CVDKAriadne Sapphire Smoked Blue

The CVDK Ariadne Sapphire Smoked Blue gives the familiar Ariadne a more refined, technical character through its transparent smoked blue sapphire dial. Dark blue calendar and moon phase discs create depth beneath the dial, while SuperLumiNova details add a distinct luminous presence. Paired with a navy-blue FKM strap, this version combines the full Ariadne complication with a contemporary celestial appearance.

Ariadne intransparent blue

The Ariadne Sapphire Smoked Blue introduces a different visual language within the Ariadne family. Its smoked blue sapphire dial reveals the layered construction beneath, allowing the mechanical depth of the watch to become part of the design itself.

Dark blue day, month and moon phase discs keep the composition tone-on-tone, while the transparent sapphire surface changes character depending on the surrounding light. Combined with matching blue details and a navy-blue FKM strap, this version brings a distinctly modern expression to the Ariadne complication.

Chronograph & Moon Phase

The Ariadne brings together a full chronograph, complete calendar and moon phase in one integrated composition. Elapsed time is measured through central chronograph seconds, a 30-minute counter and a 12-hour counter, while day, date, month and 24-hour indication complete the display.

At 6 o’clock, the moon phase adds the astronomical element. When the Moon is positioned to the left, it is in its first quarter. When centred, it is full Moon. When it moves to the right, it is in its last quarter. If the Moon is no longer visible, the display indicates new Moon.

Extended SuperLumiNova details

The Ariadne Sapphire Smoked Blue features more than the familiar luminous moon phase. The day and month indications also use SuperLumiNova text, allowing these calendar displays to remain clearly legible in low light.

SuperLumiNova is furthermore applied to the chronograph seconds hand and the tip of the date hand, extending the luminous accents across the dial. Together, these elements give the smoked sapphire construction a striking appearance after dark while preserving the refined tone-on-tone character of the watch.
