Lot Essay
The property of an Important Private Collector, the present timepiece is offered in very good overall condition and with the full set of accessories.
Launched at SIHH (Salon International de la Haute Horlogerie) in 2013, the model was developed based on two innovations, both included in its name, the 'Duomètre' as well as the 'Sphérotourbillon'. It can be considered as one of the most charismatic and coveted watches of Jaeger-LeCoultre's modern production.
The 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 Sphérotourbillon. The result is a watch that can legitimately claim to be the first tourbillon watch adjustable to the nearest second.
There are indeed very few tourbillon models with an extremely readable display of the seconds in a dedicated subsidiary dial, 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, according to the fly back principle.
One special feature of this fly back system is that it does not halt the operation of the regulating organ. The small seconds hand is reset to zero and begins running again instantly. This means the watch maintains optimal precision even when accurately adjusting the time to the nearest second.
