Calibre 630 was a quartz watch movement with a mechanical chronograph developed by Jaeger-LeCoultre and also used by IWC.
Introduced in 1987, Calibre 630 was the first member in the Jaeger-LeCoultre Mechaquartz family. It was a complicated movement, with 25 jewels.
There are two motors in the calibre:
One powers the main timekeeping hands at a frequency of 1 Hz
A second powers the mechanical chronograph at 4 Hz
Since the chronograph is mechanical, it has the same feel as a conventional chronograph movement, including mechanical zero reset. Yet the Mechaquartz was much more compact than a conventional automatic chronograph movement.
