Introduction
Duomètre à Sphérotourbillon
Over the past decade, the Manufacture Jaeger-LeCoultre, building
on a longstanding tradition of inventiveness and unique expertise,
has displayed exceptional creativity, achieving technical performan-
ces that have enabled it to develop some of the most noteworthy
complications of the early 21
st
century.
Armed with exceptional horological know-how, Jaeger-LeCoultre
gladly starts with a blank page for each new creation in order to
combine aesthetic elegance, technical performance and unique
functions.
Today, the Grande Maison in the Vallée de Joux is propelling
watchmaking firmly into the third millennium. The Duomètre
à Sphérotourbillon unites peerless technical performance, ele-
gance and a spectacular complication.
Le Sphérotourbillon :
A precision-adjusted tourbillon
Precision is the cornerstone of the Dual-Wing concept and was
the watchword for the Jaeger-LeCoultre watchmakers in their
reflection leading to the creation of the Duomètre à Sphéro-
tourbillon. The result is a watch that can legitimately claim to be
the first tourbillon watch adjustable to the nearest second. For
what’s the point of precision if you can’t display it?
There are indeed very few tourbillon models with an extre-
mely readable display of the seconds in a dedicated subdial,
and even fewer with a stop seconds device. Certainly none
until now had ever enabled the user to stop the seconds hand
and bring it back to zero in order to perform an ultra-accurate
time setting.
Using the Dual-Wing concept enabled the Jaeger-LeCoultre
watchmakers to create the first precision-adjusted tourbillon.
A push-piece at 2 o’clock serves to bring the small seconds
hand positioned beneath the tourbillon back to zero, accor-
ding to the flyback principle.
