Sweet merciful watch gods! What is that! That’s a single hand escapement, called the Isometer by JLC. Seriously. This is a very big deal. The standard escapement loses accuracy because the little jeweled hands move back and forth, leading to friction et al. This apparently has one little hand that swings the balance wheel. More as we get it.
The Reverso Grande Complication a Triptyque is the results of tireless effort by many constructeurs and watchmakers under the strong guidance of the Jaeger-LeCoultre management and is truly the result of JLC’s collective effort and aspiration. We made a tour of the Manufacture last month to see the work involved in making of this Grande Complication and we spoke to the management, the product department, the prototype department, the Constructeurs etc to learn as much as possible about this new breakthrough.
