset button (the one that resets your stop watch - assuming the movement is the same) and this will make the pointer move to the next marker, keep pressing the button until it gets to the desired point.
Hope that helps.
PD
