One Hertz

The One Hertz Ruthenium indicates hours and minutes on a sub-dial at 2 o’clock and has a large subdial for the dead seconds at 7 o’clock; the innovative setting-winding indicator at 3 o’clock is counter-balanced by the power reserve indicator, placed at 12 o’clock on the hour-minute sub-dial – the classic One Hertz position for this complication.
