The Moon, fully luminescent (BGW9), is built on a realistic representation of the star. A femto laser, precise to the micron and at a frequency of 10⁻¹⁵ seconds, is used to dig and burn the material at different intensities. Each crater is revealed and turns brown, with a relief perceptible to the naked eye.

This innovative printing method is a first in the watchmaking sector. It was developed in collaboration with the miniaturization workshop AJS Production , which was awarded at the EPHJ trade fair in 2016 in Geneva.
