388
The Jaeger-LeCoultre Calibre 388 is a hand-wound movement developed and manufactured in-house, based on the patented Duometre concept with two independent gear trains—one dedicated to timekeeping, the other to complications—linked by a single escapement for uncompromised precision. Its most striking feature is the Heliotourbillon: a triple-axis tourbillon composed of 163 components and weighing less than 0.7 grams, rotating in a dynamic motion to enhance chronometric performance and visual spectacle.
