The Master Grande Tradition Gyrotourbillon Westminster Perpétuel is the latest generation of multi-axis tourbillon to emerge from Jaeger‑LeCoultre, following the 2004 Master Gyrotourbillon 1, the 2008 Reverso Gyrotourbillon 2, the 2013 Master Grande Tradition Gyrotourbillon 3 Jubilee and the 2016 Reverso Tribute Gyrotourbillon.
Further advancing the art of multi-axis tourbillons, the Master Grande Tradition Gyrotourbillon Westminster Perpétuel features a tourbillon that is significantly smaller than those in the preceding Gyrotourbillon timepieces. As a rule, reducing the size of a mechanism also reduces its error tolerance, which is why successful miniaturisation efforts are so highly valued and complex. In creating a smaller tourbillon, Jaeger‑LeCoultre has created a truly wearable Gyrotourbillon, bringing high complication out of the watch safe and onto the wrist for everyday enjoyment.
The Westminster chime is familiar to everyone as the famous melody of the Big Ben clock at the Palace of Westminster in London. Its four-phrase melody is composed of four notes played in different sequences and different quantities at each quarter of the hour. The Master Grande Tradition Gyrotourbillon Westminster Perpétuel uses four sets of gongs and hammers to create the Westminster chime to indicate the quarters when the minute repeater is activated, incorporating a complex mechanism that places it at the most prestigious tier of chiming watches.
The most beautiful chime can be marred by interruptions and gaps of silence between the strikes. In order to create a chime of unmatched euphony, the Master Grande Tradition Gyrotourbillon Westminster Perpétuel has a silence-reduction function built into its chiming mechanism.
This ensures that even when the full set of Westminster quarters is not struck, there is no time delay corresponding to the missing quarters before the minutes are struck. In every instance of the chime when the Master Grande Tradition Gyrotourbillon Westminster Perpétuel is activated, the hour strikes, quarter strikes and minute strikes are seamlessly joined.
The Master Grande Tradition Gyrotourbillon Westminster Perpétuel is the result of 186 years of fine watchmaking expertise and a spirit of innovation that continues to this day. Reflecting the blend of patrimony and modernity is the design of the watch, which emphasises the round profile of the Master Grande Tradition case.
A retractable minute repeater pusher, first seen in the Master Ultra Thin Minute Repeater Flying Tourbillon, preserves the smooth lines of the case. Hand guillochage, fine hammering (martelage) and grand feuenamel are part of the canon of fine watchmaking finish and have been practiced at Jaeger‑LeCoultre throughout its history — most outstandingly in the dazzling Hybris Artistica collection.
In the Master Grande Tradition Gyrotourbillon Westminster Perpétuel, however, these finishes are expressed in a subtle and contemporary way, culminating in the openworked dial — produced either in a striking deep-blue grand feu enamel or in a more classic silver-grained version — showcasing the mesmerising multi-axis tourbillon.
These age-old techniques are skilfully practised by master artisans from the in-house Metiers Rares atelier of Jaeger‑LeCoultre, where haut-de-gamme traditional finish is also applied to the movement by hand.
