The collection opens with the Master Hybris Inventiva Gyrotourbillon À Stratosphère, which improves upon prior Gyrotourbillon models by taking the oscillator through 98% of possible positions. Initial thoughts The impressive movement of the Stratosphere was ostensibly developed to improve accuracy, and on a theoretical basis the multi-axis design should go a long way to eliminate positional errors. Of course, in reality it’s difficult to outperform simplicity. That said, the new cal. 178 is a thoughtfully engineered and impressively constructed mechanical sculpture that does credit to its maker, showcasing JLC’s breadth of capabilities. It’s also quite wearable by the standards of its category. Some past Gyrotourbillon models suffered from excessive size - namely the ungainly Reverso Gyrotourbillon 2. Fortunately, the Stratosphère is comparatively sleek at just 42 mm, though the movement uses every bit of its 16.15 mm thickness.
