Notes

Diablotine The feature known as a diablotine is a small subsidiary dial on a chronograph or independent center-seconds pocket watch, the hand of which moves in a jumping fashion at intervals of 1/4 or 1/5th of a second. The term literally means ?little devil?. The diablotine is halted when the chronograph or centre seconds is stopped and the fractions of a seconds can be read.
