Ariadne Grey chronograph with a frosted grey dial and the moon phase at 6 o’clock

Collection of the Stars - CKAR3344

CVDKAriadne Grey

The CVDK Ariadne Grey combines a full chronograph, calendar indications and a Super-LumiNova moon phase within a compact 40 mm case. This version pairs a frosted grey dial with applied rhodium-plated indexes and circular-brushed counter rings, creating a more restrained and contemporary interpretation of the Ariadne.

A darker expressionof the Ariadne

The Ariadne brings together a wide range of mechanical indications within a balanced 40 mm design. Chronograph counters, calendar functions, a 24-hour indication and moon phase are arranged across the dial while maintaining clarity and structure.

In this grey version, the frosted anthracite surface gives the watch a more understated character. Rhodium-plated indexes and the brushed counter rings provide contrast and precision, while the black ostrich foot leather strap continues the darker tone beyond the case.

Specifications

The Ariadne combines hours and minutes with small seconds, a 24-hour indication and a complete calendar displaying day, date and month. Its chronograph measures elapsed seconds, minutes and hours, while the moon phase at 6 o’clock adds the astronomical indication.

Caseback

The CVDK Ariadne Grey is driven by the automatic CVDK7758. The movement uses 25 jewels and offers a power reserve of up to 48 hours, powering the time, calendar, chronograph and moon phase indications.

Chronograph & Moon Phase

The Ariadne combines a full chronograph with calendar and astronomical indications. Elapsed time is measured through seconds, a 30-minute counter and a 12-hour counter, accompanied by day, date, month and a 24-hour indication.

At 6 o’clock, the moon phase shows the progression of the lunar cycle. When the Moon appears to the left of centre, it is in its first quarter; at the centre, it is full Moon; and to the right, it is in its last quarter. When the Moon disappears, the window reveals a starry sky and indicates new Moon.

The Ariadne after dark

Super-LumiNova gives the Ariadne’s moon phase a different expression in low light. The indication at 6 o’clock remains visible after dark, allowing the position of the Moon within its cycle to be read clearly.

Against the darker grey dial, the luminous effect becomes especially distinct, adding a second visual layer to a watch otherwise defined by its restrained palette and mechanical complexity.

Made in theCVDK atelier

The CVDK atelier produces only a limited number of watches each year, allowing every watch to receive the attention its construction and finishing require. Each watch is assembled by hand, subjected to extensive quality testing and delivered in a dedicated CVDK presentation box with a three-year warranty on the movement and case.
