JAEGER-LeCOULtRE
dUOMEtRE A CHRONOGRAPHE – REF. 601.24.20
The Duomètre à Chronographe is a true masterpiece of micromechanics, supplied with two independent power reserves by its
“Dual-Wing” caliber. One power reserve is devoted entirely to the chronograph functions: hours, minutes, seconds, a display of
units per minute and a foudroyante seconds display with zero reset. A counter at 6:00 displays the jumping seconds, divided
into six units and linked to the chronograph seconds hand. The attention to aesthetic detail extends to the decoration on the
Jaeger-LeCoultre 380 caliber, as bridges that relate to conventional time measurement are finished differently from those involved
with the chronograph functions.
