Master Grande Tradition Gyrotourbillon Westminster Perpétuel

Jaeger-LeCoultre 2019

ref. Q52534E1, Q5253420
Men's

The Hybris Mechanica line represents the pinnacle of watchmaking at Jaeger-LeCoultre, as demonstrated once again by this Master Grande Tradition. Eighteen will be made with a silver grained dial and eighteen with a blue enamel dial. Three of the most emblematic complications in watchmaking are brought together here. They are a bi-axial Gyrotourbillon with a constant-force mechanism, a double guarantee of precision; a minute repeater whose Westminster chime recreates the four-phrase melody played by Big Ben, and a Perpetual Calendar whose date can be adjusted forwards and backwards. This is, beyond any doubt, one of the year's outstanding timepieces.
