Jaeger-Lecoultre Master Grande Tradition Grande Complication White Gold.
Unveiled in 2010, the Master Grande Tradition was not far from perfection, with a very nice dial, its tourbillon which turns all around the dial, and its improved minute repeater with the Trebuchet hammers borrowed to the Duometre à Grande Sonnerie, introduced in the catalog one year before.
We had to wait five years to see this watch enjoying a new Master Grande Tradition case, much more elegant, but curiously, in rose gold, only.
I took some pictures of the rose gold and white gold versions, to prepare a review I will soon post.
But in the meantime, enjoy this picture!
