These automatic chronograph models feature a
fine 25-jewel Swiss movement with 48-hour power
reserve, minute counter (up to 30), hour counter,
and small seconds subdials; center-mounted
chronograph seconds hand, and date display.
They can be used to time an event up to 12 hours,
30 minutes and 59 seconds in duration to the
nearest second.
NOTE: The motion of your arm during normal daily
activities should be sufficient to keep an automatic
timepiece wound. However, if you have not worn
your watch for more than 48 hours and it has
stopped, you will need to wind your chronograph
movement by hand before setting the time or
operating the chronograph functions:
1. With the crown in position 1, flush against the
case, turn the crown clockwise approximately
20 revolutions.
2. Reset time following instructions below.
