The watch features a free-sprung balance, a balance wheel design that offers increased shock resistance. Unlike other balance wheel systems that rely on additional regulating mechanisms, the free-sprung balance allows for more resilient and accurate timekeeping. This design ensures that the watch maintains its exceptional precision, even when subjected to sudden impacts or movements.


Versatile and Resilient Full Ceramic Design

With its full ceramic construction, this watch combines versatility and resilience. The lightweight ceramic material ensures comfort on the wrist, while the scratch-resistant properties of the ceramic case and bezel guarantee long-lasting durability.
