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 manner at intervals of 1/4th or 1/5th of a second. The term literally means ‘little devil’. The diablotine is halted when the chronograph or center seconds is stopped and the fractions of a second can be read.
