Detailed features & specifications
The meticulous finissage of the 684 components of the calibre L133.1 – one of them is the entire chain – reflects the manufactory’s quest for perfection.
In particular, the traditional black polish of the tourbillon bridge integrated in the dial illustrates this ambition: here, the time-consuming technique has been applied to curved surfaces for the first time. It requires not only extreme dexterity but also involves several hours of manual work.
This model was introduced in 2017. The dial is crafted from solid silver. The hands are made of rhodiumed gold, blued steel and gold-plated steel.
