In addition to positions for setting the time and date, an additional position is provided to change the position of the second hour hand. This may be controlled by a spring and detent mechanism so that the hour hand may occupy one of the twelve available positions, at integer numbers of hour intervals away from the main hour hand setting.</p> |
