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.

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.
