Since it was founded in Switzerland in 1833, Jaeger-LeCoultre has relentlessly pursued watchmaking innovation, and its new Master Grande Tradition Gyrotourbillon Westminster Perpétuel model is its most advanced multi-axis tourbillon yet. The redesigned tourbillon is smaller than in previous examples, making it more suitable for everyday wear. The four-phrase Westminster chime – the famous melody of the Big Ben clock – plays at each quarter of the hour, and the perpetual calendar function displays the correct date without the need for manual adjustment between months of different lengths.
