SISTEM BLUE (SUTS401) is the colour of cosmic nights, a message from the hot blue stars of the Pleiades to our beautiful blue planet. Clustered around the centre of the deep black dial are 6 red points indicating 6 of the movement's 19 rubies, glowing red signals from the movement within. Narrow white lines connect a scattering of star-white dots, tracing a path for us to follow, a map to guide our cosmic journey. Twelve white dots mark the hours on the black bezel set within a luminous, translucent blue case. And on the reverse we discover an amazing sight—a deep blue and black star-burst, a radiant pattern expanding from the central screw to the oscillating weight, the motor of the extraordinary mechanical movement that is SISTEM51.
