What distinguishes it
Look beyond the reference.
The column wheel controls switching; the clutch connects the timing mechanism. These are separate parts with separate jobs, even though they often appear together in descriptions.
For the enthusiast
Chronograph architecture is more informative than the number of subdials. Compare this automatic design with the hand-wound ST1901 and Lange L951.6.
