Instructions

•   Pull the crown out to the 1st click position.

•   Pull the crown out to the 2nd click position when 

the second hand is at the 12 o'clock position.

•  Turn the crown to set the hour and minute hands.
•  Turn the crown clockwise to advance the hour and 

minute hands past 12:00 midnight. This will advance 
the date to the current date.

•  Take  AM/PM  into  consideration  when  setting  the 

hour and minute hands to the desired time.

•   Push the crown back to the normal position. 

Recommend:

•  The hands should be set to the time a few minutes ahead of the 

current time, taking into consideration the time required to  
adjust the stopwatch hand position if necessary.

•  When setting the minute hand, first advance it 4 to 5 minutes 

ahead of the desired time and then turn it back to the exact 
minute(s).
