Chronograph seconds hand: The scale for the central chrono-
graph 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
12-hour and a 60-minute 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.
