HMX Black

Certified Pre-owned

Story of this machine

HMX holds a very special place among our Horological Machines: it celebrated our 10th anniversary in 2015 (“X” as in the Roman numeral for 10). It was conceived as a thank you to the Friends who had supported us during that first decade; rather than developing an ultra-complicated, ultra-expensive anniversary timepiece – standard practice in the luxury world – we cut margins without sacrificing quality, offering a true Horological Machine at an unprecedented price.

Inspired by sports cars, like the HM5 and HM8, it is built around the same unique combination of mechanical and optical engineering: the automatic movement’s jumping hour and trailing minute discs are reflected vertically thanks to an optical prism in sapphire crystal.

The HMX was presented in 4 limited editions of 20 pieces each in black, red, blue or green; the entire 80 pieces were sold out within two months and we continue to receive requests for this very special anniversary piece.
