Partially verifiedA chronograph capable of measuring and displaying intervals as small as one-hundredth of a second.
Definition
A chronograph capable of measuring and displaying intervals as small as one-hundredth of a second.
Historical origin
Pushes the limits of mechanical frequency and energy management.
How it works
Usually requires a very high-frequency escapement (360,000 vph) or a secondary high-speed train for the chronograph.
The central hand often rotates once per second.
Pocket watch context
None.
Wristwatch context
Produced by Zenith (El Primero 21) and TAG Heuer.
Identification
- A central hand that spins at a blurring speed (1 rps)
- Scale graduated to 100
Servicing notes
Extremely high energy consumption; usually has a very short power reserve for the chronograph train.
General guidance only. Complicated mechanisms should be assessed and serviced by a qualified watchmaker or clockmaker specialist, not adjusted at home.
