Movement

Jaeger-LeCoultre Calibre 382

Important remark regarding the power reserves of the

Calibre 382 Dual-Wing of the Duomètre à Sphérotourbillon

watch model.

The Dual-Wing movement of the Duomètre à Chronographe

watch model comprises two barrels. The first barrel provides

the watch's regulator (regulating organ) with 45 hours of power

reserve. The second barrel, which is independent from the first,

provides all the watch's functions with 45 hours of power reserve.

The power reserve of the regulator is read off by means of

the blue hand situated at 1 o'clock and marked "regulator". The

power reserve of the regulator is read off by means of the hand

situated at 5 o'clock and marked "hour".

In both cases, the power reserve is at its maximum when

the hand is positioned opposite the "+" symbol. As energy is

consumed, the hand will gradually point towards the "-" sym-

bol. When the hand is opposite the "-" symbol (after approx-

imately 45 hours for both the escapement and the functions), this

indicates that the power reserve has been exhausted. This is the

last chance to wind up the watch without losing the settings.

Both barrels can be wound using crown A, in position 1.

Turning the crown counter-clockwise winds the regulator bar-

rel, thereby increasing its power reserve.

Turning the crown clockwise winds the functions barrel, thereby

increasing its power reserve.

Important:

Although the two power reserves are independent, it is vital

that both are wound before the timepiece can be used.

If one of the power reserves is depleted, the movement will

stop (no damage will be caused to the movement). It will thus

be necessary to wind the two power reserves according to the

instructions to restart the calibre.
