horlogical machine n°2



Horological Machine N°2 is a holistically conceived and engineered three-dimensional timekeeping machine. HM2 features the first world's mechanical movement offering: Instantaneous Jumping Hour, Concentric Retrograde Minutes, Retrograde Date, Bi-Hemisphere Moon-Phase and Automatic Winding.

Horological Machine N°2 is an incredible sophisticated micro-mechanical work of art with over 450 components making up the case and movement; however its complexity has been carefully engineered for functional simplicity.

The dynamic tension between apparently incongruous elements in Horological Machine N°2, such as that between cutting-edge technology and sculptural art, matte finish and mirror polish, high-tech alloys and precious metals, and between traditional watchmaking and 21st century micro-engineering, endows this impeccably finished machine with vibrant vitality.

Horological Machine N°2 takes one last bow on center stage with two final limited editions of 18 pieces each, both featuring sapphire cases: HM2-Black SV and HM2-Red SV close the HM2 collection, thus ensuring its exclusivity.

set the date

The sliding crown guard has 3 positions:

1. “In” position = Normal position when wearing the watch and winding crown.

2. Intermediate position = Slide the crown guard to the first notch and turn the crown to the correct date. Slide the crown guard back against the case when finished.

set the time

“Out” position = Fully slide the crown guard out and turn the crown to the correct time. The minutes can be adjusted both clockwise and anticlockwise. Slide the crown guard back against the case when finished.

Your watch is equipped with an automatic movement. If it has stopped, check that the slide is fully in (position 1) and wind the crown a few turns.


To adjust the moon phase, gently position the supplied tool in the corrector hole, which is located on the left-hand side of the case. To avoid damaging the moon phase gear train, do not adjust the moon phase between 9 pm and 2 am.
