A glance during the session
A glance at your wrist is enough to follow the session without handling your iPhone.

Useful in a car, on a motorcycle and in a kart
On a motorcycle or in a kart, pulling out the phone is not an option. On the wrist, the timer stays readable.
In a car, the watch complements CarPlay and the iPhone. You choose where you look. The session is the same.
Car
Track days and club outings.
Motorcycle
A glance, without letting go of the bars.
Kart
The same timer, on a shorter lap.
The phone keeps timing
The iPhone detects laps, including while it is locked. The watch shows the timer. It does not replace the analysis.
Sectors, braking, speed, the theoretical lap, history and leaderboards stay in ST1 Track after the session.
