The fully skeletonised HMC 811 is an automatic, three-dimensional calibre housing H. Moser & Cie.’s in-house cylindrical hairspring and the one-minute flying tourbillon for impeccable precision.


The cylindrical hairspring offers superior, thanks to a period of oscillation that is constant – regardless of amplitude. Combined with a tourbillon, it is at once a feat in precision and a kinetic sculpture to admire.


Lending a new dynamic to the traditional art form of enamelling with the use of a pattern engrained, as if hammered, onto a gold base and three different colour pigments that are melded together. The result is a textured and immaculate fumé aesthetic for a captivatingly contemporary finish.
