One of the most captivating and technically remarkable pieces of the brand's contemporary era is the Jaeger-LeCoultre Duomètre Sphérotourbillon, which was introduced at SIHH (Salon International de la Haute Horlogerie) in 2013. The 'Duomètre' concept and the 'Sphérotourbillon', two of the manufacturer's most important innovations, are combined in the model's name, which perfectly captures the spirit of its innovation. When combined, they perfectly demonstrate Jaeger-LeCoultre's unrelenting quest for elegance, intricacy, and precision.
The Sphérotourbillon: A Precision-Adjusted Tourbillon
The Dual-Wing concept, a ground-breaking idea developed by Jaeger-LeCoultre to isolate the energy sources of the watch's complications from its timekeeping functions, is centered on precision. This idea is taken to the next level in the Duomètre Sphérotourbillon, which is one of the first tourbillon wristwatches that can be adjusted 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.
The Sphérotourbillon, as opposed to conventional tourbillons, is a multi-axis mechanism that compensates for gravitational errors in all positions by rotating on two different axes: one horizontal and one inclined at 20°. Additionally, the seconds hand beneath the tourbillon can be reset to zero without stopping the regulating organ thanks to a flyback zero-reset seconds mechanism that is triggered by a pusher at two o'clock. This clever system maintains the accuracy and continuous operation of the watch while allowing the wearer to make an incredibly accurate time adjustment.
