To set the alarm, first select the date, referring to the diary alarm window positioned within the subdial at 10 o’clock. Press the pusher positioned at 8 o’clock until the letter ‘d’ appears in the window. Turn the 10 o’clock crown until the red and silver pointer selects the correct date from Arabic numerals 1 to 31.
To set the time, press the pusher once more; the letter ‘h’ appears. Turn the crown to select the time, referring to the aperature at 6 o’clock, from quarter-hour intervals from 00.15 to 24.00 hours. To set the alarm, press the pusher once more to bring the alarm symbol (a bell) into view, then turn the crown to wind the alarm. When the set date and time arrives, the alarm rings – for up to one minute.
To stop the alarm (or to cancel one set previously), press the 8 o’clock pusher until the ‘alarm off’ symbol appears in the window (a black line struck through the bell).
