CVDKHypernova Guilloché Black

The CVDK Hypernova Guilloché Black combines a full chronograph with calendar functions, a day/night indication and a Super-LumiNova moon phase. Its black guilloché dial gives the watch a more graphic and nocturnal character, while luminous accents maintain clarity after dark within the 44 mm stainless steel case.

A darker expressionof the Hypernova

The Hypernova brings together a remarkably broad set of indications within a dial that remains balanced and legible. On this black version, the guilloché pattern creates a subtle play of light across the surface, while the lighter indexes and luminous elements stand out more sharply.

This darker execution also changes the character of the astronomical display. The moon phase at 6 o’clock and the luminous hour markers become especially pronounced in low light, giving the watch a distinctly different presence between day and night.

Chronograph & Moon Phase

The Hypernova combines several practical indications with a distinctly astronomical display. The chronograph measures elapsed time through a central seconds hand, a 30-minute counter and a 12-hour counter, while the dial also integrates day, date, month and day/night information.

At 6 o’clock, the Super-LumiNova moon phase shows the progress of the lunar cycle. When the Moon appears to the left of centre, it is in its first quarter; in the centre, it is full Moon; and to the right, it is in its last quarter. When the Moon is not visible, the display has reached new Moon.

The Hypernova after dark

The luminous elements of the Hypernova give the watch a second identity once the light fades. Selected hour markers, the hands and the moon phase remain visible, preserving legibility and reinforcing the astronomical atmosphere of the display.

On the black guilloché dial, this effect becomes even more pronounced. The contrast between the dark surface and the glowing indications gives the moon phase and time display a clear, almost floating appearance at night.
