Using The Chronograph - iwc INGENIEUR PERPETUAL CALENDAR DIGITAL DATE-MONTH Operating Instructions Manual

READING THE CHRONOGRAPH
Chronograph seconds hand: The scale for the central
chronograph seconds hand runs around the edge of the dial.
Minute and hour counters: The subdial at 12 o'clock has two
hands, which run continuously and show the elapsed time
on a 12­hour and a 60­minute scale. The hour and minute
counters can be read like a standard analogue time display.
In other words, one revolution of the minute counter is equal
to 60 minutes, and one revolution of the hour counter is equal
to 12 hours.
