Jaeger-LeCoultre has shared the 2015 version of their Master Grande Tradition Grande Complication – now in pink gold and sporting a fresh dial design. This very busy and complex watch has an orbital flying tourbillon that doesn’t actually tell the same time as the hands. But spit its complexity, let’s start the analysis…
It is a 45 x 15.8 mm rose gold haute-horology piece from one of the most respected brands in the business. Standard hour and minutes are shown on the large and legible pink gold dauphine hands so, regardless of the myriad of other features, the Jaeger-LeCoultre Master Grande Tradition Grande Complication is first and foremost, a watch.
Next up is the orbital flying tourbillon which makes one revolution of the dial every sidereal day (23 hours, 56 minutes, 4 seconds). Given that sidereal time is not especially useful and that tourbillons are just for ornamentation, this artistic and entertaining application exists for added drama and complexity, which it succeeds in providing.
Beneath the tourbillon we find a brilliant blue sky chart dial of the northern hemisphere and many of its constellations, including the 12 of the zodiac. Surrounding the dial is a 24 hour scale that combines with the position of the dial and a small sun indicator to offer standard 24 hour time (and am/pm) as well as month and zodiac indication.
So while the sky chart may add (considerably) to the visual complexity of the dial, it’s a passive element, with the remaining displays kept on the outer edge of the dial, safely out of the tourbillon’s pat.
All of these features are supported by Jaeger’s calibre 945, a 527-part behemoth of a movement that is actually thicker than my Seamaster (12.62 mm thick, movement alone). With a running rate of 4Hz and a power reserve of 40 hours, the 945 has a silicon escapement and uses 29 jewels. Assembled by hand and rendered in german silver, the 945 is then treated to some of the finest finishing in the business.
