About Lausanne Tourbillon
The Lausanne is further enhanced with a sun-moon phase and a sapphire crystal, all encased in a 5 ATM water-resistant design. Its pumpkin-shaped crown allows for smooth, responsive winding, adding to the pleasure of operating such a sophisticated mechanism. The visible tourbillon cage exhibits a rhythmic rotation, allowing the wearer to experience the micro-mechanical dance of the escapement as it rotates within the cage.| Reference | GM-905-5 |
