Product Details

The ExoTourbillon Chronographe is the first timepiece in the Montblanc Collection Villeret 1858 to unite a tourbillon and a chronograph function. It is the world’s first tourbillon to have a balance, being larger than the cage, that oscillates outside of the cage on a higher plane – thus giving rise to the name ExoTourbillon. An innovation so unique a patent has been applied for.
